Problems solved by technology

Although the multi-window technology solves the problem of enhancing the display of different organs at the same time, due to the simultaneous display of multiple organs, it causes a lot of interference to the observer's sight, which has a great impact on the doctor's correct diagnosis

Embodiment Construction

[0030] The present invention will be further described in detail below with reference to the drawings and flowcharts.

[0031] The method for automatically generating color multi-window CT images of the present invention is completed in the following specific steps.

[0032] 1. Regional segmentation, the process is shown in Figure 24.

[0033] Here, the purpose of region segmentation is to segment the regions where the different organs or tissues contained in the CT image are located. Taking the lung CT image as an example, the region segmentation method will be described in detail.

[0034] Step 1: Binary processing

[0035] In CT images, each organ or tissue has its specific CT value, in other words, each different organ or tissue has its different window width and window level. Therefore, the present invention provides two methods for determining threshold values ​​for users to choose. The first method is to set a default method according to the imaging principle, and select a ...

Abstract

The invention provides an automatic generating method for color multi-window CT image of specification digest. The CT image is carried on region-dependent segmentation at first; the variable organ and organization belong to different local region. The method carries on automatic region-dependent segmentation according to the distribution range of the different CT values of the organ or organization when using CT to image, and to topology information of the organ; the secondly, the correction process is carried on to the segmented regions. The third, carries on coloring process to the region with different color, finally generate the pathology report list, prints and outputs the multi-window color CT image and the diagnosing result.

Description

Technical field [0001] The present invention relates to an automatic processing method for CT images, in particular to a method for automatically generating color multi-window CT images. The method relates to image segmentation technology, pseudo-color technology, and the establishment of the mapping relationship between multi-window technology and different tones . Background technique [0002] CT image processing technology is currently mainly based on its imaging principle, through the corresponding single gray-level window technology to enhance the concerned part in the corresponding CT image, to provide doctors with a basis for disease diagnosis. Because the tumor metastasis will cause erosion to other organs or tissues, for example, the spread and metastasis of cancer cells. So multi-window technology is very important in reflecting this problem. Although the multi-window technology solves the problem of simultaneous enhanced display of different organs, the simultaneous di...
