DOI: 10.1002/acm2.12160
Abstract: Abstract The accurate delivery of respiratory‐gated volumetric modulated arc therapy (VMAT) treatment plans presents a challenge since the gantry rotation and collimator leaves must be repeatedly stopped and set into motion during each breathing cycle.… read more here.

DOI: 10.1002/mp.17749
Abstract: Respiratory motion poses a critical challenge in small animal lung imaging with micro‐computed tomography (µCT). Contact sensors, when utilized as respiratory gating devices, can introduce beam‐hardening artifacts and degrade image quality. read more here.

DOI: 10.1117/1.jmi.10.1.016002
Abstract: Abstract. Purpose We hypothesize that in vivo respiratory-gated micro computed tomography (micro-CT) imaging can noninvasively provide structural and functional information about the lungs in a cigarette-exposure model of chronic obstructive pulmonary disease in mice. Approach… read more here.

DOI: 10.1186/s13550-025-01195-w
Abstract: Device-based respiratory gating improves diagnostic and quantification accuracy in positron emission tomography (PET), but requires additional time to setup the device and the failure rate can be significant. Our aim was to internally validate the… read more here.
