Gammapod

Abstract

A dedicated stereotactic gamma irradiation device, GammaPod™ from Xcision Medical Systems, has been developed to treat early stage breast cancer. GammaPod™ offers the opportunity to deliver curative doses of radiation using stereotactic body radiotherapy (SBRT) more precisely than current radiotherapy standards, thereby minimizing the amount of breast tissue ablated and improving cosmesis. In this chapter, we review the current status of radiotherapy for breast cancer patients diagnosed with early stage disease and rationale for the development of a dedicated breast stereotactic system. Furthermore, a detailed description of the GammaPod technology, design specifications and its dosimetric characteristics are presented using comparative treatment planning studies in addition to dosimetric measurements from pre clinical prototype testing.​
