INTRODUCTION AND TECHNICAL DATA

1. Product information

The Optimus family of generators for radiography is based on computer-controlled converter technology. The converter operates in the non-audible frequency range.

Applicable options are essentially achieved by releasing software modules using customized PAL ICs. Control between the internal Function Units (FUs) and the external online equipment takes place by a CAN bus.

Safety-relevant signals are transferred directly on the so-called “Signal bus”. Units without any CAN interface are operated by the ”Adapter for 4 auxiliary units WA” option.

1.1. Applications

-- Radiography

-- Tomography

-- Fluoroscopy

1.2. Options

Component overview according to the commercial catalogue.

Only the versions in the current commercial catalogue can be ordered.

If an existing generator is to be upgraded the commercial department must order:

There are no assignement restrictions because the measuring chambers are allocated to the auxiliaries in SW programming.

S Withdraw pins 101--102--103 or A--D--H for measuring field selection at the junior / extremity measuring chamber.

These measuring chambers have only one measuring field. The terminal for the left-hand field is used in other configurations for switching over intensification and must not be connected here.

S Connect the photosensor dose output of DSI from Central Part E (BHX 12) to EZX41.

Only EZX41 sends the necessary signal REL (or REL_CH = RELease CHamber) for automatic and non-automatic techniques.

Note

AMPLIMAT cables 9803 507 0xx02 (for hybrid measuring chambers 9803 509 xxxxx) with 3--Plus plugs at both ends must be connected in the generator by the following adapter for each cable:

Adapter for AMPLIMAT cable: 4512 108 09042. The generator includes 1 adapter.

The hybrid measuring chambers 9803 509 xxxxx require connection (chassis) between contacts

D--Sub end GND (13) <---- --> RF 0V (8) (generator input)

3--Plus end GND (N) <------> RF 0V (J) (generator input)

This connection is established by the adapter for the AMPLIMAT cable. See Z1--6 ”Basic interface” in section “Schematic drawings” of the generator manual.

In case of a hybrid measuring chamber 9803 509 xxxxx is not operated with the required

AMPLIMAT cables 3--Plus / 3--Plus 9803 507 0xx02..... .....

but with

AMPLIMAT cables D--Sub / 3--Plus 9890 000 017xx..... .....

make sure to establish this connection (13 <-- -- --> 8) in the D--Sub connector!

For ALC measuring chambers 9890 000 016xx connection GND <------> RF 0V is not permitted. Therefore, ALC measuring chambers AMPLIMAT cables 9890 000 017xx should always be used.

See ”Connection diagram” in section 1.

S Mark the H.V. cables at the generator and the tube end with the correct polarity.

S Fix the H.V. cables on the left-hand side of the wall junction box on the middle rail to provide drag relief for the

cables. The short ends of the H.V . cables which are going to the H.V. generator must be routed in downward direction in this area. The free cable lengths including plugs should be about 1.5m.

S Twist the H.V. cables counter-clockwise by one turn and connect them to the H.V . generator.

The twisting of the cables allows that the H.V . cables can be put into a loop when the cabinet is placed against the wall.

The H.V. sockets should always be filled with some oil. At least the lower half of the plugs must be wet with oil.

Caution!

Do not use a silicone washer.

Do not grease the plugs with silicone.

The union nuts of the high-voltageconnectors must be tightened up to ensure good electrical contact for screening.

Only high-voltage connectors which have threaded flange halves may be used. Older high-voltage cables still have connectors where the flange halves are kept together with a spring washer. In such cases the modification kit 4512 103 8085x is required.

8.3.2. Tube adaptation

Warning! Radiation is released during the adaptation procedure!

8.3.2.1. General information

Tube adaptation is an automatic process which includes:

1. The measurement of the mA offset value that is caused by:

-- the kV measuring circuit

-- the emission current feedback circuit (VCO)

2. The measurement of the individual standby filament current (based on 100µA).

3. The emission current characteristic as f (kV, filament current).

INSTALLATION

4. The dynamic behavior (positive and negative boost adaptation) where the inertia of the filament with respect to heating up and cooling down is registered. For more information refer to section 3: FAULT FINDING.

Note

In case of problems check the symptom / solution list at the end of this adjustment chapter. Repeat the adaptation for this particular focus.

S It is recommended that the high tension be monitored during adaptation.

Connect the scope: Channel1: kV AV HT at EZ130 X3 (1V/div), scale: 20kV/V Trigger external: CTRL_X_C/ at backpanel EZ X74, negative slope Time base: 2ms/div

S Select the RGDV = Free cassette for the tube to be adapted.

S Select menu XRGSCOPE:

OPTIMUS XRG/ ADJUST/ TUBE ADAPTATION

S Select the tube and focus to be adapted, start with small focus!

Note

To avoid any malfunction make sure that READY is displayed on the desk before transmitting data by pushing <F2>: READY state disappears, ADAP is displayed on the desk, WAITING is displayed on the PC screen. Wait until the generator turns back to READY state.

S Start the adaptation process by pushing the handswitch in PREP and EXP position continuously.

The generator switches about 125 exposures for each focus. The radiation sign at the desk indicates exposures but there is no beep at the end of each exposure. The actual kV parameters are displayed during adaptation.

The generator carries out the adaptation automatically. The procedure for one focus is completed when the desk indication changes from ADAP to TEST. The WAITING message disappears from the PC screen together with a PC beep, followed by the screen: BEFORE CONTINUING THE GENERATOR MUST BE RESET.

S RESET the generator.

S Run the adaptation for each focus (small and large) and tube.

