Localization

US localization

The "LITHOSTAR Multiline system" is a multifunction workstation for diagnosis and therapy involvin g extrac orporeal shock wave lithotr ips y w it h radiographic and optional ultrasound imaging. The system is excellent for the treatment of stones throughout the entire urinary tract as well as for all suitable auxiliary treat m ents required.

Laser light loc alizer for preposi tio ning the patient

The system includes an undertable X-ray unit permanently mounted on a Carm. In addition to conventional use of the system for diagnostic purposes

(0°), the C-arm can be moved orbitally for the purpose of stone localization (-10°/30°).

The focal point of the shock wave head (maximum shock) is located in the center of both localiz at ion ranges (isocenter). In line technology enables observation of ston e f ragmentati on t hrough the sh ock wave source.

Additional stone localization is made possible via the ultrasound monitor by inserting an ultrasound probe in the shock wave head (Inline Position).

Oper ating modes

The system is controlled at a control console via a PC with keyboard and mouse as well as a tableside control. A tableside control is also available on the patient table. The table can be lowered to 720 mm to provide comfortable access for the p at ient.

A tableside control is loc at ed on the Ultra so und unit for important fu nc t ions such as: probe movement, shock wave release, shock wave counter, probe angle display.

Hardcopy doc um entation is als o possible us ing film (cassette size 35 x 43 cm) via an insertable cassette holder.

To guarantee system functions, only service engineers with work authorizations for the LITHOSTAR Multiline may service this system.

Two operating modes are possible: Diagnostic mode (table insert locked in)

Therapy mode* (table insert removed) *with X-ray or ultrasound localizat ion

DUEP Interface 2

DUEP

Function

Serial dat a t rans m ission bet we en the master (Com con t roller D6) and th e slaves (e.g. operatin g panels or image memory, etc.) occurs via a Siem ensstandarized data transmission protocol (DUEP).

The DUEP inter face is a 20mA current lo op. Each curr ent loop has an LED as indicator on bo ard D6. If the LED is "ON", it means: the loop is connected and 20 mA are present.

DUEP 1: Current loop 1 Tableside controls (system, US unit, NBFFT) DUEP 2: Current loop 2 Operating PC DUEP 3: Current loop 3 Shock wave system DUEP 4: Current loop 4 Tableside control at the PC DUEP 5: Current loop 5 Image memory

Telegra m s co nt aining comm ands to be performed are sent via the s e c urrent loops (e.g. selecting functions or increasing values etc.). Even if no commands are p r ese nt , th e COM c ont ro l ler (D6 ) co nt i nuo usl y ch ec ks t he f unc ti on of the interface. If n o s igns of life are present, the COM c ontroller trans it ions to a security level and sends a failure message to the Host (D1). An error message is displayed.

Possible causes of error

Connection to the slave has been interrupted (e.g. damaged cable). The LED goes out. Connection to the slave has shorted out. Assembly for resp ec t ive DU EP is defective.

The se r vi ce engineer (FSE) can d eactivate slaves via the service program. This can be useful during error localization. This method should, however, only be initiated by experienced service engineers. For example,

it is typical to see the LED’s flash sequentially in the operati n g keys if initial co n tact from the op er ating panel (D41) to the master (D6) does not occur.

NOTICE

Step 1:

Switching the system off from the generator provides additiona l sa fety for the servi ce engineer becau se the system cannot be switched back on from the control console.

• Starts bo ot soft ware

• Initialize operatin g system

• Processor system self-test

Simply stated, this first step initializes and tests the HOST board D1. All subsystems are initialized in parallel.

The PC can be connected following completion of the first step. Step 2:

• Starts initialization tasks

The version number of the HOST software is compared with the version number in the EEPROM.

Establishing contact with the subsystems

Siemens AG Register 7 RXL2-120.041.01 Page 3 of 6 LITHOSTAR Multiline Medical Engineering Rev. 03 09.97 TD SD 34

If there is a discrepancy, the HOST will send an error message and will transition to a wait lo op. Onl y by dow nloading th e operating sof t war e in t he EEPROM is it pos s ible t o c ontinue the initializatio n.

