Embodiment Construction

[0018] Embodiments of the present invention include the following steps:

[0019] 1) Before MPR reconstruction, pre-allocate a memory area (address space) dedicated to MPR reconstruction through memory mapping, and the size of the address space of the memory mapping file can be adjusted intelligently. The size of the memory-mapped file is usually the total size of the images in the MPR reconstruction sequence.

[0020] 2) Allocate a buffer area, and use multi-threading to buffer the original sequence image to the allocated buffer area to improve the speed of MPR volume data reconstruction. The original sequence images reconstructed by MPR are usually saved on the remote server, while the volume data reconstructed by MPR needs to be parsed and processed in the entire sequence images and stored in memory. Therefore, in order to improve the processing speed of the sequence image, the original sequence image is cached from the remote network end to the local buffer in advance by ...

Abstract

The invention discloses an optimized method for multi-plane reconstruction of medical images. The method is characterized in that: before multi-plane reconstruction, a memory area (address space) is pre-allocated for multi-plane reconstruction by way of memory mapping; The images that need to be reconstructed are cached in the file. During the reconstruction process, during the reading process of the sequence images, the multi-thread pre-caching method is used. Before the volume data is constructed, the read-ahead thread is used to reconstruct the image from the network. The image sequence is pre-read to the cache, and this process is carried out synchronously with the reconstruction main thread; during the reconstruction calculation, the entire sequence image is segmented, and the multi-thread segmentation calculation is used. By adopting the technical solution of the present invention, the execution time of the medical image processing program can be reduced, the operating efficiency of the program can be improved, and the purpose of optimizing medical image reading can be achieved.

Description

technical field [0001] The invention relates to medical image communication and transmission technology, in particular to an optimized medical image multi-plane reconstruction method. Background technique [0002] Multi-planar reconstruction (MPR, multi-plannerreformation) is to superimpose all the axial images within the scanning range, add up the reconstructed line images marked by certain reticle lines, and perform coronal reconstruction of the tissues designated by the lines marked by certain reticle lines. , Sagittal, any angle oblique image reconstruction. A new tomographic image can be generated arbitrarily without repeated scanning. [0003] In the existing multi-planar reconstruction technology in the medical field, the data of the entire sequence of images is used as the original data, and the entire sequence of images usually needs to be loaded into the memory. When the sequence of images to be reconstructed is very large, it is also necessary to apply for a lar...
