Motion tracking of low‐activity fiducial markers using adaptive region of interest with list‐mode positron emission tomography

Autor: Marc J. P. Chamberland, Robert deKemp, Tong Xu

Publikováno v: Medical Physics. 47:3402-3414

PURPOSE Motion compensated positron emission tomography (PET) imaging requires detecting and monitoring of patient body motion. We developed a semiautomatic list-mode method to track the three-dimensional (3D) motion of fiducial positron-emitting mar

Technical aspects of real time positron emission tracking for gated radiotherapy

Autor: Tong Xu, Marc J. P. Chamberland, Malcolm McEwen

Publikováno v: Medical Physics. 43:783-795

Purpose: Respiratory motion can lead to treatment errors in the delivery of radiotherapy treatments. Respiratory gating can assist in better conforming the beam delivery to the target volume. We present a study of the technical aspects of a real time

Evaluation of the clinical efficacy of the PeTrack motion tracking system for respiratory gating in cardiac PET imaging

Autor: Tong Xu, Spencer Manwell, Robert A. deKemp, Marc J. P. Chamberland, Ran Klein

Publikováno v: Medical Imaging 2017: Physics of Medical Imaging.

Respiratory gating is a common technique used to compensate for patient breathing motion and decrease the prevalence of image artifacts that can impact diagnoses. In this study a new data-driven respiratory gating method (PeTrack) was compared with a

Performance evaluation of real-time motion tracking using positron emission fiducial markers

Autor: Benjamin Spencer, Marc J. P. Chamberland, Tong Xu, Richard Wassenaar

Publikováno v: Medical Physics. 38:810-819

Purpose: Tumor motion due to patient breathing is a factor that limits the accuracy of dose distribution in radiotherapy. One of the methods to improve the accuracy is by applying respiratory gating or tumor tracking. Both techniques require a precis
