Quality assurance for image-guided radiation therapy utilizing CT-based technologies: a report of the AAPM TG-179.

Journal article Med Phys · April 2012 Featured Work PURPOSE: Commercial CT-based image-guided radiotherapy (IGRT) systems allow widespread management of geometric variations in patient setup and internal organ motion. This document provides consensus recommendations for quality assurance protocols that ensu ... Full text Link to item Cite

Preoperative single fraction partial breast radiotherapy for early-stage breast cancer.

Journal article Int J Radiat Oncol Biol Phys · January 1, 2012 Featured Work PURPOSE: Several recent series evaluating external beam accelerated partial breast irradiation (PBI) have reported adverse cosmetic outcomes, possibly related to large volumes of normal tissue receiving near-prescription doses. We hypothesized that deliver ... Full text Link to item Cite

Impact of volumetric modulated arc therapy technique on treatment with partial breast irradiation.

Journal article Int J Radiat Oncol Biol Phys · September 1, 2010 Featured Work PURPOSE: To investigate the technical feasibility of volumetric modulated arc therapy (V-MAT) in the delivery of partial breast irradiation (PBI). METHODS AND MATERIALS: V-MAT and the standard, three-dimensional conformal radiotherapy (3D-CRT), were compar ... Full text Link to item Cite

Radiotherapy treatment plans with RapidArc for prostate cancer involving seminal vesicles and lymph nodes.

Journal article Int J Radiat Oncol Biol Phys · March 1, 2010 Featured Work PURPOSE: Dosimetric results and treatment delivery efficiency of RapidArc plans to those of conventional intensity-modulated radiotherapy (IMRT) plans were compared using the Eclipse treatment planning system for high-risk prostate cancer. MATERIALS AND ME ... Full text Link to item Cite

Clinical evaluation of positioning verification using digital tomosynthesis and bony anatomy and soft tissues for prostate image-guided radiotherapy.

Journal article Int J Radiat Oncol Biol Phys · January 1, 2009 Featured Work PURPOSE: To evaluate on-board digital tomosynthesis (DTS) for patient positioning vs. two-dimensional (2D) radiography and three-dimensional cone beam (CBCT). METHODS AND MATERIALS: A total of 92 image sessions from 9 prostate cancer patients were analyzed ... Full text Link to item Cite

Assessment of the residual error in soft tissue setup in patients undergoing partial breast irradiation: results of a prospective study using cone-beam computed tomography.

Journal article Int J Radiat Oncol Biol Phys · March 15, 2008 Featured Work PURPOSE: On-board cone-beam computed tomography (CBCT) provides soft tissue information that may improve setup accuracy in patients undergoing accelerated partial breast irradiation (APBI). We used CBCT to assess the residual error in soft tissue after two ... Full text Link to item Cite

Dosimetric feasibility of cone-beam CT-based treatment planning compared to CT-based treatment planning.

Journal article Int J Radiat Oncol Biol Phys · December 1, 2006 Featured Work PURPOSE: Cone-beam computed tomography (CBCT) images are currently used for positioning verification. However, it is yet unknown whether CBCT could be used in dose calculation for replanning in adaptive radiation therapy. This study investigates the dosime ... Full text Link to item Cite
