## Indications for use
The DVS (Dose Verification System) is intended for use in radiation therapy to verify treatment planning and radiation dose to tissue and organs in or near the irradiated areas of a patient. The DVS system is specifically indicated for breast and prostate cancer to measure photon beam therapy and as an adjunct to treatment planning to permit measurement of the in vio radiation dose received at the tumor periphery, tumor bed and/or surrounding normal tissues for validation of the prescribed dose.
