The world’s first stereotactic radiotherapy system optimized for treating breast cancer.
With GammaPod™, radiation oncologists can be at the forefront of a new era in cancer care by providing Stereotactic Partial Breast Irradiation (S-PBI), an advanced type of SBRT, for breast cancer. The delivery of higher doses in one or several large fractions differentiates stereotactic radiotherapy from conventional techniques.
Born out of the vision to extend the dosimetric benefits of stereotactic radiotherapy to patients undergoing breast conserving treatment, GammaPod™ is a new precision tool with the potential to change the way early stage breast cancer is managed.
The ability to safely and confidently deliver a focal dose of radiation to a target within the breast is giving clinicians the opportunity to take breast radiotherapy to new levels.
With GammaPod™, radiation oncologists have a new tool for delivering ultra-accelerated courses of adjuvant stereotactic partial breast irradiation, reducing tumor bed boosts to a single fraction for patients receiving whole breast irradiation and neoadjuvant treatments at ablative dose levels.
GammaPod™combines a continuously rotating, 25-source irradiation unit with 15 mm and 25 mm collimators and dynamic table motion during treatment to paint the radiation dose to the target.
Stereotactic radiotherapy requires a high degree of precision to ensure accurate dose delivery. The GammaPod uses a first of its kind vacuum-assisted, dual-cup system that adheres noninvasively to the breast.
The GammaPod™ breast cup system provides breast tissue immobilization, serves as a stereotactic frame and enables reproducible setup between imaging and treatment.
Patients are custom fit with the appropriately sized inner cup. Inner cup is joined via a silicone flange to a rigid outer cup containing an embedded stereotactic fiducial wire.
Adhesive on the flange helps the device adhere to the patient. Attached suction pump evacuates the air from between the cups to provide a stable immobilization.
Clinical trials have found that prone positioning for breast cancer radiotherapy offers multiple benefits. The affected breast naturally falls away from chest wall and treatments can be designed to limit dose to the heart and lungs.
The GammaPod uses prone patient loaders in the imaging and treatment rooms to quickly and comfortably set up patients in the prone position. Providing reproducible setup at the time of imaging and treatment obviates the need for in-room image guidance.
The GammaPod treatment planning system (TPS) uses sophisticated Monte Carlo dose calculations, the gold standard in radiotherapy, to create a dynamic travel path along which the couch will during the delivery of the prescribed dose. To accommodate the scan-plan-treat clinical workflow, the TPS provides clinicians with tools for quickly creating a new treatment plan each day based on changes to the target and anatomy.
Single-click localization of the stereotactic fiducial wire.
Intuitive contouring tools for defining the GTV with interpolation between image slices.
Easy creation of uniform margin expansion to define PTV.
Rapid optimization based on plan goals.
Following approval, plans are transported to the treatment control system for verification and delivery.
