Figure 1From: Changes in clot lysis levels of reteplase and streptokinase following continuous wave ultrasound exposure, at ultrasound intensities following attenuation from the skull bone The field distribution for the transducer used in the present study. Needle hydrophone exploration of field distribution for the transducer. Scanning was performed over an area of 50 × 30 mm2 in the y- and z-direction starting close to the transducer surface. No exact values of intensity were measured. Clots were placed 30 mm from the transducer surface.Back to article page
