Several recent developments in linear accelerator–based radiation therapy (RT) such as fast
multileaf collimators, accelerated intensity modulation paradigms like volumeric modulated …

Abstract Aims and Methods: Delivery of high radiation doses while simultaneously sparing
organs at risk requires advanced imaging for target volume definition, highly conformal dose …

The use of Cone-beam Computed Tomography (CBCT) in radiotherapy is increasing due to
the widespread implementation of kilovoltage systems on the currently available linear …

The fusion of the fast growing fields of imaging science, imaging hardware, and
computational modeling, together with a broad interest in learning more about respiratory …

Hypofractionated image-guided stereotactic ablative radiotherapy (igSABR) is effective in
small lung/liver lesions. Computer-assisted breath-hold reduces intrafraction motion but, as …

Purpose Medical imaging is an indispensable tool in radiotherapy for dose planning, image
guidance and treatment monitoring. Cone beam CT (CBCT) is a low dose imaging …

Objective. The concept of using kilovoltage (kV) and megavoltage (MV) beams concurrently
has potential applications in cone beam computed tomography (CBCT) guided radiation …

Volumetric modulated arc therapy (VMAT) is a relatively new treatment modality for dynamic
photon radiation therapy. Pre-treatment quality assurance (QA) is necessary and many …

BACKGROUND AND PURPOSE: Acquisition of cone-beam CT (CBCT) concurrent with
VMAT results in scatter of the megavoltage (MV) beam onto the kilovoltage (kV) detector …

Image-guided radiotherapy (IGRT) has helped to dramatically reduce safety margins
compensating for positioning uncertainties in radiotherapy. A remaining issue posing …
