The invention provides a hepatic artery segmentation method based on a CT image, and the method comprises the steps: loading the CT image data of hepatic artery and the corresponding liver mask data, and positioning a seed point of the hepatic artery; segmenting the CT image data, and respectively obtaining first two-valued volume data comprising vertebra and ribs connected therewith, and second two-valued volume data comprising vertebra, ribs connected therewith and the hepatic artery; removing a part, the same as the first two-valued volume data, in the second two-valued volume data, and obtaining third two-valued volume data; carrying out three-dimensional regional growing on the third two-valued volume data through the seed point of the hepatic artery, and obtaining the segmentation results of the hepatic artery. The method provided by the invention combines the threshold segmentation and regional growing strategies, achieves automatic segmentation, and is higher in instantaneity.
Description
technical field [0001] The invention mainly relates to the field of medical image processing and application, in particular to a hepatic artery segmentation method based on CT images. Background technique [0002] In the field of medical image processing and application, the application of CT images is more and more extensive. CT (Computed Tomography) image, that is, computerized tomography, uses precisely collimated X-ray beams, γ-rays, ultrasound, etc., together with highly sensitive detectors, to scan sections one by one around a certain part of the human body. It has the characteristics of fast scanning time and clear images, and can be used for the examination of various diseases. According to the different rays used, it can be divided into X-ray CT (X-CT), Ultrasound CT (UCT) and γ-ray CT (γ-CT). [0003] Among them, multi-slice spiral CT is widely used in clinical diagnosis, and its enhanced scan images are divided into three-phase sequence images of arterial phase,...
