Abstract
Dermatological systems and methods for providing a therapeutic laser treatment wherein the duration of a therapeutic laser pulse is based on one or more determinations of a surface temperature of the skin during the delivery of the pulse. Initiation of the therapeutic laser pulse may be based on sensed skin temperature during a cooling of the skin prior to initiation of the pulse.
Claims13
A method of treating the skin of a patient with a therapeutic laser pulse, the method comprising:
- a) initiating the application of a therapeutic laser pulse to a target skin area at a first timepoint;
- b) determining a surface temperature of the target skin area a plurality of times, at a temperature sampling interval of 100 msec or less, during the application of the therapeutic laser pulse to the target skin area based on infrared energy radiated from the target skin area;
- and
- c) terminating the application of the therapeutic laser pulse to the target skin area at a second timepoint based at least in part on the plurality of surface temperature determinations, wherein each of the plurality of surface temperature determinations occurs during a single therapeutic laser pulse having a pulse duration comprising the period from the first timepoint to the second timepoint.
