John Theurer Cancer Center at Hackensack (N.J.) University Medical Center will use an implantable, wireless radiation sensor to immediately measure after treatment the amount of radiation delivered to tumors and surrounding tissue for treatment of prostate cancer.

The hospital is using the DVS (dose verification system) of Sicel Technologies Inc., Morrisville, N.C. DVS includes a sensor--2.1 millimeters in diameter and 20 millimeters long--implanted during a minimally invasive procedure.

The sensor wirelessly transmits data, including the amount of radiation absorbed, to a hand-held monitor, enabling a clinician immediately after treatment to verify that the patient received the prescribed dose. The system also can help determine whether radiation was accidentally administered to healthy tissue.
