2 C-Arm Software
LOADING APPLICATION SOFTWARE
Application software is by entered utilizing the operating system or from a program such
as STATUS. The key events which occur are:
1. Technique Processor PCB EEPROM (U20) is checked.
2. Default Fluoro and Film parameters are loaded and the system is configured by the
OPTIONS.DAT file. Options such as Boost and 40 mA pulsed mode are initialized.
3. The 40 kHz clock on the Analog Interface PCB is started.
4. Hardware is again initialized as a precaution.
5 The MALIMIT.DAT file and ABS tables are loaded.
6. Tests are run to determine if the system is capable of functioning.
7. Footswitch is checked (for "footswitch stuck" fault).
8. Generator Interlock (+24V) is made.
9. Capacitors C2 and C3 on Generator Controller Assembly are charged by Battery B+
voltage through pre-charge circuitry.
10. The stator line is pulsed.
11. Check for disconnected batteries and check B+ voltage.
12. The small filament is preheated.
13. Generator and X-ray tube control signals are initialized.
14. Heat units are computed for the anode and housing.
15. If no problems are found, operator input is accepted from the control panel.
PERIODIC FUNCTIONS AND ACTIONS
These are functions executed periodically by the software program, which include
Control Panel Processor PCB polling and error checking. Items checked include:
1. X-ray tube heating.
2. Battery voltage and current.
3. Hardware faults - such as overloads, saturation, and filaments, stator, collimator,
HV inverter, interlocks, communications to Image Function PCB and Control Panel
Processor PCB.
