21. First Voxel-wise Prediction of Post-therapy Dosimetry for 177Lu-PSMA I&T Therapy

Song XUE (Dept. Nuclear Medicine, University of Bern, Switzerland)

Introduction:
PSMA-directed radioligand therapy (RLT) has become one of the effective treatment options for metastatic castration-resistant prostate cancer (mCRPC). However, individual treatment planning is still not feasible as it is for the external beam radiotherapy. Our group has presented the first organ-based research in the prediction of post-therapy dosimetry in SSRMP 2018. However,...

8. EPR dosimetry in the radiotherapy dose range using a benchtop spectrometer: Dose uncertainties for alanine and lithium formate dosimeters.

Mr Sebastian HÖFEL (Department of Chemistry and Konstanz Research School Chemical Biology, University of Konstanz, Germany)

Oral

Introduction
In electron paramagnetic resonance (EPR) dosimetry, water equivalent dosimeter materials such as alanine (Al) or, more recently, lithium formate monohydrate (LFM) featuring low fading rates (a few percent per year) and a linear dose response are typically used. The dependency of the dosimeter response on beam energy, dose rate and beam angle is usually negligible for therapeutic...

36. Dosimetric procedures for FLASH-RT biological experiments

Patrik JORGE (IRA)

Oral

Introduction
Recently, some of the established concepts governing the effects of radiation on healthy tissues were questioned by a new treatment modality using ultra-high dose-rates called FLASH radiotherapy (FLASH-RT). To this day, no metrological traceability for FLASH-RT dosimetry exists and no monitoring instruments can determine on-line the delivered dose during biological experiments....
