4A-3 Intracranial Catheter for Integrated 3D Ultrasound Imaging & Hyperthermia: Feasibility Study

In this study, we investigate the feasibility of developing an intracranial catheter transducer capable of real time 3D (RT3D) imaging and ultrasound hyperthermia, for application in the visualization and treatment of tumors in the brain. Feasibility is demonstrated by acquiring RT3D images in a canine model using a 10 Fr, matrix array catheter transducer, and by achieving a temperature rise over 4degC in excised pork muscle using a linear array transducer with our diagnostic scanner. An integrated matrix and linear array catheter transducer prototype was constructed and used to acquire images of test phantoms.
