Image Guided Superficial Radiation Therapy IGSRT in Northern Colorado

What is IG-SRT?

Image-Guided Superficial Radiotherapy (IG-SRT) is a non-invasive therapy conducted in a medical professional’s office. It employs low doses of X-ray energy to effectively eliminate cancer cells while facilitating the regrowth of healthy tissue in the treated area. This modern technique combines  radiation therapy with advanced imaging technology. It targets the skin and shallow tissues while minimizing damage to surrounding areas.

What to expect with Image Guided Superficial Radiation Therapy IG-SRT

During an IG-SRT session, you will be comfortably seated as a specialized gel is applied to the area affected by cancer. The doctor will then employ a small imaging wand to capture a highly detailed image of the cancerous site, which will be displayed on a screen. This image serves as a reference for measuring the tumor’s size and shape, determining the appropriate treatment dose, and delineating the precise treatment area.

Once these preparations are complete, the treatment device’s arm will be positioned over the designated area, delivering a targeted dose of X-ray energy that accurately focuses on the cancer while sparing the surrounding healthy tissue from harm. IG-SRT is administered in stages, typically involving 3 to 5 treatments per week over a span of 4 to 7 weeks. Each treatment is painless and can be completed in as little as 15 minutes.

Multiple tumors, up to a maximum of 3, can be treated simultaneously, and the treatment dose can be adjusted at each stage based on the tumor’s response.

GentleCure is a gentle, surgery-free treatment that is safe and has a 99%+ cure rate in certain basal and squamous cell skin cancers. Treatment is done right in our dermatology office over the course of a few weeks using an advanced Image-Guided Superficial Radiation Therapy machine. It is the only skin cancer treatment with ultra-sound imaging that lets you see the cancer on the screen and review the progress made throughout the course of treatment until there are no visible signs of cancer.


About treatment – At each treatment session, you will sit in a chair and ultrasound gel will beapplied to the site of the cancer. Using an imaging wand, we will look at a detailed image of your cancer on screen. You can see the image yourself from the comfort of the chair. We will use that image to measure the size and shape of the tumor, calculate the precise dose of treatment, and define the treatment area. Once the imaging is complete, the arm of the device will be placed over the treatment site and the exact dose of X-ray energy will be used to treat the cancer site without harming the healthy tissue around it. Each treatment session takes about 15 minutes from the time you walk in the door to when you leave the office. You will come back several times a week for short treatment sessions, and in 4-to-7 weeks, treatment will be complete.
