4.5 Motion Limit Checks

4.5.1

Introduction

If – for some reason – there is doubt whether the motion system is correctly calibrated, it is rec-
ommended that you follow the procedures described in this section before starting to recalibrate
the system.
4.5.2

Verifying Absolute Encoder Calibration

Procedure
1. Move the detector to the patient load posi-
tion (horizontal 489 +/– 1 mm, vertical
371 mm, angle 90.0°).
2. If the detector angle read-out on the acqui-
sition PC is not 90.0º, use the hand con-
troller to fine adjust until you obtain this
reading.
Detector 1 must be vertical and detector 2
horizontal (within 0.1°) – check with a level.
3. If the detector vertical position read-out on
the acquisition PC is not 371 + 1 /– 0 mm,
use the hand controller to obtain this read-
ing.
4. Measure the free travel range for detector
movement in the tower opening.
This is the distance between the top of the
detector arm where it enters the hole in the
tower, and the top of the hole. The measured
value must be 832 mm +/– 1 mm.