Step 3:

• Initialization routi nes of the subsystems

Contact with the subsystems is established in this part of the initialization. In principle, the subsystem must contact the HOST after initial contact is established and vi c e versa. As a rule, three attempts will be made to establish contact to the other if errors occur during this data exch ange . If these atte mpts fail, the systems will transition t o a s ec urity level and an error messag e w ill be displayed.

General

Movement command

Relative current position

Absolute current position

Travel range

By activati n g a key o n th e control pan el (ta bles ide or operati ng PC ) a command is activated (FB) and the following oc c urs:

➪ Via the DUEP interface and the Com Controller D6, the movement

command goes to the HOST D1.

➪ The Host forwards the command, speed to the responsible motor con-

troller (D 4A, D4B).

➪ The motor controller activates the motor via the end stage D7x and

the movement begins.

➪ An incremental transmitter (Bx) connected to the motor axle reports

the curr ent position (M C value ). T he m otor contr oller transmits t his actual value to the HOST for further evaluation.

➪ At the same time, the potentiometer that acquires the system position

is also turning. Th e analog value p roduces the abs olute actu al val ue of the po te nt iometer after conversion in the A/D conver te r (D 5). This ADC value is read out by the Hos t at regular intervals.

The travel range is limited by means of software limit switches (SE) and safety limit switches (refer to the safety circuit).

Reference switches

possible err ors

This value is de te rmine d in t he testing field and can not be change d by the serv ic e engineer.

The reference switches (S1-S9) are necessary only to monitor the potentiometers. They are loc ated at certain points within the travel range ( e.g. sy stem long itudinal travel zero position, etc .) and are activated by a switch ca m , e .g. each time t he drive pass es th e switch cam. When the HOST receives the message via the I/O port (D5) ” Ref.switch on”, it checks the current actual

value of the potentiometer where the value is stored for this reference switch.

THIS IS OF GREATEST IMPORTANCE IN THE THERAPY POSITION. In the therapy position , th e sh o ck wave focus must c o incide with th e

cross hairs target.

The H OST basically rec ognizes hardware errors or communi c at ion errors between the processor systems.

If a motor, an actual valu e potentiom et er or an encoder is defective, the HOST imm ediately is s ues an error message. For example:

➪ The difference between the ADC value and the MC value is too large

(two-channel acq uis it ion).

possible err ors

Notice

➪ or the potentiometer value deviates from the reference switch nominal

posit ion

➪ or the Rx potentiometer has a broken wiper, etc. The error m es s age is read out at the HOST (D1 ). There are c erta in im port ant items th at th e s ervice engineer mu st kn o w:

1) After executing a switch-on or Reset, the values ADC position = MC position must be identical in the service program: DIAGNOSTIC / MONITORING. The operating software sets the first position value (starting value) for the motor controller (MC position) based on the a ctual value of the p ot entiometer su pplied by the A/D c onverter (AD C position). Thereafter, the encoder s upplies the difference betw een the actu al position and the current posi ti on. T he encode r c an m easure on ly relative values.

2) In the service program menu ”ADJUSTMENT/CALIBRATION”, there is an ”UNREGULATED MODE” selection that allows th e motor to be moved without feedback signals from the potentiometer or the encoder. The sele c te d m ot or will move at reduc ed speed in th is operating mod e (can be adjusted via th e s ervice PC). This ope rat ing mode is us ed for calibration an d for er ror removal (e.g. drives in the safety circuit).

Safety informat ion

Use CAUTION when operating the system in ”UNREGULATED MODE”. A collision can easily occur since the monitoring functions are disabled. Watch all moving parts of the system.

NOTICE

The reference switches are not monitored in urology mode (table insert). In case of an error, e.g. reference switches not ok in therapy position, you can switch over to urology mode and move out of this position after performing a syst em reset.

FUNCTION

Large dr ive s

All drives have been provided wit h limit switches at the end of their respective travel ranges. If the drive exceeds the end position established by the software (system malfunction), the limit switch closes and interrupts the safety circuit (SK). Result: th e operating voltag es for the m otor end stages (D7A...D7F) are switched off immediately and the HOST tra nsitions to safety mode. An error message is transmitted. T he drive cannot be moved from this position (m ov ed in the opposi t e direction ) unless s erv ice sw itches S58, S59 are activate d.

