How does Image-Guided SRT work?

Image-Guided SRT (Image-Guided Superficial Radiotherapy) kills skin cancer cells using low levels of X-ray energy. This energy is like what dentists use to X-ray teeth. It is given by a radiation therapist in a dermatologist’s office.

Treatment is given in small doses over time. For most people, this means 3 to 5 treatments per week for several weeks. Each treatment is painless and takes about 15 minutes.

Image-Guided SRT is the first and only skin cancer treatment that uses ultrasound images. This is different than traditional SRT, which uses radiotherapy without the benefit of ultrasound images. The ultrasound images let your dermatologist see the exact size of the cancer so he or she can target the area with the precise dose. These images also show the cancer shrinking and going away after each treatment.
