ILLUSTRATION 7-6
X-RAY TUBE ANGULATION
The other rotational feature of the tube
support permits TUBE ANGULATION
about the short axis (front to back). The
amount of angulation is indicated on the
user interface. Limits of angulation are
180° in either direction from the X-ray
beam down position. The angulation
lock that is controlled by the switch
marked ANG maintains angular
positions. while angulating the tube.
Angular positions will detent every 90°
automatically starting with the X-ray
beam down position. To move out of a
detent position, depress the ANG button
and hold this switch down, rotating the
tube assembly. Release the button to
lock the tube in place.
Note: Angulation lock is the Electro Magnetic, spring applied, type. They remain
“on” when the system power is off. They can be released only when the
power is on and their respective switches are depressed. In emergencies,
the tube unit can be moved against the force of the locks.
The gravity center of the angulating parts (including tube, OTS console,
collimator, etc.) is lower than the angulating axis. So when tube angulation
is 90 degree, if release the angulation lock, there will be a trend of tube to
angulate downward.
When tube angulation is 90 degree, please pay attention to hold the OTS
console with both arms as release the angulation lock.
Note: When taking exposure with the Wall Stand (GPCP No. 2260354) or SG120
Wall Stand (GPCP No. 2402562), if the Wall Stand or SG120 Wall Stand is
mounted to the side of the Table (C or D in the illustration below), the X-ray
tube should only be angulated anticlockwise and not be angulated
clockwise.
When angulated anticlockwise, the position of the X-ray tube Anode is
lower than angulated clockwise, so the heat dissipation performance of the
tube is distinctively better than angulated clockwise.
