Abstract
A method for performing radiation treatment of skin in connection with dynamic cooling of tissue, while minimizing or preventing occurrence of light flash during the treatment.
Claims27
A method for performing radiation treatment of skin having an epidermal tissue region adjacent a dermal tissue region, the method comprising:
- a) cooling the epidermal tissue region by applying a cryogenic fluid to the epidermal tissue region;
- b) directing a gas flow in general direction of the epidermal tissue region subsequent to step a) to remove at least a portion of the cryogenic fluid applied to the epidermal tissue region;
- and
- c) irradiating the skin with a radiation beam to treat the dermal tissue region subsequent to removing at least a portion of the cryogenic fluid to prevent a light flash during the irradiation step.

A method of performing radiation treatment of skin having an epidermal tissue region adjacent a dermal tissue region, the method comprising:
- a) applying a first pulse of cryogenic fluid to the epidermal tissue region for a first time period;
- b) waiting a delay period of a predetermined time interval before applying a second pulse of cryogenic liquid to the epidermal tissue region for a second time period, the delay period being sufficient to allow the first pulse of cryogenic fluid to cool the epidermal tissue region to reach a desired temperature;
- and
- c) irradiating the skin to treat the dermal tissue region during or immediately after application of the second pulse of cryogenic liquid, thereby preventing a light flash during the irradiation step.
