Why does IG-SRT use ultrasound imaging during treatment?

The ultrasound imaging is what makes IG-SRT especially precise. By using ultrasound before each treatment, the dermatologist can see exactly where the cancer is under the skin and how deep it goes. This information is crucial – it allows the doctor to calibrate the treatment area and radiation dose to the tumor’s exact size and shape, ensuring the full cancer is treated while sparing as much healthy tissue as possible. Ultrasound guidance also lets the medical team watch the tumor shrink over the course of treatment. In practical terms, the imaging provides a live map of the cancer: they find the precise boundaries, treat that area, and at subsequent sessions can confirm the tumor is getting smaller. This gives both patient and doctor confidence that the treatment is hitting the mark. No other skin cancer treatment has this capability of seeing the tumor during therapy – it’s a unique benefit of IG-SRT.
