Press the key again to activate the next possible combination.
If the LED in the start key flashes,
◆ press the key.
– The compression device moves into park position, if present.
– The tube assembly stand moves into the 0° position.
– A source-image intensifier distance of 115 cm is set.
– The image receptor unit moves into the tomographic area.
Once the positions are reached, the flashing LED goes out.
Tomographic area If you have positioned the image receptor unit outside the tomographic area, it is
moved automatically when you press the start key so that tomography can be
performed with the required tomographic sequence. In this case the tabletop is
moved automatically synchronously to the image receptor unit.
Tomographic sequence
◆ Press the exposure release button up to the first pressure point.
– The tube assembly stand moves to the head-end tomography starting posi-
tion (at the left with the unit horizontal).
◆ Give the breathing command to the patient.
◆ Press the exposure release button all the way down and hold pressed until the
tube assembly stand stops.
– During the exposure the tube assembly stand moves towards the foot end
and automatically remains there following the exposure.
Prepare the next tomographic exposure:
◆ Set a new tomographic height.
◆ Press the exposure release button up to the first pressure point.
– The tube assembly stand moves from the foot-end position towards the
head-end tomography starting position (at the left with the unit horizontal).
Start
In the case of low-absorption objects with a water value below 10 cm (e.g. pe-
diatrics, upper/lower extremities) either fluoroscopy must be performed before
tomography or a Cu additional filter of at least 0,1 mm must be moved into the
beam path. Otherwise exposures may be overexposed or interrupted and there-
fore useless.
With the exposure release button pressed, the tube assembly stand moves back
into the starting position.
