Abstract

The invention discloses a three-dimensional blood flow velocity imaging method and device based on lamellar light. The three-dimensional blood flow velocity imaging method comprises the following steps of performing layered irradiation on a sample through the lamellar light; collecting each layer of signals scattered when the layered light irradiates the sample, and for each layer, collecting a frame of image at a time interval of 1/f to obtain m frames of original blood flow images until the images at all the layers are collected; constructing the m frames of original blood flow images to obtain dynamic blood flow images at the th layer until dynamic blood flow images of all layers are obtained; performing three-dimensional reconstruction on the dynamic blood flow images of all layers toobtain three-dimensional blood vessel distribution; and calculating the three-dimensional blood vessel speed according to the three-dimensional blood vessel distribution. The device comprises a lamellar light irradiation system, a collecting system and a processing system. Compared with the prior art, the three-dimensional blood vessel speed can be well obtained. The method and device are mainly applied to the technical field of image processing.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a three-dimensional blood flow velocity imaging method and device based on sheet light. Background technique [0002] Full-field optical blood flow imaging technology has the advantages of non-contact, non-destructive, large field of view and high resolution. It is often used to study physiological processes such as in vivo blood vessel growth, blood flow velocity changes, and blood perfusion. It is also used in pathological research and disease diagnosis. has broad application prospects. [0003] Chinese Patent Document No. CN105574861A discloses a marker-free blood flow imaging method and system, by continuously collecting several frames of images under the same exposure time and acquisition time, and then performing Fourier transform on the time series of each pixel point and Perform high-pass filtering to obtain high-frequency signals, and then perform Doppler frequ...
