4.7 X-ray Table Examination Procedures

4.7.1 Table Flexible Mode

4.7.1.1 General

The

Table Flexible mode

is designed for examinations with the detector placed on the table

top.

The OTC can be moved freely in all directions. When the height of the table top is adjusted,
the OTC will track the height of the table top in order to keep the SID constant.

4.7.1.2 Flow of Operation

Select a

Table Flexible mode

examination.

The System display will show the following.

Fig. 4-9 Table Flexible mode display

• The SID will be displayed.
Activate the mode by pressing the servo button.
• The OTC will automatically move to its programmed position.
• The OTC will move to the programmed SID.
• Servo mode indication light fixed.
Adjust the table height.
• The OTC will follow the Table to maintain the programmed SID.
Adjust the tube position.
• The mode will stay activated (detector holder will not follow).
• Move the imaging unit manually, if needed, to assure that the x-ray field is inside the boun-

daries of the detector.

4.7.1.3 Exposure

Exposure is possible when the OTC is not moving, and the servo mode indication light is
fixed.

CAUTION!

Materials located in the X-ray beam may cause adverse image effects.

Note!

In “Table Flexible mode” examinations exposure is possible outside the imaging unit.

The imaging unit does not follow the OTC.
