Three-dimensional transrectal ultrasound guided high-dose-rate prostate brachytherapy: A comparison of needle segmentation accuracy with two-dimensional image guidance.
PURPOSE Conventional transrectal ultrasound guided high-dose-rate prostate brachytherapy (HDR-BT) uses an axially acquired image set for organ segmentation and 2D sagittal images for needle segmentation. Sagittally reconstructed 3D (SR3D) transrectal ultrasound enables both organ and needle segmentation and has the potential to reduce organ-needle alignment uncertainty. This study compares the ...
متن کاملHigh-dose-rate Brachytherapy for Prostate Cancer
Introduction/Background Over the last 2 decades, significant technical advancements have improved the delivery of prostate brachytherapy. The transrectal ultrasound-guided implant technique is the backbone of modern prostate brachytherapy. Whether it is permanent or temporary, ie, low-dose-rate (LDR) or high-dose-rate (HDR), respectively, both use similar image-guided techniques for inserting s...
متن کاملAAPM Task Group 128: quality assurance tests for prostate brachytherapy ultrasound systems.
While ultrasound guided prostate brachytherapy has gained wide acceptance as a primary treatment tool for prostate cancer, quality assurance of the ultrasound guidance system has received very little attention. Task Group 128 of the American Association of Physicists in Medicine was created to address quality assurance requirements specific to transrectal ultrasound used for guidance of prostat...
متن کاملRobotically assisted prostate brachytherapy with transrectal ultrasound guidance--Phantom experiments.
PURPOSE To report the preliminary experimental results obtained with a robot-assisted transrectal ultrasound (TRUS)-guided prostate brachytherapy system. METHODS AND MATERIALS The system consists of a TRUS unit, a spatially coregistered needle insertion robot, and an FDA-approved treatment planning and image-registered implant system. The robot receives each entry/target coordinate pair of th...
متن کاملSeed Localization in MRI-guided Prostate Brachytherapy using Inversion-Recovery With ON-Resonant Water Suppression (IRON)
Introduction: Prostate brachytherapy is a common treatment for low-risk prostate cancer involving the insertion of needles in precise locations of the prostate to implant rice-like radioactive sources known as seeds. Seed localization in relation to the prostate is one of the major current limitations of intraoperative treatment planning for prostate brachytherapy [1]. This issue limits the eff...
