Abstract

The invention provides a method for acquiring a three-view drawing of medical image, which belongs to the technical field of image processing. The method comprises: firstly, acquiring a CT medical image and performing the three-dimensional reconstruction of the medical image to obtain a three-dimensional image; reading the three-dimensional image and obtaining a three-dimensional reconstructed image by reducing the triangular plates in the three-dimensional image by using triangular plate simplification technology to reduce the image drawing time and the occupation of a memory; computing a three-view drawing normal vector and a three-view drawing position coordinate of a point according to the three-dimensional coordinate of the point in the three-dimensional reconstructed image and acquiring a cross section view, a coronal plane view and a sagittal plane view which pass through the point by conversion matrix processing, namely, acquiring the grey values of all points in the cross section view, the coronal plane view and the sagittal plane view by using a trilinear interpolation method to acquire the cross section view, the coronal plane view and the sagittal plane view. In the method, the triangles in the three-dimensional image are reduced to reduce the image drawing time and the occupation of the memory and improve interaction.

Description

technical field

[0001] The invention relates to a method in the technical field of image processing, in particular to a method for acquiring three views of a medical image. Background technique

[0002] In the current imaging medical diagnosis, doctors mainly find lesions by observing a group of two-dimensional slice images of CT (Computed X-ray Tomography) and MRI (Magnetic Resonance Imaging). film experience. Using medical visualization technology to reconstruct three-dimensional human organs from a series of continuous two-dimensional slices can truly reproduce the original appearance of objects and assist medical staff in quantitative and qualitative analysis of diseased bodies or regions of interest, which can greatly improve medical diagnosis. accuracy.

[0003] Using computer image processing technology to obtain virtual slices in other directions (such as cross-section, coronal view and sagittal view) from the tomographic image sequence can help doctors observe and...
