Rib display method and device

Abstract

The embodiment of the invention provides a rib display method and device, and the method comprises the steps of carrying out the tissue segmentation processing of a chest three-dimensional scanning image, obtaining a three-dimensional rib image in the chest three-dimensional scanning image, wherein the three-dimensional rib image comprises at least one pair of ribs, and the at least one pair of ribs comprise a left rib and a right rib which are matched with each other; based on the three-dimensional rib image, extracting rib center lines of the ribs, wherein each center point on the rib center lines is located in the center of the rib section; for each central point, sampling processing along the target direction of the central point, determining rib pixel points in the three-dimensional rib image, wherein the target direction is the radial direction of a rib section corresponding to the central point; and generating a two-dimensional rib display image based on the rib pixel points. The ribs can be automatically displayed on a two-dimensional plane under the condition that the basic bending deformation of the ribs is reserved, the diagnosis time can be saved, and the workload of doctors is reduced.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of image processing, and in particular to a rib display method and device. Background technique [0002] Ribs are the bony support of the thorax, in the shape of an arc tube, connecting the sternum and the spine, and play an important role in protecting the human chest cavity and heart. Rib fracture is a common chest trauma disease. Clinically, CT (Computed Tomography, computerized tomography) technology is generally used to obtain chest fracture CT images, and doctors diagnose fracture trauma based on fracture CT images. In the process of trauma analysis or fracture analysis, due to the large number of CT image layers, it takes a long time to directly find the fracture area in the three-dimensional CT image or MPR (multi-planar reconstruction, multi-directional reconstruction) image. In addition, due to the special arc-shaped structure of the ribs, the inner area of ​​the ribs in...

Problems solved by technology

In the process of trauma analysis or fracture analysis, due to the large number of CT image layers, it takes a long time to find the fracture area directly in the 3D CT image or MPR (multi-planar reconstruction, multi-directional reconstruction) image

In addition, due to the special arc-shaped structure of the ribs, the inner area of ​​the ribs in the above image is easily covered, and minor fractures and fractures are easily missed.

[0003] In the existing technology, when the rib image is displayed in two dimensions, the ribs are straightened and displayed, and the relative position and orientation of each rib cannot be accurately displayed, and the appearance of the rib image is unnatural.
