Three-dimensional photoacoustic tomography method, device and equipment and readable storage medium

The invention discloses a three-dimensional photoacoustic tomography method, device and equipment and a readable storage medium, a reference respiration frame number is determined based on a respiration graph of each piece of original photoacoustic data, so that each three-dimensional volume data block obtained through three-dimensional reconstruction according to each piece of original photoacoustic data is obtained; and extracting each piece of target three-dimensional body data corresponding to the three-dimensional body data block of the reference breathing frame number as a target three-dimensional body data block, and then splicing each target three-dimensional body data block to obtain a three-dimensional photoacoustic image. Visibly, according to the scheme that the target three-dimensional body data of the reference breathing frame number is selected from the three-dimensional body data blocks to construct the target three-dimensional body data blocks, and the three-dimensional photoacoustic image is
