Abstract

The invention discloses a method for generating a positioning model, a method for performing bone positioning on a spine sagittal image, and a computing device for executing the above method. Wherein, the method for generating the localization model includes the steps of: obtaining a marked spine sagittal image as a training image, and the training image has corresponding labeled data; inputting the training image into a pre-trained localization model for processing, and the localization model includes volume A product processing layer, a classification processing layer and a regression processing layer, wherein the convolution processing layer performs convolution, activation and pooling processing on the input image to output at least one bone positioned, and the classification processing layer and the regression processing layer pair The located bones are subjected to classification and regression processing to output the predicted probability that the bone belongs to the sacrum and the predicted position of the bone; model training is performed on the pre-trained positioning model according to the labeled data to obtain the trained positioning model.

Description

technical field

[0001] The invention relates to the technical field of image processing, in particular to a method for generating a positioning model and a method for processing a spine sagittal image. Background technique

[0002] With the rapid development of computer technology and image processing technology, the use of computer technology to assist orthopedic precision surgery is gradually increasing. The most common application is Magnetic Resonance Imaging (MRI) imaging, from which a variety of physical property parameters of matter can be obtained, such as proton density, spin-lattice relaxation time T1, spin-spin Spin relaxation time T2, diffusion coefficient, magnetic susceptibility coefficient, chemical shift, etc., in order to apply it to the imaging diagnosis of various systems of the whole body. One of the main applications is spinal imaging to obtain sagittal images of the human spine, which can then be used in the diagnosis of various spinal diseases, such a...
