Embodiment Construction

[0023] Example 1, with figure 2 The result shown is an example;

[0024] Start: the program reads in the corresponding image data file conforming to the DICOM standard, the user activates the skin extraction button, and the program software automatically enters the skin extraction process;

[0025] Establish a mathematical model of skin tissue: the program automatically judges the image data type, and recognizes the CT scanning device as CT according to the DICOM standard image information, and then gives the corresponding skin mathematical model according to the CT scanning device:

[0026] EV [nMin, nMax]

[0027] Among them, the value of nMin is -200, and the value of nMax is 3072

[0028] Determine tissue growth point: The program automatically finds the seed point, which is the starting point of tissue growth, based on the mathematical model of the skin. During the scanning process, the surrounding area of ​​the skin is filled with air ...

Abstract

The automatic extraction process of skin image in medical image segmentation includes the following steps: exciting the button to start the programmed automatic skin extraction process; automatic image type judgment, distinguishing the scanning equipment type based on the DICOM standard image information to give corresponding math model; determining the tissue growing point based on the math model of skin; determining the area containing skin tissue by means of tissue growing segmentation algorithm and starting from the tissue growing point; establishing stereo region and determining the boundary area; performing tissue growth by means of the obtained tissue growing start point to obtain tissue area containing skin; and eliminating bed board to obtain skin tissue. The present invention has the obvious effect of precise automatic skin extracting process.

Description

technical field [0001] The invention relates to an automatic skin extraction method in medical image segmentation, in particular to an automatic skin extraction method in medical images. Background technique [0002] At present, in all kinds of medical image processing, most of them still use semi-automatic extraction algorithms with manual participation. The semi-automatic extraction algorithm using manual participation requires more work from the user. Generally, the software provides various image editing tools, and then the user manually edits the current segmented area to delete the non-skin tissue area in the area. These tasks are very tedious, but the results are often not very satisfactory. Contents of the invention [0003] In view of the defects still existing in the above-mentioned known technologies, the purpose of the present invention is to provide a program software, which realizes the automatic completion of the whole skin extraction process, and makes the...
