Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0057] The present invention provides a method for automatic positioning of vertebrae and intervertebral discs. Firstly, the rough positioning area of ​​vertebrae and intervertebral discs is obtained, and the edge image of the vertebra is obtained according to the rough positioning area, and then the horizontal position of the intervertebral disc is determined in the image of the edge of the vertebrae. , and determine the upper and lower edge positioning lines of the vertebrae between the two adjacent intervertebral discs according to the horizontal position of the two adjacent intervertebral discs, and finally determine the vertical distance between the two adjacent vertebrae according to the upper and lower edge positioning lines of the two adjacent ver...

Abstract

The invention disclose a method for positioning vertebras and intervertebral discs, comprising the following steps of: determining the rough positioned zones of the vertebras and intervertebral discs in a positioned image; generating a vertebra edge image according to the rough positioned zone; determining the horizontal position of each intervertebral disc on the vertebra edge image; and determining the horizontal position of each intervertebral disc according to the vertebra edge image and determining the upper edge positioning line and the lower edge positioning line of each vertebra and the positioning line of each intervertebral disc. Meanwhile, the invention also discloses a device for positioning the vertebras and the intervertebral discs. By adopting the method and the device in the invention, the positioning speed and precision of the vertebras and the intervertebral discs can be improved.

Description

technical field [0001] The invention relates to computerized tomography (CT, Computed Tomogramgy) technology, in particular to a method for positioning vertebrae and intervertebral discs and a positioning device for vertebrae and intervertebral discs. Background technique [0002] In clinical applications, it is sometimes necessary to use a CT scanner to scan the vertebrae and intervertebral discs. Before scanning, the vertebrae and intervertebral discs to be scanned need to be positioned to determine the scanning area of ​​the vertebrae and intervertebral discs. In the prior art, the location method of vertebrae and intervertebral disc is: at first the X-ray tube of CT scanner is placed in the required angle (front position or lateral position) and is fixed, then the patient is sent into the frame of CT scanner and perform a series of X-ray exposures to obtain images of the patient's entire body. We call this image a scout image; the doctor observes the vertebrae or interve...
