WebMar 2, 2016 · Ultrasound travels through tissue as a beam, which, for most clinical applications, is focused to around 1 mm or less in diameter at the focal zone. It propagates as a sequence of compression and rarefaction waves which are transmitted by the elastic forces between adjacent tissue particles. WebApr 11, 2024 · For X–Y and X–Z planes scanning with 1-mm steps, the hydrophone was placed at the focal zone of ultrasound transducer. The acoustic distribution on X–Y and X–Z planes were showed in the Fig. 1(B). The acoustic distribution on X–Y indicated that the full-width at half-maximum focal zone was 4 × 4 mm 2. WebApr 10, 2024 · The ultrasound foci created using FZPs are sufficiently intense for most application scenarios that are currently in practical use. We also determine favorable side effects of our method suppressing grating lobes, which is inevitable with the conventional phase-controlling method. indiana incarcerated lookup
