Hyperthermia treatment planning (HTP) is becoming available for individual patients. The components of a HTP system have been described. As an example for the application of HTP in therapeutic ultrasound the temperature distribution in a bovine tongue, heated with a scanning ultrasound focus, is calculated using the Discrete VAsculature (DIVA) thermal model. This model is capable to describe the individual thermal behavior of the discrete blood vessels. Simulations show the overall temperature heterogeneity and the severe thermal underdosage of the tissue around large passing vessels. This implies that in the application of therapeutic ultrasound for malignant tumors great care must be taken.
