Peer-based credentialing for brachytherapy: Application in permanent seed implant

Seed implant brachytherapy for prostate cancer.

Incorporating seed orientation in brachytherapy implant reconstruction

Intra-operative quality assurance and dosimetry optimization in prostate brachytherapy critically depends on the ability of discerning the locations of implanted seeds. Various methods exist for seed matching and reconstruction from multiple segmented C-arm images. Unfortunately, using three or more images makes the problem NP-hard, i.e. no polynomial-time algorithm can provably compute the com...

Inverse planning optimization for hybrid prostate permanent‐seed implant brachytherapy plans using two source strengths

The purpose is to demonstrate the ability to generate clinically acceptable prostate permanent seed implant plans using two seed types which are identical except for their activity. The IPSA inverse planning algorithms were modified to include multiple dose matrices for the calculation of dose from different sources, and a selection algorithm was implemented to allow for the swapping of source ...

Rectal injury during permanent seed implantation for prostate brachytherapy.

Serious complications have not been previously reported during seed implantation for prostate brachytherapy. We present an unreported case of rectal injury caused by an ultrasound probe. A 67-year-old male presented with a serum prostate-specific antigen level of 5.50 ng/ml, a Gleason score of 7 (3 + 4) and clinical T2a adenocarcinoma of the prostate. A transperineal permanent prostate brachyth...

Ultrasound Image-guided Robotic Brachytherapy Systems for Prostate Seed Implant

In image-guided brachytherapy (IGBT), accurate percutaneous intervention of needle and precise placement radiation sources are challenge tasks. In traditional prostate brachytherapy, needles are introduced through fixed, parallel holes of a template where the maneuverability of the needle is extremely limited. The accuracy and consistency of needle placement and seed delivery is subject to vari...
