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 -
Innovative applications of kilovoltage imaging in image -guided lung cancer radiotherapy
Shieh, Chun-ChienPublished 2015-12-09Radiotherapy is one of the most efficient and cost-effective treatments of cancer. To ensure accurate radiation delivery, there is a need for image guidance technologies to monitor tumor motion during radiotherapy treatment. ...USyd AccessThesis -
A real-time IGRT method using a Kalman filter framework to extract 3D positions from 2D projections.
Nguyen, Doan Trang; Keall, Paul; Booth, Jeremy; Shieh, Chun-Chien; Poulsen, Per; O'Brien, RickyPublished 2021Purpose.To estimate 3D prostate motion in real-time during irradiation from 2D prostate positions acquired from a kV imager on a standard linear accelerator utilising a Kalman filter (KF) framework. The advantage of this ...Open AccessArticle
