1. A skin cooling treatment system comprising:
a mechanical arm having a proximal end and a distal end;
a cryospray applicator coupled to the distal end of the mechanical arm, the cryospray applicator comprising an array of orifices, the cryospray applicator moveable by the mechanical arm to deliver a spray of cryogen to a portion of an area of skin tissue for treatment; and
a processor configured to:
receive imagery of a portion of skin of a patient for receiving a skin cooling treatment;
automatically identify boundaries from the received imagery to designate portions of the skin of the patient for receiving the skin cooling treatment;
select at least one potential treatment footprint;
generate a treatment path for the portion of skin of the patient designated for receiving the skin cooling treatment based on the identified boundaries and on the at least one potential treatment footprint;
deliver the skin cooling treatment to the skin according to the treatment path and the at least one potential treatment footprint; and
determine an instantaneous treatment footprint while delivering the skin cooling treatment to the skin according to the treatment path.
