Using an external registration system for daily patient repositioning in protontherapy

Abstract: In this paper, we present an iterative method for positioning a patient in protontherapy. The main difficulty in this kind of treatment is the unknown position of the treated volume during the set up of the patient. The positioning process is realized by a 6 degrees of freedom (DOF) industrial robot. This article explains how the positioning error of the treated volume can e minimized thanks to an external tracking system.

“…A similar approach of correspondance between current fiducial markers orthogonal images and reference is found in [12], and can be applied in radio-surgery [13]. A refinement step can be provided by an infrared stereovision camera POLARIS that returns 3D locations of five reflecting ball implanted on the plastic mould [6]. Other patient alignment systems use image registration techniques based on skull image, or external markers detected in 3D with several infrared stereovision cameras [9], [8].…”
