Problems solved by technology

In view of the large number of ribs, the fact that they are not running on the same plane, and the fractures are small and difficult to observe, the diagnostician often needs to observe repeatedly to prevent missed diagnosis and misdiagnosis, resulting in low diagnostic efficiency and heavy mechanical repetitive workload.

Embodiment Construction

[0062] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0063]The present invention starts from the perspective of image diagnosis and software implementation. The principle of implementation is to realize the interface of the automatic rib extraction algorithm first, and display the ribs in tiles, and include a single rib CPR (CPR: curved surface reconstruction) guide line in the tile display diagram. And the fracture marking point, according to the fracture marking point, it can switch...

Abstract

The invention discloses an image processing method and device based on a CT transverse image. The method a step of acquiring a plurality of CT transverse images, a step of generating a multi-planar reconstructed image based on the CT transverse images, a step of extracting a rib centerline from the multi-planar reconstructed image according to a rib contour, a step of forming a rib sleeve based onthe rib centerline, a step of straightening the rib sleeve and calculating pixels in the sleeve, and a step of carrying out the planarization display of a rib image in accordance with the calculatedpixels in the sleeve. According to the method, the rapid and effective diagnosis of a rib fracture is achieved, the repeated working intensity of a diagnosing doctor is reduced, the diagnosis time isreduced, the diagnostic accuracy is improved, and the method has high practicability and necessity in practical work.

Description

technical field [0001] The invention relates to the field of medical image display, in particular to an image processing method and device based on CT transverse images, and a rib image display system. Background technique [0002] With the development of society, more and more patients with thoracic trauma, CT is the most important and most effective examination method for diagnosing rib fractures. At present, the traditional CT diagnosis mode of rib fractures is mainly based on cross-sectional images, supplemented by three-dimensional images for positioning. Such as figure 1 As shown, the current diagnosis process using CT images is as follows: a. Browse through the cross-sectional images layer by layer and completely, find fractures and suspicious fractures and record them; b. After completely browsing the cross-sectional images, go to the VR image of the ribs, remove the bed board and scapula , locate the above-mentioned fractures and suspicious fractures on the VR imag...
