SID SENSOR AND BRACKET LOCATIONS
Use of Longitudinal and Transverse Detents
The suspension is equipped with Longitudinal and Lateral detents to
automatically apply the locks and signal the collimator when the tube is
positioned at specific SID’s, for vertical table or wall stand procedures. The locks
are actuated through SID detent sensors that ride along the bridge and stationary
rails, and detect coded brackets set at pre-determined locations. For table, lateral
detent is set at the table lateral centerline. For wall stand, lateral detent is set at
the wall stand panel lateral centerline, and the longitudinal detent is set at SID
180cm(72 inches) and 100cm(40 inches). Selection is made at the time of
installation and is usually with the focal spot over the longitudinal table and wall
stand centreline. The locks are actuated through electrical detents and the switch
marked DETENT. Depress the “DETENT” switch and the “LAT” switch to index
the focal spot over the longitudinal table centerline. Depress and momentarily
hold the “LONG” switch (with the “DETENT” switch still depressed) to index the
focal spot at one of the pre-selected SID’s. When reaching the approximate
position, motion should be slow to avoid passing over the detent bracket. To
move out of the indexed positions, depress the “DETENT” switch a second time.
Note:
The longitudinal and lateral locks are the electromagnet type and are “off”
when the power is off. They are applied when the power is on and their
switches are in the upper position (not depressed). To release the locks,
depress the switches.
Use of Vertical Detent
There is a vertical detent switch in the Overhead Tube Suspension column that
will set the locks when the tube reach the pre-set distance, such as 100cm (40
inches) above the film. Depress the “DETENT” switch and the “VERT” switch to
index the focal spot at the 100cm (40 inches) SID.
Note:
This function doesn’t apply to tube angulation radiography.
