American Brachytherapy Society consensus guidelines for high-dose-rate prostate brachytherapy.
PURPOSE A well-established body of literature supports the use of high-dose-rate (HDR) brachytherapy as definitive treatment for localized prostate cancer. Most of the articles describe HDR as aExpand

Daily electronic portal imaging of implanted gold seed fiducials in patients undergoing radiotherapy after radical prostatectomy.
PURPOSE The aim of this study was to measure interfraction prostate bed motion, setup error, and total positioning error in 10 consecutive patients undergoing postprostatectomy radiotherapy. Expand

Optimization of HDR brachytherapy dose distributions using linear programming with penalty costs.
Prostate cancer is increasingly treated with high-dose-rate (HDR) brachytherapy, a type of radiotherapy in which a radioactive source is guided through catheters temporarily implanted in theExpand

Stereotactic body radiotherapy as monotherapy or post-external beam radiotherapy boost for prostate cancer: technique, early toxicity, and PSA response.
PURPOSE High dose rate (HDR) brachytherapy has been established as an excellent monotherapy or after external-beam radiotherapy (EBRT) boost treatment for prostate cancer (PCa). Recently, dosimetricExpand

Inverse planning for interstitial gynecologic template brachytherapy: truly anatomy-based planning.
PURPOSE Commercially available optimization schemes generally result in an undesirable dose distribution, because of the particular shapes of tumors extending laterally from the tandem. DoseExpand

Needle insertion and radioactive seed implantation in human tissues: simulation and sensitivity analysis
TLDR
A 2D dynamic FEM model based on a reduced set of scalar parameters such as needle friction, sharpness, and velocity, where the mesh is updated to maintain element boundaries along the needle shaft and the effects of frictional forces are simulated. Expand

Sensorless planning for medical needle insertion procedures
TLDR
A sensorless planning system for needle insertion that incorporates numerical optimization with a soft tissue simulation based on a dynamic FEM formulation that models the effects of needle tip and frictional forces using a 2D mesh. Expand
