Installation of first 'Cone-Beam CT' on linear accelerator

By Aswin Hoffmann on 03 September 2009

From July 1st onwards, the department has a Cone-Beam CT scanner on one of the linear accelerators.

Before the start of irradiation, patients are positioned as accurately as possible on the linear accelerator aiming at optimally treating the tumor and sparing as much healthy tissue as possible. Generally, this positioning is conducted using an x-ray camera that facilitates the projection of bony structures on a flat panel. With the new Cone-Beam CT, it is possible to acquire an image in three directions (as a volume) and to also display other structures than bone. By this means, more information for specific situations is available resulting in more accurate patient positioning.