As a rule, da nger of patient injur y c an be minimize d by maintainin g t he required sa fety di s ta nc es . A t lo c at ions where t his is not possible (at t he I . I., shock wave head, X-ray tube and cassette holder), additional collision protection switches have been prov ided. The safety circuit is interrupted when a collision protection switch is activated. Howe ver, by activating a sa fety switch (at the patient table) the system can be moved out of this position in the opposite direction. While the system moves in the opposite direction, an audible signal sounds. If the system travels further into the direction of a collision , th e s ignal chang es t o a higher freq uency.

One emergency stop button is located on the patient table and a second is on the PC cont rol desk. When the em ergency s to p but to n is pressed, the voltage supp lied to the drives is inte rrupted . A ll m ot orized movement s, radiation an d s hock wave release are immediately stopped.

Function

Feedback signals COM Controller A/D Converter

Switch-on phase

Contacts K1, K2 V14, V10

The HOST controls and monitors the safety ci rcui t (SK) for the large drives with the assistance of the COM-Controller. If the safety circuit is open, i.e. a safety switch is activated, the Host transmits an error message that refers to the type of interruption e.g. Emergency Stop acti vated or safety switch responded (refer to the er ror list).

The HOST receives information on the status of the safety circuit from the COM cont roller via the input ports (e.g. P3 2 I N 0). The HOST can verify whether the voltage values are correct via the A/D converter.

1) K10/24V switch on. Provided that all s afety s w itches are in the normal posi t ion, relays K1 an d K2 switch on. The relay cont ac t s of K1, K2 transmi t the operating voltages to the mot or

end stages D7A, etc.... and V14 and V10 light up. The HOST receives the

feedback signa l v ia c hannel 7 of the A/D converter and P3 3I N 0. Relay contac ts switched on .

2) K10/24V switch off The HOS T switches off the operating voltag es to th e m otor end sta ges. Via the feedb ack c hannels (re fer to the above) , the HOST ver ifi es whethe r t he R elay contac ts ar e frozen.

3) K10/24V switch on This is the las t st ep in the switch-on ph as e. Af te r switching on the operat ing voltage for the motor end stages and running the subsequent test, the system transitions to Standby mode once initialization is complete.

NOTICE

Siemens AG Register 7 RXL2-120.041.01 Page 5 of 9 LITHOSTAR Multiline Medical Engineering Rev. 03 09.97 TD SD 34

If the contacts freeze or do not switch off, the Host will recognize this error and will transmit an error message.

The processor on board W16 counts the shock waves released and transmits the counter status to the HOST.

When a new p at ient is entere d, th e c ounter is res et to zer o v ia a c ommand from the Host.

The energy level default on the operating monitor is fed back to the HOST for safety reasons and is also displayed on the monitor screen.

Shock wave release

Shock wave release or service

Only when all the conditions for shock wave release have been satisfied can shock waves actually be released. This means:

• There cannot be any overtemperature condition, flow interruption or water

pressure abnormality present in the cooling circuit. The shock wave head must be located in the therapy position and the coupling pressure must be correct.

• No errors can be present in either the shock wave generator or the charging

unit.

• The cone l ongitu dinal dr ive must be posit ioned c orrect ly.

If switch S3 /W 12 is s et in position 2, sh ock wave releas e is possible in th e therapy position without coupling pressure.

Tasks of the Coupling control

Shock wave head

The cooling system is part of the shock w av e system and is l ocated in cabinet A13. It consists of:

➪ Coupling control (W12) ➪ Water cooler (W11)

The coupling control (W12) regulates the amount of water and the water pressure in the sh ock wave head in the gel or therapy positions.

This result s in optimal co upling of the s hock wave head and initia ti on of the

shock waves in the patient’s body. The control electronics is locat ed in N12 on bo ard W12. Pneumatic control elements are located directly on the water reservoir (valves, air pumps, etc.). Board W1 (sensor module) is located on the shock wave head.

