Ultrasound system with wide depth and detailed view

摘要

The present invention is an ultrasonic system for imaging a stereoscopic measurement region including a region of interest, and a probe having an array of a plurality of CMUT transducers capable of steering an ultrasonic beam within a variable frequency range over the stereoscopic measurement region. A beamformer coupled to the array for controlling ultrasound beam steering and providing ultrasound image data of the stereoscopic measurement region, and changing the operating frequency of the CMUT transducer within the frequency range. A transducer frequency controller coupled to a former, wherein the frequency controller sets the operating frequency to a first frequency for the ultrasonic beam steered in the stereometry region; and Ultrasound image data Based relates to an ultrasonic system comprising an image processor generating an ultrasonic image. The system further includes a region of interest (ROI) identifying unit that enables a region of interest to be identified based on the ultrasound image data, wherein the ROI generates identification data indicating the region of interest within the stereometric region. The transducer frequency controller further changes the operating frequency to a second frequency for the ultrasonic beam steered in the region of interest based on the identification data, wherein the second frequency is , Higher than the first frequency.
