Abstract

The invention discloses a positioning method and apparatus for the liver scope in a medical image. The positioning method comprises the steps: acquiring a three dimensional medical image which is formed by a group of two dimensional medical images and covers the liver; determining the position the rib, in the three dimensional medical image, in the two dimensional medical images; based on the position of the rib, determining the position of the bottom of the liver in the two dimensional medical images; determining the position of the top of the liver in the two dimensional medical images; and according to the positions of the bottom and the top of the liver in the two dimensional medical images, determining the scope of the liver in the three dimensional medical image. The positioning method and apparatus for the liver scope in a medical image only need the current image data and have no demand for the prior information of a training sample or a probability graph.

Description

technical field [0001] The invention relates to the field of medical image processing, in particular to a method and device for locating a liver range in a medical image. Background technique [0002] In large-scale medical imaging equipment, it usually involves image processing for different organs, computer-aided diagnosis or quantitative analysis of index parameters. For this kind of medical image data, the image volume data (volumedata) covering the area of ​​the organ to be analyzed is generally collected and reconstructed when the medical imaging equipment is scanned, and then the application module corresponding to the organ to be analyzed performs specific diagnostic analysis. The image volume data here is a 3D medical image, usually composed of a set of 2D medical graphics. For example, image volume data obtained by image acquisition of a human torso can be used for diagnostic analysis of multiple organs (such as lungs, heart, liver, or intestinal tract). In each ...