The shock wave head consists of tw o s eparate cham bers filled w it h wa te r. The upper chamber of the s ho c k w a v e head i s us ed fo r cou pli n g to th e pa ti en t (via a flexible coupling bellows). The lower chamber of th e s hock wave head is used for cooli ng t he shock wave source. The static and dyn amic pressure in the cool ing circuit pre s s es th e m embrane on t o t he c oil of the sho ck wave sourc e (imp ort ant for the def lection of the membra ne). T h e s ensor module is attached t o t he shock wave head.

Coupling pr ocess

Water is pumped into the shock wave head with using air pressure (pump M1) until the correct coup ling pressure is reached . A t the same time, th e wa te r reservoir is monitored (fill level). If the coupling pressure becomes t oo high, water flows back into the water reservoir via gravity feed after a va lve is opened.

The coupling pressure

➪ is monitored at the s hock wave head by means of a pressure s ens or. ➪ is selectable in three levels (at the operating PC).

Water pressur e

Pumps water through the cooling circuit and should be set to approximately 25l/h with R 5. T his flow rate produces the measured co oling effect for the shock wave source. The shutoff rate is 20l/h.

The temperature sensor monitors the water temperature directly at the shock wave head The v oltag e at me asurement point X2.2 changes by approx. 200mV/ °C.

If the temperature ri se s above 3 8°C (7.6V at X2. 2), shock wave release is blocked.

When the sh ock wave head reaches t he park po si tion after co m pletion of patient treatment, c ooling continues for approximat ely 5 m ore minutes. Af t erward (shock wave head in th e park posit ion for at least 5 minu te s and water temperature at e25° C), it is switched over to partial flow (approx. 10l/h) and pressure regulation is blocked.

The w ater pressure in th e c ooling circuit is also a c quir ed directly at the s hock wave head. The acc eptable press ure range is be tween 265 mb ar and 395 mbar. This means that a voltage of between 4.6V to 5.4V should be present at measurement point X2.3 (approx. 6 mV/mbar). If the voltage value is above or below the se lim it s th e following occurs:

Wat er press ure sw itch 800 mbar

Voltage > 5.4 V (335 - 465 m bar): Water is forced into the reser ve tank t o decrease t he pressure. M15 is switched off and Y1 is turned on. Voltage < 4.6V (225 - 310 m bar): Water is forced out of the reserve tank to increase the pressure.

M15 is switched on and Y1 is turned on. Pressure switch S4 is located in the control cabinet on the pressure side of

NOTICE

Regulat ion process

As already described, the water pressure in the cooling circ uit is acquir ed by the pressure sensor at the shock wave head and is relevant to the application of a regulat ion process.

Depending on the wat er pressure, two proc esses can occur:

• Water is forced back into the reserve tank if

p > pnom / Dra in proce ss.

• Water is f orced by the pump i nto the co oling c ircuit if

p < pnom / Fill process.

Since the system is inclined to oscillate easily, a t im e m ask is superimposed on the regulation pro c es s.

One regu lat ion period equals 3 2 units (appox. 5 se c onds). Of th is, 4 c an be used for the fill process (p < pnom) and16 for the drain process (p > pnom). A pause follows until the 32 units have expired.

Relea se s w it ch es (D28/ S1, US- NB F/S1 , S5 5) on th e co nt rol pan el 24 V ➝ D6 of the Com-Controller. Data exchange takes place with the HOST D1 in the Com-Controller. If all systems are working without errors, the release command can be forwa rde d to the shock wave system via D6. The type of triggering depen ds on the opera tin g m ode select ed.

Release si gnals for Respirato ry / ECG Trigger ing are transm itted from D 25. From D6 Com-Contr. ➝ via t he DUEP inte rface ➝ to the system controller. At the sam e t im e, the release request goes to W 16; this means: ”software

and hard war e requireme nt s for the release of a s hock wave must bot h be present (dual protect ion). Relays K2/W16, K1/D 91, KR1/2 D19 and K1 W 15 are switched o n or are correct ly s et .

