Intravascular forward-looking ultrasound transducers for microbubble-mediated sonothrombolysis

SCIENTIFIC REPORTS, 7.

By: J. Kim n, B. Lindsey  n, W. Chang n, X. Dai*, J. Stavas *, P. Dayton n, X. Jiang*

MeSH headings : Humans; Microbubbles; Thrombolytic Therapy / instrumentation; Thrombolytic Therapy / methods; Transducers; Ultrasonic Waves
TL;DR: It is hypothesized that a sub-megahertz, forward-looking ultrasound transducer with an integrated microbubble injection tube is more advantageous for efficient thrombolysis by enhancing cavitation-induced microstreaming than the conventional high-frequency, side-looking, catheter-mounted transducers.
