DoseRT is Now 510K Approved.
Radiation therapy is critical in cancer treatment, but even the slightest errors can have serious consequences. DoseRT is a breakthrough technology that combines Cherenkov imaging with AlignRT and Horizon cameras, providing real-time visualization of dose delivery and patient positioning to prevent errors and improve clinical outcomes.
Published data suggests that approximately:
DoseRT provides real-time in-vivo images of dose delivery. The therapist is able to toggle between DoseRT imaging and AlignRT postural video screens during treatment. Cherenkov imaging has been clinically tested on breast, head & neck, lung, and SRS.
Cherenkov radiation is emitted when charged particles pass through the patient at the speed greater than the velocity of light in that medium. (Conceptually similar to the sonic boom.)
During radiation therapy, Cherenkov light is emitted from the patient’s skin where the radiation beam enters or exits the body.
Cherenkov imaging uses highly sensitive cameras, synchronized with both the linac and SGRT, to visualize this light from the patient’s skin.
Clinical evidence suggests that 2.6% of breast cancer patients had secondary contralateral cancer attributable to radiation.²
Cherenkov imaging captures a bolus misplacement that may have gone unnoticed without DoseRT.
Cherenkov imaging shows an otherwise undetectable change in the patient positioning resulting in a dose to the arm.
