The OARtrac® System with patient specific, reusable, pre-calibrated PSD sensors are intended for use during cancer treatments to measure photon radiation therapy as an adjunct to treatment planning permitting measurement and validation of radiation dose received by the patient to the targeted area of their body, and indicated for use when adhered to the skin with a bolus, or inserted into the rectum to measure the rectal prostatic interface via a specifically designed endorectal balloon device.

The OARtrac® System with patient specific, reusable, pre-calibrated PSD sensors is intended for use in photon radiation therapy to monitor and validate radiation dose during External Beam Therapy and HDR Brachytherapy to the surface of the skin or the rectal prostatic interface. This dose verification information obtained during the treatment is then used to compare with the planned dose that the Radiation Oncologists expect to provide to their patient. The OARtrac® System itself does not stop the radiation treatment to the patient, or change the radiation delivery, but only provides dose data which a trained Radiation Oncologist can decipher and use to adjust a patient's treatment plan accordingly.

The OARtrac® System pre-calibrated skin sensors are specifically indicated for use during cancer treatments to measure photon beam therapy as an adjunct to treatment planning permitting measurement of radiation dose received on the surface of the skin. OARtrac® System pre-calibrated skin sensors are indicated for use when adhered to the skin using medical grade adhesive and with a medical grade bolus buildup placed directly on top of the sensor.

The OARtrac® System with Skin Sensors provides Radiation Oncologists with near real-time, multi-point radiation-dose information obtained from two (2) Radiatrac® Plastic Scintillating Detectors (PSD) located on the surface of the patient's skin to monitor dose photon based radiation therapy for cancer treatment. This information allows the physician to monitor the dose at the skin surface, compare the actual dose relative to the planned dose, and provides graphs and dose information for the current treatment as well as a log of the dose from five previous treatments. The actual verification of the dose radiation is accomplished by the other main components of the OARtrac® System, those being the Clinical Detector Unit (CDU) with its Charged Coupled Device (CCD) camera and the system's own proprietary dose management software.

The RadiaPak™ Brachytherapy Applicator Balloon Device is a single use, non-sterile, disposable, inflatable, non-powered positioning device, manufactured without the use of latex, intended to be used on a daily treatment basis to position and stabilize the brachytherapy radiation delivery applicator within the vagina or rectum during brachytherapy radiation therapy procedures, x-ray, or computed tomography (CT) exam. The placement of the balloon device requires a physician directed healthcare professional.

The RadiaPak™ Device is designed to position and stabilize the brachytherapy applicator and to space the applicator surface from the targeted vaginal or rectal mucosa during computed tomography and brachytherapy procedures. The proposed device is a latex free balloon and can be inflated with either air or saline, is provided non-sterile, and is intended for single use.
