Early Validation of ExacTrac Dynamic: New Features & Accuracy of the System


Jens Peter Bangsgaard, PhD, Head of Physics at Rigshospitalet, Copenhagen, Denmark, shares his early validation experiences of ExacTrac Dynamic including an introduction the patient positioning and monitoring system’s new features as well as its accuracy. He begins by giving a general introduction to ExacTrac Dynamic: Its tracking (surface and X-Ray), immobilization, calibration and phantoms. He also shows the workflow from setup to positioning and referencing to monitoring. Finally, he compares the accuracy of ExacTrac with cone beam CT (CBCT) as well as surface versus X-Ray tracking.

This is [inaudible 00:00:01.695]. And why you're looking at this nice guy here in the bottom, one with the thermal camera image and another one with the data camera system from the Dynamic system. I was just saying that the ExacTrac Dynamic system is still a work in progress. And therefore, we have not been using it on patients, but on phantoms alone. And just an overview of my institution and my radiation therapy in Denmark. We're quite a big department with 10 LINACs. Eight of them has ExacTrac, one have the nonclinical Dynamic system installed. Three are 6.5, and...
