Occlusion of blood flow by high‐intensity focused ultrasound
Journal of the Acoustical Society of America
Blood flow occlusion in vivo using a single high intensity focused ultrasound exposure is investigated. A high power 1.7 MHZ, 150 mm focal length, piezoelectric ultrasound transducer was used to expose femoral vesels to free field spatial peak intensities in the range 750-4660 Wcm"2whilst being moved at constant speed. Pre-and post-FUS exposure, submillimetre resolution magnetic resonance datasets were squired using a Siemens Vision System (1 .5~, with and without contrast agent administration.doi:10.1121/1.421631 fatcat:c55oqekcezhhpgchpggouxbt7u
