Abstract:
Positioning a patient accurately in treatment devices is crucial forradiological treatment, especially if accuracy vantages of particlebeam treatment are exploited. To avoid sub-millimeter misalignments,X-ray images acquired from within the device are compared to a CTto compute respective alignment corrections. Unfortunately, deviationsof the underlying geometry model for the imaging system degrade theachievable accuracy. We propose an automatic calibration routine,which bases on the geometry of...     »
