Focused Ultrasound Therapy
Focused ultrasound is a therapeutic technology that could transform the quality of life and decrease the cost of care for patients with the pre-malignant disease of actinic keratosis. This novel technology focuses beams of ultrasound energy precisely and accurately on targets in the body without damaging surrounding normal tissue.
How it Works
Where the beams converge, focused ultrasound produces thermal ablation (burning) of the target tissue.
The primary options for treatment of actinic keratosis include cryotherapy (freezing the effected tissue) or more invasive surgery. For certain patients, focused ultrasound could provide a noninvasive alternative to surgery with less risk of complications – such as like surgical wound healing or infection – at a lower cost. Focused ultrasound can reach the desired target without damaging surrounding tissue, and it can be repeated, if necessary.
At the present time, there are no clinical trials recruiting patients for focused ultrasound treatment of actinic keratosis.
Regulatory Approval and Reimbursement
Focused ultrasound treatment for actinic keratosis is not yet approved by regulatory bodies or covered by medical insurance companies.
