Step 140, the first Motor drive X-ray machine platform of control move to operating position on the first guide rail；Also, control
Second Motor drive detector platform moves to operating position on the second guide rail.
After X-ray machine platform, detector platform and filtering frame are installed, need first to adjust X-ray machine platform and detector platform
Save to operating position.Specifically, the first motor receives the first displacement signal, drives the leading screw on the first guide rail to rotate, drives silk
On thick stick, the first slide block is along guide screw movement to operating position, so as to drive X-ray machine platform to move to operating position on the first guide rail；
Then, the second motor receives second displacement signal, drives the leading screw on the second guide rail to rotate, and on drive leading screw, the first slide block is along silk
Thick stick moves to operating position, so as to drive detector platform to move to operating position on the second guide rail.Wherein, the first displacement letter
Number and second displacement signal can be sent by computer control system by operating personnel.
Step 150, adjusts the position of X-ray machine platform, and adjustment filters frame, makes the X-ray Exit positions of X-ray machine, filters on frame
The reception X-ray position of the additional filterings piece center of grafting and detector is on the same line.
Wherein, step 150 is divided into two parts and is adjusted, and Part I is the position for adjusting X-ray machine platform, makes X-ray machine
X-ray Exit positions and detector reception X-ray position on the same line；Part II is adjustment filtering frame, makes X-ray machine
X-ray Exit positions and filtering frame on grafting additional filterings piece center on the same line so that the X-ray outgoing of X-ray machine
On position, filtering frame, the reception X-ray position of the additional filterings piece center of grafting and detector is on the same line.
Part I is described below：
First, the laser calibrator on X-ray machine platform is opened, launches laser；Wherein, laser calibrator is arranged on X-ray machine
On the pitching platform of platform, the exit direction of laser is identical with the direction of X-ray machine exit Xray bundle.
