Title:
A system and a method of following and guiding a high-density focused ultrasonic wave beam
Document Type and Number:
Japanese Patent JP6006473
Kind Code:
B2
Abstract:
The present disclosure provides systems and methods for tracking and guiding high intensity focused ultrasound beams (HIFU). More particularly, the disclosed systems and methods involve use of acoustic radiation force impulse (ARFI) imaging to detect the focal position of an HIFU capable transducer relative to a target area. The focal position may then be 5 compared to a desired treatment location and the orientation and focus of the transducer may be adjusted accordingly so as to reconfigure and/or refocus the HIFU beam relative to the desired treatment location. The desired treatment location may be dynamically determined using bleed detection and localization (BD&L) techniques. Thus, the desired treatment location may be determined using 3D Doppler ultrasound based techniques, wherein changes in quantitative 10 parameters extracted from the Doppler spectra, e.g., Resistance Index (RI), are used to detect and localize a bleeding site for treatment.
