ABSTRACT
A new methodology to control the freezing front propagation
during cryosurgical procedures is studied through the use of
numerical techniques. Laser irradiation of a target tissue is
explored as a new methodology for localizing heat generation
and, thus, confining more accurately the desired cryoinjury
region and to protect a thicker superficial layer of tissue. In
addition to the irradiation of laser energy, the use of dyes is
proposed as a means of localizing heat absorption and
