A holding structure holds a biopsy needle and a HIFU transducer to allow smooth and accurate delivery of the HIFU beam at the interface of the liver, where bleeding will occur. This manipulator structure performs the biopsy and HIFU through the percutaneous approach. In addition, the procedure is imaged by an imaging ultrasound probe. The imaging ultrasound probe can track the needle entry site even when needle has been removed. The HIFU transducer fires a short pulse of HIFU in the needle tract to cause coagulation and stop bleeding. |
