Intracranial cerebral blood flow three-dimensional image acquisition device and method

Abstract

The invention discloses an intracranial cerebral blood flow three-dimensional image acquisition device and method. The method includes the steps that a transcranial doppler probe is utilized to conduct single-beam or multi-beam ultrasound scanning on intracranial vessels of a detected object, ultrasound echo signals are received, and calculation is conducted according to the received ultrasound echo signals, so that blood flow information is obtained; meanwhile, a space tracking locator is utilized to obtain the relative position points and angle parameters of the transcranial doppler probe, and gathering space points in the detection process are calculated in combination with the relative distance between the space tracking locator and a probe wafer and depth adjustment parameters of the transcranial doppler probe; the gathering space points with blood flow information are integrated into a curve or a curved surface, and three-dimensional image data with the blood flow information are formed. By means of the intracranial cerebral blood flow three-dimensional image acquisition device and method, three-dimensional images of all acoustic window positions can be obtained, under the situation that workload of doctors is not added, comprehensive and visualized information of intracranial cerebral blood flow is obtained automatically, it is convenient to conduct diagnosis, diagnosis leakage and error diagnosis are prevented, information is more visualized and complete, and clinical big data can be accumulated and obtained.
