For Patients

Radiation therapy is a cornerstone of cancer treatment used to cure or control the disease, including cancers of the breast and prostate. With radiation therapy, your radiation oncologist prescribes a treatment plan to provide the maximum radiation dose delivered to the tumor while minimizing the radiation to surrounding healthy tissue. To do this, radiation therapy must be accurate and consistent. Deviations from the prescribed dose delivered to the tumor or radiation accidentally delivered to healthy tissue can have a profound impact on the treatment goals and quality of life for patients treated with radiation therapy.

DVS® is an implantable sensor that is used to measure the amount of radiation that is delivered to the tumor tissue, tumor bed (where the tumor was) and/or healthy tissue. Physicians use DVS to verify that the daily radiation dose you receive is within the prescribed dose range. This information is used together with other tools used in radiation therapy to deliver more consistent daily dose and optimized treatment plans to each patient.
