PHOTOTREATMENT DEVICE FOR USE WITH COOLANTS AND TOPICAL SUBSTANCES
Methods and systems are disclosed for phototreatment in which replaceable containers comprising one or more adjuvant (consumable or re-usable) substances are employed. The adjuvant substance can be, for example, a topical substance or a coolant. Systems are disclosed for using a topical substance to detect contact of a phototreatment device with a tissue, detect speed of a phototreatment device over the tissue, detect regions of tissue that have been treated by a phototreatment device and/or to provide other benefits to the tissue such as improved skin tone and texture, tanning, etc. Safety systems are also disclosed that ensure that a proper consumable substance and/or container is connected to a phototreatment device and/or directed to a proper target. Additionally, cooling systems and methods that utilize phase change materials for extracting heat from a light generating device are disclosed.

22 . A system for measuring a speed of motion of a phototreatment device over a tissue region, the phototreatment device having an electromagnetic source to effect a phototreatment and the tissue region having a substance applied thereto, comprising:
a radiation source positioned on the phototreatment device to irradiate the tissue region and the applied substance;
a detector associated with the phototreatment device configured and arranged to monitor the substance; and
a processor for calculating a speed of motion of the phototreatment device based on signals from the detector.
