Rib unfolding device and method

Abstract

The invention belongs to the technical field of image processing, in particular to a rib unfolding device and method, aiming at solving the problems that the prior art is insensitive to small fractures and the calculation speed is slow. To this end, the present invention provides a rib unfolding method comprising obtaining a first specific plane corresponding to each specific point on a rib centerline based on a pre-acquired rib centerline; performing a polar coordinate transformation on a corresponding first specific plane based on a specific point on a rib centerline to obtain a second specific plane; obtaining pixel points with the largest pixel value corresponding to each specific angle in the second specific plane, connecting the pixel points with the corresponding specific points, and obtaining an expansion line corresponding to each specific angle; stitching the unfolding lines corresponding to all the specific angles in the second specific plane together to obtain the unfoldingimage of the ribs. Based on the above steps, the method provided by the invention has the advantages of accurate detection of small fractures in the ribs and high computational speed.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a rib expansion device and method. Background technique [0002] Radiology doctors often use CT images to detect rib fractures and rib metastases of cancer. The number of CT images for each patient may reach more than a hundred. In order to check the lesions and abnormalities in the CT images, doctors often need to check the CT images layer by layer, and track the dynamic changes of each rib on different layers of films. to visually track changes in rib cross-sectional area. The inspection of CT images is quite time-consuming, and in practical applications, manual inspection is likely to cause mistakes and miss fine fractures. [0003] By displaying the ribs in CT images in multiple dimensions, it is possible to eliminate the problems of missed fractures such as microfractures and fractures caused by rib occlusion during clinical diagnosis. Existing rib de...
