Adaptive CaRdiac cOne BEAm computed Tomography (ACROBEAT): Developing the next generation of cardiac cone beam CT imaging.
Reynolds, Tess; Dillon, Owen; Prinable, Joseph; Whelan, Brendan; Keall, Paul; O'Brien, RickyPublished 2021Purpose: An important factor when considering the use of interventional cone beam computed tomography (CBCT) imaging during cardiac procedures is the trade-off between imaging dose and image quality. Accordingly, Adaptive ...Open AccessArticle -
Evaluating reconstruction algorithms for respiratory motion guided acquisition
Dillon, Owen; Keall, Paul; Shieh, Chun-Chien; O'Brien, RickyPublished 2020Conventional thoracic 4DCBCT scans take 1320 projections over 4 min. This paper investigates which reconstruction algorithms best leverage Respiratory-Motion-Guided (RMG) acquisition in order to reduce scan time and dose ...Open AccessArticle -
The first-in-human implementation of adaptive 4D cone beam CT for lung cancer radiotherapy: 4DCBCT in less time with less dose.
O'Brien, Ricky; Dillon, Owen; Lau, Benjamin; George, Armia; Smith, Sandie; Wallis, Andrew; Sonke, Jan-Jakob; Keall, Paul; Vinod, ShaliniPublished 2021Background and purpose: We present the first implementation of Adaptive 4D cone beam CT (4DCBCT) that adapts the image hardware (gantry rotation speed and kV projections) in response to the patient's real-time respiratory ...Open AccessArticle -
Toward improved 3D carotid artery imaging with Adaptive CaRdiac cOne BEAm computed Tomography (ACROBEAT)
Reynolds, Tess; Dillon, Owen; Prinable, Joseph; Whelan, Brendan; Keall, PaulPublished 2020Purpose: Interventional treatments of aneurysms in the carotid artery are increasingly being supplemented with three-dimensional (3D) x-ray imaging. The 3D imaging provides additional information on device sizing and stent ...Open AccessArticle
