摘要： A noninvasive technique that can be used to deny blood flow to a particular region of tissue, without the inherent risks associated with invasive procedures such as surgery and minimally-invasive procedures such as embolization. Blood flow in selected portions of the vasculature can be occluded by selectively treating specific portions of the vasculature with high intensity focused ultrasound (HIFU). The occlusion denies undesired tissue the nutrients and oxygen provided by blood flow, causing necrosis in the undesired tissue. An imaging technology (such as magnetic resonance imaging, magnetic resonance angiography, ultrasound imaging, Doppler based ultrasound imaging, or computed tomographic angiography) is used to identify the undesired tissue, and the vascular structures associated with the undesired tissue. A portion of the vasculature providing blood flow to the undesired tissue is selected, and HIFU is administered to the selected portion of the vasculature to occlude blood flow through that portion of the vasculature.
