Abstract
Most of the setup verification systems employed in radiotherapy treatments use ionizing radiation to visualize bone structures. Alternatively external body surfaces can be acquired with optical systems that, due to the absence of any additional radiation exposure, are interesting solutions for daily repositioning checks The aim of this work is to investigate the performances of Sentinel a laser/camera surface imaging system, when used on patients treated in pelvic and thoracic regions. The system accuracy was evaluated comparing registrations results from concurrent Sentinel and CBCT acquisitions.
