12. PET range verification in proton therapy (research at U. Sevilla and CNA)

Carlos Guerrero Sanchez (Universidad de Sevilla (ES))

Oral contribution

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...

21. On-the-fly reconstruction of activation by proton beams using in-beam PET

Oral contribution

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...

19. A dedicated dual-head TOF-PET system for in-vivo quality control of beam delivery in proton therapy

Pedro Arce (CIEMAT - Centro de Investigaciones Energéticas Medioambientales y Tec. (ES))

Oral contribution

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...

13. Hybrid Compton-PET imaging for ion-range monitoring in hadron therapy

Cesar Domingo Pardo (Univ. of Valencia and CSIC (ES))

10/05/2023, 16:10

Oral contribution

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...
