Focused Ultrasound describes the focusing of high frequency sound waves (in the 0.2 - 10 MHz range) for the purpose of heating and ablating tissue. Also known as High Intensity Focused Ultrasound or HIFU (due to the immense intensity at the focus), focused ultrasound treatments can be guided by ultrasound or MRI. Ultrasound image guidance is capable of providing feedback on changes in tissue density and elasticity.
