114: Patient Positioning and Mark-Up Optimization for Permanent Breast Seed Implant (PBSI)

Adjuvant stereotactic permanent seed breast implant: a boost series in view of partial breast irradiation.

PURPOSE The aim of this study was to use permanent seed implants in the breast and describe our experience with 15 cases, using iodine seed implants as a tumor bed boost. METHODS AND MATERIALS Breasts were fixed with a thermoplastic sheet, a template bridge applied, the thorax scanned and the images rotated to be perpendicular to the implant axis. Skin, heart, and lung were delineated. A prep...

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 ...

Optimized planning for intraoperative planar permanent‐seed implant

We describe a fast, PC-based optimization planning system for a planar permanent-seed implant. Sites where this system is applicable include brain, lung, and head and neck. The system described here allows placing ribbons of different strengths and of different lengths along and across the implant plane. The program takes full advantage of the availability of different source strengths in inven...

A system for breast implant selection based on patient tissue characteristics and implant-soft tissue dynamics.

Primary breast augmentation patients have widely varying characteristics of their breast envelope, parenchyma, and adjacent tissues. When preoperative breast implant selection does not specifically address critical soft-tissue parameters individual to each patient, risks of complications increase. Complications that occur from failure to reconcile a patient's wishes for breast size with her ind...
