Sonication thermometry protocol. a: At timepoint ta0 a baseline reference image prior to turning on ultrasound is acquired. Images are acquired every 3.2 seconds throughout the sonication period. The final image tafinal is acquired after the ultrasound has been turned off for two 3.2-second intervals. Images are not acquired through the remainder of the cooling period. b: The following sonication where the assumption is made that baseline temperature has returned to 37°C. However, in cases of local heat accumulation the curve may actually be shifted due to insufficient tissue cooling between sonications.
