An Image Registration-Based Motion Correction Procedure to Recover Joint Cardiac and Respiratory Motion from Respiratory 4DCT

Authors: Phillip Cuculich, Geoffrey D. Hugo, Xiwen Li, Michael T. Prusator, Clifford Robinson, Pamela Samson, Xue Wu

Affiliation: Washington University School of Medicine in St Louis, Washington University School of Medicine in St. Louis, University of Utah, WashU Medicine

Abstract Preview: Purpose: Stereotactic arrhythmia radiotherapy (STAR) requires compensation for both respiratory and cardiac motions of the heart. Respiratory 4DCT scans implicitly include cardiac motion and cycle-to-...

Commissioning of a Near Real-Time In Vivo Film Dosimetry System

Authors: Maria F. Chan, Indra J. Das, Xiuxiu He, Seng Boh Gary Lim, Jeonghoon Park, Yunjie Yang

Affiliation: Department of Medical Physics, Memorial Sloan Kettering Cancer Center, Northwestern Memorial Hospital, Northwestern University Feinberg School of Medicine, Memorial Sloan Kettering Cancer Center

Abstract Preview: Purpose: There is a need for accurate and flexible in-vivo dosimetry systems, particularly for special procedures. Effective dosimetry is crucial for dose verification and maintaining records. A new r...

Image Guidance for Mitigating the Impact of Table Walkout on Delivered Dose in Non-Coplanar Stereotactic Radiotherapy

Authors: William E Burrell, Philip F. Durham, Anne N Hubbard, Yohan Akeakamai Walter, Hsinshun Terry Wu

Affiliation: Willis Knighton Cancer Center

Abstract Preview: Purpose: Linear accelerator (LINAC)-based single-isocenter, multi-target (SIMT) treatment has streamlined the stereotactic radiosurgery (SRS) workflow. However, off-isocenter treatment carries multipl...
