Registration of pre-and intra-interventional data is one of the key technologies for image-
guided radiation therapy, radiosurgery, minimally invasive surgery, endoscopy, and …

Radiotherapy (RT) aims to deliver a spatially conformal dose of radiation to tumours while
maximizing the dose sparing to healthy tissues. However, the internal patient anatomy is …

Purpose: To report the clinical experience with an electromagnetic treatment target
positioning and continuous monitoring system in patients with localized prostate cancer …

New technologies continue to be developed to improve the practice of radiation therapy. As
several of these technologies have been implemented clinically, the Therapy Committee …

Dose escalated radiotherapy improves outcomes for men with prostate cancer. A plateau for
benefit from dose escalation using EBRT may not have been reached for some patients with …

Background and purpose Interfraction volumetric changes/rotations in the prostate and
proximal seminal vesicles (SVs) might compromise target coverage when tight margins are …

PURPOSE: To evaluate the effect of rectal distention on the planning computed tomogram
on freedom from biochemical failure (FFBF) of prostate cancer patients treated with image …

Purpose: The aim of this work was to study the variations in delivered doses to the prostate,
rectum, and bladder during a full course of image-guided external beam radiotherapy …

PURPOSE: To determine planning target volume (PTV) margins for prostate radiotherapy
based on the internal margin (IM)(intrafractional motion) and the setup margin …

Purpose: The use of intraprostatic fiducials as surrogates for prostate gland position
assumes that the markers are rigidly positioned within the prostate. To test this assumption …
