Problems solved by technology

However, at present, people are still limited to the traditional way of thinking of cross-sectional scanning, and have not explored from the longitudinal section of the nerve. Therefore, so far, no imaging method has overcome this difficulty.

Embodiment 1

[0033] [Example 1] Chiropractic Medical Imaging

[0034] The spinal nerves in the human body are in the shape of round cords, running and branching in three-dimensional space like branches, from thick to thin, but their running and branches are similar to straight lines, with varying degrees of arc performance. On the long axis of their travel, they can appear on the same plane at least once. There are more opportunities for spinal nerves that run in a straight line to appear on the same plane. In addition, the sectional shape of the spinal nerve on the same plane must also be in the shape of a cord.

[0035] According to the above-mentioned characteristics of the spinal nerve, the present invention uses the multi-plane reconstruction function of multi-slice spiral CT (that is, it can be imaged on any two-dimensional plane), and first performs volume scanning on the spinal nerve tissue to be scanned to obtain volume data; The thin-slice scanning function of spiral CT (that i...

Embodiment 2

[0054] [Example 2] Tendon and ligament imaging of knee joint

[0055] At present, multi-slice spiral CT is widely used in the examination of the knee joint, but the medical imaging of the ligaments and tendons in this part has not yet achieved satisfactory results. Using the same-layer display imaging method provided by the present invention, through the improvement of scanning parameters and the same-layer display and reconstruction post-processing technology of the tendons and ligaments of the knee joint, the cable running of the ligaments and tendons can be displayed in the longitudinal section, and the images are clear. The degree and clinical application value are obviously different from conventional CT and MR (nuclear magnetic resonance) examinations, which can effectively solve this problem.

[0056] The preparations before CT scanning, the parameter selection during CT scanning, and the image processing after CT scanning will be described separately in the following s...

Abstract

Human body ropy tissue same layer display imaging method based on multislice spiral CT is disclosed in the present invention, comprising the following steps: a, using the multislice spiral CT to process volume scanning; b, using the multislice spiral CT thin-layer scanning function to regulate CT into two-dimension plane being tangent with a plane of ropy tissue courser, to obtain one or more longitudinal sections of spinal nerve; c, using multislice spiral CT three-dimension reconstructive function to combine each longitudinal section into medical image of the ropy tissue by geometric operation. The present invention changes the ropy anatomizing tissue difficult to image by its three-dimension spacial courser into two-dimension spacial plane pattern to display, especially suitable for medical imaging of human body spinal nerve, tendon, and ligament tissue. By the present invention, the ropy tissue cross section difficult to quantitative analysis can realize to integral morphology embodiment, thereby to provide credible quantitative index to clinical diagnose.

Description

technical field [0001] The present invention relates to an imaging method suitable for human internal cord-like tissue, in particular to a method for displaying and imaging human internal cord-like tissue such as spinal nerves, tendons, and ligaments in the same layer by using multi-layer spiral CT, which belongs to medical science. field of imaging technology. Background technique [0002] CT is the abbreviation of Computerized Tomography, which is divided into conventional CT and multi-slice spiral CT. Conventional CT has the defects of slow scanning speed and poor imaging effect, and has been gradually replaced by multislice spiral CT (MSCT). Multi-slice spiral CT was applied clinically in the second half of 1998, which is another important milestone in the history of CT since slip ring (spiral) technology. [0003] Multi-slice helical CT scans three-dimensionally to collect data through horizontal axis for reconstruction in various directions. Three-dimensional scanni...
