This paper describes a patient positioning method that allows a non-invasive localization of tumors in the field of conformal radiotherapy for the treatment of cancers located in the head. The proposed methodology uses computer tomography and range sensor images of the patient's head; on the one hand tomography data has information of tumor localization related to the patient's head and on the other...
The use of 3D surface sensor has been recently proposed for patient positioning in radiotherapy treatments. In this kind of applications, relating the coordinate system of 3d sensor with the coordinate system of treatment's room is crucial and needs a sensor's calibration. Sensor's calibration depends of its measuring principle; so calibrating a time-of-fly sensor has some differences to calibrating...
