T: Treatment Monitoring
- Paulo Crespo (LIP)
In proton therapy, Positron Emission Tomography (PET) range verification, which is based on the detection of the short-lived (online monitoring) or the long-lived (offline monitoring) β+ emitters produced in the body of the patient, has been proved to be a well-suited technique to monitor the beam range. This technique requires the comparison of the observed activity distribution with Monte...
Introduction: In-beam PET is attractive in terms of feedback-time of treatment quality in protontherapy. However, it is challenged by the high rates produced during the beam-on period. In this work, we report the first results using a novel in-beam portable PET system that can detect and process on-the-fly the β$^+$ activity produced during and after irradiation.
Methods: The specific PET...
We are developing a prototype dual-head time-of-flight (TOF)-PET system for in-vivo verification of beam delivery in proton therapy. Such a system will allow PET image acquisition shortly after irradiation, profiting from imaging of short-lived O-15 and reduced biological washout effects, whereas TOF-PET reduces image degradation due to incomplete acquisition of projection data from the planar...
In this contribution I will present a summary of the research that we are doing at the Gamma-Ray Spectroscopy and Neutrons Group of IFIC (CSIC-UV) aimed at developing a new gamma-ray imaging methodology for enhanced accuracy ion-range verification in hadron-therapy treatments.
Two of the most promising methodologies for in-room real-time ion-range monitoring are positron-emission tomography...