The system control ler W16 v erifie s the rel ease request and ini tiates the sho ck wave release request. If the energy level is accep t able and the cooling and coupling circuit s answer "ok", the signal to start charging can be released via relay contact K1 to M18. (D91 and D 19 must not indicate errors). Charging unit M18 ch arges the ca pacitor in the s hock wave generator to the default KVno m inal value. The charging proc es s is m onitored by D91 and D19.

Controller W16 gives the "shock wave release" signal after the end charge signal and generates a trigger signal via W15 to D12. D12 converts this 5V trigger s ignal to a signal of approx. 30 0V.

This value is converted again by a factor of 100 in th e s hock wave generator N70 so that the spark gap can be ignited with this signal.

Preliminary remarks

Film acquisition

Fluoroscopy preparation

The Lithostar Multiline offers the following operating modes for generating images:

• 43cm x 35cm film acquisition with cassette holder

• Fluoroscopy

• Snap shot (for MULTILINE with POLYDOROS SX and 33 cm I.I. only)

(DR Digital Radiography)

At the operating PC, the acquisition kV and mAs values are entered using the exposure tables (2-point technique). Radiatio n is th en release d at th e operating console using the han d release switch or the footswitch. Th e footswitch at the table pr ovid es a t hird release option. Exposure time depends upon the output level selected (100% or 80%) as well as the data entered.

On the operating PC, selec t from: Fluoroscopy curve (Antiisowatt or 63KV; 1or 2)

Fluoroscopy can be released using the handswitch or the footswitch. The FL request is transmitted directly to the D6 Com controller. (Port P30 IN0-IN4).

The D6 Com controller forwards the FL request to the HOST D1. The HOST transmits a FL request via the XCS-Contr. D2 and the XCS net-

work to the system controller XCU D200 (D320 for PSX). The request is sub- sequent ly forwarded to the generator controller D100.

Regulat ion is control led via the fluo ro c urve selec t ed and the br ightness actual value (dose rate control) of the TV central (Videomed DIM).

The iris diaphragm op ening depends on the s y stem config urat ion. On the Polydoros LX, it com prises only one ap ertur e w hereas on Polydoros SX, (snap shot, 33cm I.I.) it comprises several.

The radiat ion feedback signal is tra ns m it t ed via the XCS network to t he HOST.

The goal is to store the image content (B) of the BAS signal and following conversion in the Memoskop 100, to display it on the two 100 Hz monitors.

On the Memoskop 100, select Fluoroscopy mode and "Last Image Hold." The Memoskop is switched by the Host to Fluoroscopy mode when the radiation

When the radiation hand switch (or footswitch) is released, (no longer activated), the HOST receives the message "Fluoroscopy off." The HOS T ca nc els the START signal to the M emoskop10 0, wa it s for the acquisition signal to be withdrawn an d t hen forwards the ”F luoroscopy off” message via the XCS network to t he Polydo ros generator.

A DR requ es t is iss ued by the operat ing system . The gray filter is moved in w ith precontac t a nd t he TV iris is clo s ed to the DR

format to filter light coming from the I.I. output window. (VK / HK, refe r to the left side)

The following actions occur between steps 5 and 6: When radiat ion is switched o n, a bright image is produ c ed on the output screen of the image intensifier. In proportion to the brightness of the output screen, th e PDA sensor (pho to diode array) gene rat es a s ignal that is forwarded to the Iontoma t u nit of th e generator a nd w hich shuts of f radiation once the n om inal dose a m ount has been reache d.

While radiation is on, read-out of the CCD chip is blocked and information is loaded onto the CCD chip in the TV camera.

When radiation is shut off, the image on the CCD chip is read out and filed in the image memory.

Interface

Kidney stone localization is performed with the LITHOSTAR Multiline (V ersion

4) using X-rays and ultrasound imaging . Ul tra so und localization is known as the "Inline " process an d X-ray localization as the "Outline" proce ss. Inline means: th e I nline LITHO ult ras ound probe is mount ed in the cone of th e shock wave head, therefore in the sym m et ry axis. For localization and positioning of a kidney stone, the cone (ultrasound probe) can be rotated and moved in the longitudinal direction. This is controlled from the Ultraso und tableside c ontrol pane l.
