Instantaneous in vivo distal edge verification in intensity‐modulated proton therapy by means of PET imaging

open access: yesMedical Physics, EarlyView.
Abstract Background Intensity‐modulated proton therapy (IMPT) holds promise for improving outcomes in head‐and‐neck cancer (HNC) patients by enhancing organ‐at‐risk (OAR) sparing. A key challenge in IMPT is ensuring an accurate dose delivery at the distal edge of the tumor, where the steep dose gradients make treatment precision highly sensitive to ...

Characterization of a Commercial Ionization Chamber Array With Scanned Proton Beams for Applications in MRI‐Guided Proton Therapy

open access: yesMedical Physics, EarlyView.
Abstract Background The integration of MRI‐guidance and proton therapy is a current research topic. Proton therapy with the patient being placed inside an in‐beam MR scanner would require the presence of its static magnetic (B0$B_0$) field to be taken into account in dose calculation and treatment planning.

Characterizing diamond detectors for various dose and dose rate measurements in scanned carbon and oxygen beams

open access: yesMedical Physics, EarlyView.
Abstract Background The emerging FLASH radiotherapy technique employs “Ultra‐High Dose Rate” (UHDR) irradiations and offers the potential to spare normal tissue while maintaining iso‐effective tumor treatment. Given the physical and biological advantages inherent to high “Linear Energy Transfer” (LET) particles, the combination of UHDR and high LET has
