3.2.3 RX EXPOSURE TIME

In the following tables the exposure times (s) associated to kV and mAs are reported. Since

the apparatus is a device functioning with a two point technique (kV and mAs) we remind that the

values indicated in the table are merely theoretical and can undergo a variation in relation to the

tolerance of the mA.

1 ROUTINE MAINTENANCE

1.1 GENERAL RECOMMENDATIONS

The radiological system requires regular checks and maintenance. The following

recommendations have the aim of helping the operator to keep the apparatus in good working and

safe conditions during service.

The system contains mechanical parts subject to wear according to use: following prolonged

use, wear on parts may decrease safety during use. For this reason, it is essential for the checking

and maintenance operations indicated below to be carried out consistently to protect the operators

and patients against any damage caused by mechanical breakdowns.

Correct adjustment of the electrical and electronic systems has a direct influence on the

operation of the system, on the quality of the image and on the electrical safety of the system, as

well as on the level of exposure to radiation the operators and patients are subjected to.

The M

and interventions to be carried out by specialised personnel authorised by the manufacturer. All

maintenance operations are the responsibility of the owner of the apparatus.

AINTENANCE PROGRAMME, described in the following paragraphs, consists of controls

Should it be necessary to replace components or parts which may in any way

condition the safety of the machine, only use original spare parts.

1.4 CLEANING AND DISINFECTION

Products with a high content of alcohol, corrosive and/or abrasive detergents or solvents must

not be used to clean the surfaces of the apparatus.

To disinfect the system, only use methods in compliance with the laws in force regarding

disinfection and protection procedures against explosion.

To carry out the cleaning and disinfection operations, take the following precautions:

 turn the system off and disconnect the mains power supply cable

 make sure that no liquid gets into the apparatus so as to avoid any short-circuits or

corrosion of the electrical and electromechanical parts.

The unit has not to be used in presence of anaesthetic and/or infiammable

disinfectant and cleaning products.

If, producing explosive gaseous, mixture, are used, make sure that gases are

dispersed before switching on the unit.

5.1 ADJUSTMENT OF FILAMENT CURRENT

NOTE: by Filament Current the current which runs through the primary winding of the

transformer supplying the power to the filament itself is intended (Coolidge Transformer).

EASUREMENTS

• To measure the Filament Current, connect an ammeter with true

RMS reading in series with terminal CP6-2 of board S15. Set

the full-scale to 1A in AC.

• to measure the anode mA in RADIOGRAPHY, connect the probe

of an oscilloscope between test points TP6 (+) and TP11 (-) of

board S19/B to display the wave form of the mA (reading

correspondence is 1V = 50 mA) and between test points TP3

(+) and TP11 (-) of board S19/B to display the wave form of

the kV (reading correspondence is 1V = 20 kV).

8 CHECKING THE RADIOGRAPHIC PARAMETER

After having completed the operations indicated in the previous paragraphs (§ 2, § 4, § 5), it is

necessary to check the values of the signals proportional to the kV and to the mA which come from

NVERTER. The tolerance for the kV signal is ± 5% whereas for the mA it is ± 15%.

the I

OTE: If the kV value is not correct, it is necessary to repeat the SET kV adjustment.

OTE: An oscilloscope with two channels is required for the checks below.

8.1 CHECKING KV AND mAs DURING RADIOGRAPHY

 Connect the probe of the oscilloscope as indicated below:

HANNEL A: TP3 (+) – TP11 (-) of board S19/B (REAL kV);

IME BASE: 10 ms

 If necessary, connect the probe of the oscilloscope as indicated

below:

HANNEL B: TP6 (+) – TP11 (-) of board S19/B (mA);

IME BASE: 10 ms

 set the minimum value of the kV (40 kV – 425 mA)

 give the X-

oscilloscope correspond with those indicated in T

RAY command and check that the values read on the

ABLE 6; (FIGURE

3 shows an example of a 100 kV wave form)

 repeat the previous operations, setting the kV values to 80 kV and

120 kV both for 15 kW and 7.5 kW powers.

10 SPRING ADJUSTMENT

The BALANCED SUSPENSION system of the mobile unit allows flowing movement of the ARM

vertically and, therefore, of the X-R

AY UNIT. This system has been studied and made to reduce the

need for maintenance to a minimum.

As time passes and due to the continual stresses, the balancing system may lose a very small

amount of its efficiency. It is usually sufficient to adjust the B

LUTCH DISKS (2); disassemble the arm carters for this operation (SEE 3 – MECHANICAL

OOM PIN (3) which acts directly on

ASSEMBLY AND DISMANTLING).
