Deep learning‐based upsampling of 2D detector array measurements for patient plan verification in radiotherapy

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Detector arrays are commonly used for treatment plan verifications in intensity modulated radiation therapy. However, the intrinsic resolution of detector arrays is limited by the physical dimensions of each single detector and the detector‐to‐detector distance.

Multileaf Faraday cup for beam energy verification in radiation therapy with ultra‐high dose‐rate electron beams and ion beams

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background In radiotherapy and particle therapy, the stability of the beam energy must be checked routinely during quality assurance. This is of particular importance when varying the dose rate via the beam intensity of the accelerator in order to study the FLASH effect when comparing irradiations with conventional and ultra‐high dose rates ...

Influence of radiotherapy dose rate on gold nanoparticle‐induced radiosensitization from high dose‐rate brachytherapy and external beam therapy

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Associated normal tissue toxicity from current radiotherapy (RT) treatments limits effective dose escalation in the tumor to achieve nominal treatment results. Gold nanoparticles (GNPs) as radiosensitizing agents to locally increase photoelectron production have gained interest as a safe and viable method to improve therapeutic ...

Revisiting the segmentation threshold for Lu‐177 SPECT

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background The mostly used threshold‐based segmentation method for SPECT, i.e., 42% of the maximum intensity, was derived from 99mTc and may not be directly applicable to 177Lu. Purpose This study aims to revisit the optimal segmentation threshold for 177Lu SPECT.
