Cherenkov radiation is emitted when charged particles pass through the patient at a speed greater than the velocity of light (conceptually similar to a 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.
By capturing Cherenkov light emitted during treatment, DoseRT provides a non-invasive, visual verification of dose delivery. This ensures accurate and precise radiation therapy, improving patient safety and confidence in treatment outcomes.
Clinical evidence suggests that 2.6% of breast cancer patients had secondary contralateral cancer attributable to radiation.¹
Cherenkov imaging captures a bolus misplacement that may have gone unnoticed without DoseRT.
Cherenkov imaging shows an otherwise undetectable change in the patient’s positioning, resulting in a dose to the arm.
