Hepatic Tumor Ablation

One method for removing cancerous tumors from healthy tissue is to heat the malignant tissue to a critical temperature that kills the cancer cells. This example accomplishes the localized heating by inserting a four-armed electric probe through which an electric current runs. Equations for the electric field for this case appear in the Electric Currents interface, and this example couples them to the bioheat equation, which models the temperature field in the tissue. The heat source resulting from the electric field is also known as resistive heating or Joule heating.

This model uses the Bioheat Transfer interface and the Electric Currents interface to implement a transient analysis.

MEDICAL ENGINEERING: Heating cancerous tumor tissue to a critical temperature can kill these cancerous cells. A four-armed electric probe through which an electric current runs is modeled where the bioheat equation is coupled to the electric current.
