In computer vision and image analysis, image registration between 2D projections and a 3D
image that achieves high accuracy and near real-time computation is challenging. In this …

Intra-fractional respiratory motion during radiotherapy leads to a larger planning target
volume (PTV). Real-time tumor motion tracking by two-dimensional (2D)/3D registration …

Purpose: The authors combine the registration of 2D beam's eye view (BEV) images and 3D
planning computed tomography (CT) images, with relative, markerless tumor tracking to …

In image-guided radiotherapy (IGRT) of disease sites subject to respiratory motion, soft
tissue deformations can affect localization accuracy. We describe the application of a …

This study demonstrates the feasibility of automated marker tracking for the real-time
detection of intrafractional target motion using noisy kilovoltage (kV) X-ray images degraded …

Intra-fractional respiratorymotion during radiotherapy is one of themain sources of
uncertainty in dose application creating the need to extend themargins of the planning target …

Radiation therapy (RT) planning in prostate cancer typically uses both CT images and T2-
weighted MR images, for dose calculations and treatment volume delineation, respectively …

Recent C-arm systems used for endovascular image-guided interventions enable the
acquisition of three-dimensional (3D) and dynamic two-dimensional (2D+ t) images in the …
