Problems solved by technology

The current method cannot directly edit the VOI on the 3D image, nor can the user intuitively understand the influence of the drawing of ROI contour lines of different slices on the entire VOI extraction, making the generated VOI effect difficult to satisfy the user

Abstract

The invention discloses a region of interest extraction method. The method comprises the following steps that: first cross-sectional image data are acquired, wherein the first cross-sectional image data comprise at least a first image layer and a second image layer; a first region of interest (ROI) in the first image layer is determined; a second ROI in the second image layer is determined; and first volume of interest (VOI) is determined on the basis of the first ROI, the second ROI, and the feature information of the first cross-sectional image data. With the region of interest extraction method provided by the present invention adopted, a curved surface can be directly edited.

Description

【Technical field】 [0001] The present application relates to a medical image processing method, in particular, to a method for extracting a region of interest. 【Background technique】 [0002] With the development of science and technology, medical images are widely used in clinical medical detection and diagnosis. High-quality medical images are conducive to accurately locating lesions and improving the accuracy of diagnosis. For the tissue in the image, in the process of detection and diagnosis (for example, liver segment segmentation, tumor detection, surgical analysis, etc.), it is often necessary to mark the tissue in the image, extract the gray information of the volume of interest (VOI), and Display and observe on the 3D image. At present, the commonly used method is to draw the contour line of the region of interest (ROI) on the two-dimensional image, and then expand and display the three-dimensional VOI according to the contour line. The current method cannot direc...