Note

As there is no tube type with a physical third (middle) focus yet, the third focus can not be adapted. VARIOFOCUS values are calculated by adapted small and large focus. APR programs using VARIOFOCUS can only be selected until small and large focus are both adapted.

S Set RGDV(s) programming to original status according to table “RGDV programming” 2Z--2.x in the end of this

chapter.

8.3.4. Problems during adaptation -- Symptoms and solutions

1. A warning cannot be displayed on the control desk, the W AITING screen on the PC is flickering instead during this event and logged in the error log index.

2. If the tube has already been at a high temperature level (but the tube load indication still indicates green or green--yellow for 100% power) it might happen that the load indication changes straight to red and the adaptation is on hold. WAITING is flickering on the PC. Solution: Keep the handswitch pushed, once the temperature is down adaptation continues automatically.

Note

An increment of one of the temperature levels inhibits the 100% power condition. This event is always logged as warning 00BV in the error log index.

3. An error message just flashes for a very short moment and is instantly covered by ADAP on the desk afterwards. WAITING is flickering on the PC.

4. All buttons at the control desk including the RESET button are inactive during adaptation. The only way to RESET an error is to release the PREP switch which causes an interrupt similar to the RESET command.

5. After letting go of the PREP switch wait until the desk indicates READY. If READY does not appear at least after 20 seconds run a warmstart of the generator by pushing the RESET button on CU EZ139.

6. If adaptation seems to do nothing for more than 30 seconds let go of the PREP switch. Wait until the desk indicates READY. If READY does not appear at least after 20 seconds run a warmstart of the generator by pushing the RESET button on CU EZ139.

7. If a constant READY indication appears for more than 2 seconds while PREP and EXP is activated by the handswitch during adaptation let go of the handswitch. Wait until the desk indicates READY. If READY does not appear at least after 20 seconds run a warmstart of the generator by pushing the RESET button on CU EZ139.

8. If adaptation does not carry on with or without READY indication check whether one of the function units indicates a FATAL error by turning on the red LED. Let go of the handswitch and run a warmstart of the generator by pushing the RESET button on CU EZ139.

9. If adaptation has been interrupted by a generator warmstart check the error log index before restarting adaptation: kV errors 02WG and/or 02WH indicate tube arcing. Run conditioning of the tube as described in chapter 8.3.1 and/or reduce the max. kV value to the required application value.

8.4.4. Fault exposure detection

Fault exposure detection is switched ON as a default for AEC and TDC. If in the initial phase of an exposure too little dose is measured, the exposure is aborted to protect the patient.

-- Time of control measurement: 10% of backup time,

min. 250ms at TDC

-- Dose minimum: 4% of set density voltage at AEC,

4 ... 10% at TDC

-- Backup time AEC: Calculated time from 9.5 times mAs of the respective 2-factor technique,

max. 4s

-- Backup time TDC: Exposure time set 0.3 ... 6s

This additional precaution can be switched OFF for both techniques individually in the menu: PROGRAM/ DOSE RATE CONTROL/ FAULT EXPOSURE DETECTION/ AECORTDC

For details see section “FAUL T FINDING”, chapter “Optimus AEC switch--OFF philosophy”.

This monitoring does not take effect in the following cases, irrespective of programming:

-- Using screen/film combinations with high speed in AEC technique.

-- Exposure time in TDC technique is shorter than 1s.

8.4.5. Continuous fluoroscopy

Factors for continuous fluoroscopy can be modified: (see also section 4 FAULT FINDING, “Explanation of programming”)

-- scantime TV [ms] : = 20.00ms (default) for scantime of the TV system ≤ 20ms (50Hz and 60Hz)

= Scantime of the TV system for scantime > 20ms

-- scantime TV valid : = YES default

= NO no function yet

-- P_max_EDL [W] : = 250W (default) (EDL = Entrance Dose Limiter)

(range = 0 ... 9000W) The maximum output of the tube during continuous fluoroscopy and with the SID

signal prevailing is limited to the programmed wattage. P_max_EDL [W] is only active if the DRLM (Dose Rate Limiter) signal on 1 WBX12:1 is active (see also Z1--15.2) For adjustment see section 6 ADJUSTMENTS.

-- TV_pos_limit [V] : = 6.8V (default) Adjustment necessary if the fluoroscopic image does not come up

properly.

8.5. Application limits

8.5.1. X--mode limits

Using the menu: PROGRAM/ APPLICATION LIMITS/ X-MODE LIMITS

Limit values can be defined for all available techniques. Some values look as if they are out of limit which they are indeed, but there are additional basic limit values programmed in the generator firmware. These are exposure technique dependent.

As an example the field of the ”Falling Load” technique:

X--ray Mode: AEC falling load kV

Min. Time Limit [ms]: [1.00] Max. Time Limit [ms]: [60000.00] Min. Current Time Product Limit [mAs]: [0.001] Max. Current Time Product Limit [mAs]: [580.000]

Min. Time Limit [ms]: Is always 1ms for all non--AEC (Automatic Exposure Control) techniques.

Exposures with AEC might be switched shorter than 1ms.

Max. Time Limit [ms]: Basic limits are technique dependent and can not be changed or increased:

AEC falling load kV 4000ms AEC fixed current kV--mA 4000ms TDC (Tomo Density Control) 6000ms

 kV--mA--ms 16000ms

free techniques  kV--mAs 16000ms

 kV--mAs--ms 16000ms

Min. Current Time Product Limit [mAs]: The smallest mAs -- product is 0.5mAs.

AEC exposures with less than 0.5mAs are possible.

Max. Current Time Product Limit [mAs]: The default mAs -- product is 580mAs for all AEC--techniques.

850mAs is the absolute limit the generator terminates.

Note

Local limits have to be taken into consideration.
