What is Image Guided Superficial Radiotherapy?

IG-SRT Machine

If you’ve been researching non-melanoma skin cancer treatments for Basal cell or Squamous cell carcinoma, you may have read about Superficial Radiotherapy (SRT). SRT is a highly effective non-surgical treatment alternative to more invasive methods like simple excision and Mohs surgery. It offers an advanced way to destroy cancer cells with extreme precision, without compromising the surrounding healthy tissues. 

Many patients know about SRT as a treatment option, but fewer are aware that an even more accurate treatment method exists. Called Image Guided Superficial Radiotherapy (IG-SRT), it introduces Ultrasound Imaging to the standard method of SRT. In the guide below, we’ll take a closer look at how SRT works and the benefit of seeking out IG-SRT at medical practices near you

How Does Superficial Radiotherapy (SRT) Work?

SRT treats non-melanoma skin cancer with low-level radiation. An advanced device called the SRT-100™ delivers a precise, calibrated dose of energy directly below the skin’s surface, targeting and destroying the cancer cells. SRT preserves the surrounding healthy tissues in the process – unlike surgical treatments, which remove a margin of the healthy skin surrounding the lesion. 

The SRT treatment process is painless and requires no anesthetics or cutting of the skin. Patients do not need to worry about scarring, which makes SRT a great option for cases of skin cancer on visible areas like the nose, face, neck, and chest. 

How Does Image Guided Superficial Radiotherapy (IG-SRT)  Differ From SRT?

IG-SRT introduces Ultrasound Imaging to SRT technology to allow the Radiation Therapist to view the area they are treating below the skin’s surface, as they are treating it. The device used for IG-SRT is called the SRT-100 Vision™. It is developed by Sensus Healthcare, the same company that manufactures the SRT-100™ device. 

The benefit of choosing a practice that offers IG-SRT is that your Radiation Therapist can target the cancer cells just below your skin’s surface with even greater accuracy. They can view the full depth of a lesion and use the information to determine the exact dose of low-level radiation that is needed to treat it. Patients can get a more individualized treatment plan, tailored to their case.
