Optical surface information‐based respiratory phase‐sorting and motion‐incorporated reconstruction for SPECT imaging

Medical Physics, EarlyView.
Abstract Background Respiratory motion during the single photon emission computed tomography (SPECT) acquisition can cause blurring artifacts in the reconstructed images, leading to inaccurate estimates for activity and absorbed doses. Purpose To address the impact of respiratory motion, we utilized a new optical surface imaging (OSI) system to extract

Accuracy of a helium‐beam radiography system based on thin pixel detectors for an anthropomorphic head phantom

Medical Physics, EarlyView.
Abstract Background Ion‐beam radiography is a promising technique to verify the range of ion‐beam radiotherapy treatments regularly. To detect and quantify the water‐equivalent thickness (WET) of potential anatomical changes, ion‐beam radiographs must provide a sufficient WET accuracy on the level of 1%.

Verification of dose and dose rate for quality assurance of spread‐out‐Bragg‐peak proton FLASH radiotherapy using machine log files

Medical Physics, EarlyView.
Abstract Background Ultra‐high dose rate radiotherapy elicits a biological effect (FLASH), which has been shown to reduce toxicity while maintaining tumor control in preclinical radiobiology experiments. FLASH depends on the dose rate, with evidence that higher dose rates drive increased normal tissue sparing.

Out‐of‐field neutron radiation from clinical proton, helium, carbon, and oxygen ion beams

Medical Physics, EarlyView.
Abstract Background In hadron therapy, out‐of‐field doses, which may in the long‐term cause secondary cancers, are mostly due to neutrons. Very recently, 4He and 16O beams have been added to protons and 12C ions for clinical therapy. Purpose The focus of this article is to compare secondary neutron doses produced by clinical protons, 4He, 12C, and 16O ...
