Temperature distributions in the human brain model during ultrasound hyperthermia
One of the important applications of ultrasound hyperthermia is temperature elevation at specified locations in the human brain. The ultrasound applicator used is a circular phased array surrounding the human head. The human head model is assumed to be two concentric spheres of skin and bone containing a hemisphere of brain. The single and multiple foci patterns of the ultrasound intensity generated by the circular phased array is investigated. The heating patterns, temperature distributions, corresponding to the absorption of ultrasound in the brain region is determined by solving the bioheat equation.
