Embodiment 1

[0062] The method of constructing three-dimensional images of intracranial blood vessels by using the transcranial Doppler instrument with automatic monitoring probe of Delikai Company:

[0063] First, scan the intracranial from the left temporal window. The number of scanning lines of the probe is 31*31=961, the angle difference between each two lines is about 1.47°, and the sampling points on each scanning line are 128 points. The interval between two points is 1mm.

[0064] Then, perform complex correlation calculation on the ultrasonic echoes of each line to obtain 128 blood flow energy and direction information. In this way, the data of 123,008 intracranial points can be accumulated from one side of the temporal window, and a three-dimensional image of intracranial blood flow can be obtained after three-dimensional reconstruction.

[0065] Afterwards, the automatic probe is controlled to scan again all the wave velocity positions displaying blood flow information, and fa...

Abstract

The invention provides a transcranial Doppler intracranial blood flow three dimensional information display method and system; the method comprises the following steps: a, using a transcranial Doppler ultrasonic probe to do multi-beam supersonic wave scanning for an intracranial predetermined area, and receiving an ultrasonic echo signal; b, calculating the ultrasonic echo signal to obtain blood flow information like intracranial blood vessel depth, blood flow direction, relative blood flow volume and blood flow speed; c, scanning the predetermined area so as to obtain blood flow information in various directions, and using three dimensional modeling calculation to form a stereo model containing blood flow information; d, doing visualization processing for the data of the stereo model so as to form a three dimensional image, and customizing and adjusting the three dimensional image according to a user order, outputting the image, and displaying the image for user. Compared with MRI, CT, DSA, the method and system are low in cost, convenient, can repeatedly detect, and can greatly reduce dependence level for experiences of an operator, thus providing more complete and objective blood flow information.

Description

technical field [0001] The invention relates to the technical field of medical ultrasound, in particular to a method and system for displaying three-dimensional information of intracranial blood flow based on transcranial Doppler. Background technique [0002] Ultrasonic transcranial Doppler blood flow analyzer detects the blood flow spectrum of intracranial arteries to obtain information such as blood flow velocity and direction, and has been widely used in clinical practice. The following probe frequencies are commonly used for transcranial Doppler (TCD) intracranial detection: 1.0MHz, 1.6MHz or 2.0MHz pulse wave. [0003] Compared with color Doppler ultrasound, TCD probe has a lower frequency and stronger penetrating power, but the spectrum image is rough and the resolution is relatively poor. The existing transcranial Doppler is mainly used to detect the blood flow information of a certain segment of the intracranial artery, or can give the blood flow information in the...
