Acquiring Images
Note: For more detailed information on how to perform X-ray Image Acquisition,
refer to the adaPTinsight documentation listed in the chapter “About this Manual.
Depending on the TR hardware configuration, 2D stereoscopic images are acquired
at the time of treatment using either one (rad-A) or multiple imaging devices (rad-A,
rad-B). Equally, 3D images can be obtained using a single 2D imaging device that
rotates around the volume to be imaged (CBCT Rad-B X-ray tube). 3D images are
then reconstructed using the acquired 2D images and the associated spatial
information (angle of acquisition).
The adaPTinsight application supports different acquisition modes in a TR depending
on the treatment room’s hardware configuration. The configuration of treatment
rooms at your center support:
kV CBCT (3D): in this mode, a sequence of 2D images is acquired using the Rad-
B X-ray tube. This sequence of images is then reconstructed by adaPTinsight
into a 3D image.
Perform the procedure that is applicable to your treatment room:
GTR: refer to section "Working with X-ray Images in a GTR, for Use With
adaPTinsight" on page 10-11.
After successfully completing the procedure that is applicable to your treatment
room, proceed as follows:
1. Start up X-ray generator(s), if not already started (refer to section “Starting the
X-ray Generators”on page 47-3).
2. From the ADAPTinsight WORKFLOW SELECTION SCREEN (see Figure 47-2), select
the appropriate workflow for the desired image acquisition mode, if not sent
automatically
Important As a Radiation Therapy Technologist (RTT), pre-position the patient
using lasers. During this process, pay attention to the potential large
difference between the position of isocenter indicated by the lasers and
the position of isocenter indicated by the x-ray image guidance system.
Such a large difference would indicate that one of these systems needs
to be re-aligned.
