3.2.7.6 Pendulum Mode, Table
General Description
The Pendulum mode can be seen as a variation of film tracking.
The X-ray tube is always aimed at the center of the detector. The alpha angle of the tube and
the position of the detector changes according to the change in X-position of the tube stand.
Also Pendulum mode incorporates all the functionality of the more simple Table mode. The
mode is intended for fast and easy positioning with the X-ray tube always aimed at the center
of the detector.
For moving and controlling the position of the detector, a motorized detector holder is re-
quired. The stand will upon activation of the servo button move to the programmed position
associated with the Pendulum mode and start tracking the Table height, thereby keeping the
film focus distance constant.
All table handle bar buttons, except (move left) and (move right) buttons, will be deactivated
when the Pendulum mode is activated. The X-position of the stand is controlled by these two
buttons and thereby also the detector and the alpha angle of the tube.
Exposure Validation
Exposure is allowed if the stand is not moving, operating properly (not in an error state), the
X-ray tube is aimed to the center of the detector and the servo button is activated.
