Paths are determined for high intensity focused ultrasound. A subset of possible paths is selected for the application of high intensity focused ultrasound. Obstructions (e.g., bone or metal), tissue characteristics (e.g., organ or tissue sensitivity to heat or attenuation characteristic), distance, or another factor are used to select the scan lines for high intensity focused ultrasound. The selection may be aided by ultrasound imaging data, such as data representing a volume. The response from different regions is used to identify the tissue characteristics or obstructions. The factors may also be used to determine a dose (power) and/or frequency of the high intensity focused ultrasound.
