Problems solved by technology

[0004] However, in related technologies, when performing three-dimensional reconstruction of liver CT images, the same reconstruction process is used for different tissue parts of the liver, resulting in low reconstruction efficiency and poor reconstructed image quality, which cannot meet the needs of doctors.

Abstract

The invention provides a method for three-dimensional reconstruction of a liver computed tomography (CT) image. The method comprises the steps of segmenting a liver two-dimensional CT image sequence, respectively extracting segmentation sequences corresponding to every tissue in a plurality of tissues of the liver; and performing three-dimensional image reconstruction on every tissue according to the segmentation sequences according to every tissue and three-dimensional reconstruction processes corresponding to every tissue so as to perform three-dimensional reconstruction on the liver CT image. According to the technical scheme, when the three-dimensional reconstruction is performed on the liver CT image, the corresponding reconstruction processes can be selected according to the characteristics of different tissues, and accordingly reconstruction efficiency of the liver CT image and quality of the liver CT three-dimensional reconstruction image are improved.

Description

technical field [0001] The invention relates to the field of digital medicine, in particular to a method for three-dimensional reconstruction of liver CT images. Background technique [0002] With the development of computer technology, 3D reconstruction technology based on CT (Computed Tomography, computerized tomography) images is widely used in surgical operations, such as preoperative planning, surgical simulation, and preoperative risk assessment. [0003] In traditional hepatobiliary surgery, doctors can only conduct disease diagnosis and surgical planning based on the results of two-dimensional CT scans. Diagnosis and surgical planning based on two-dimensional CT scan results are far from enough. Therefore, it is urgent to establish an intuitive and three-dimensional three-dimensional display results to guide the operation. With the help of the 3D reconstruction results of liver CT, doctors can intuitively obtain the positional relationship between hepatic veins, hep...
