About Initialization Axes are initialized on machine restart after the system is shut down (for example, due to machine servicing or an emergency stop). The system performs many axis initialization routines automatically. You can also perform some axis initialization operations manually inside the treatment room, using the Service application on the in-room computer and a pendant.
Axis initialization involves setting up equipment and then using the Initialization Assistant wizard to initialize axes, including the: Collimator. X1, X2, Y1, and Y2 jaws. Multileaf collimator. kV and MV imagers. Other machine axes.
Prerequisites for Initializing Axes Before initializing axes, make sure that: · The gantry is in the head up position (0° in IEC1217 and VarianIEC display scales; 180° in Varian display scale). · The couch longitudinal axis is fully extended. To move machine axes away from the gantry before starting initialization, use a pendant.
Testing Motor Driver Force and Speed MLC Motor Driver tests consist of PWM and Velocity tests. The PWM test measures the average driving force (pulse width) that can drive a leaf with a speed of 1 mm per second. The Velocity test drives the MLC leaves with constant PWM and velocity computed from sampled positions over known intervals; velocity is expected to be constant. The degradation (increase) of the pulse width value or variation in velocity for any given leaf over time indicates increasing resistive force on the leaf due to bent parts, adjacent leaves that are touching, direct accumulation, or some other cause.
