Abstract

A method and system of imaging of a vessel is provided. The system can include a matrix transducer array (120) for transmitting ultrasonic waves into a region of a body having a vessel and receiving echoes in response, where the echoes are associated with blood flow through the vessel; and a processor (100) operably coupled to the matrix transducer array. The processor can adjust positions of sample volumes (250) associated with the echoes. The processor can electronically steers the ultrasonic waves at one or more of the positions of the sample volumes. The processor can determine a wall of the vessel at each of the positions of the sample volumes based on a Doppler spectrum captured at each of the positions of the sample volumes. Other embodiments are disclosed.

Description

technical field [0001] The present invention relates generally to imaging systems, and more particularly to methods and systems for imaging blood vessels. Background technique [0002] Imaging blood vessels may be based on detecting blood flow through the blood vessels. For example, transcranial Doppler is a test that measures the velocity of blood flow through blood vessels in the brain to diagnose subarachnoid hemorrhage, among other problems, such as thrombosis, stenosis, vasospasm. [0003] Transcranial Doppler can be performed with "B-mode" imaging, which displays a two-dimensional image of what the ultrasound probe sees. Once the operator is able to locate the desired vessel, blood flow velocity can be measured using a pulsed Doppler probe, which plots the velocity versus time. Together these form a bidirectional test. The second recording method may use only the second probe function, and may also rely on the operator's training and experience to find the correct v...
