Pelvic bone correction method, operation system, storage medium and electronic equipment

Abstract

The invention provides a calculation method and an operation system for correcting pelvic bone based on left and right anterior superior spine and pubis combined central points, and the method comprises the steps: marking the pelvic bone on a CT original image, and marking the left and right anterior superior spine and pubis combined central points on a pelvic bone 3D model segmented by a neural network; and the pelvic bone is rotated around the X axis, the Y axis and the Z axis for three times in any sequence so as to be corrected, so that the auxiliary preoperative planning of a surgical robot is facilitated. When the neural network is used for automatic segmentation, an original image file obtained after normalization and binarization processing is conducted on an input original image is input into the network model stored before to be trained. Wherein for the part with the channel number of 32, while the channel number is kept unchanged, add is used instead of concat, so that the information amount under the features of the image at the moment is increased, the parameter and calculation overhead can be saved, and the final image classification is facilitated.

Description

technical field [0001] The present invention relates to the technical field of image data processing, more specifically, to a method and system for pelvic image correction based on deep learning, numerical algorithms, etc. A method and system for center point straightening of the pelvis. Background technique [0002] With the rapid development of modern society, all walks of life have begun to have an inseparable relationship with the IT industry, and the same is true for the medical industry. In total hip replacement surgery assisted by surgical robots, preoperative planning is a very important step. It can be said that whether the preoperative planning is good or not can directly affect the final result of the operation, and the correctness of the pelvic position is an important step in preoperative planning. [0003] In the process of CT (computed tomography) shooting, the patient's prone position is different in most cases according to his own condition. If it cannot be...

Problems solved by technology

[0003] In the process of CT (computed tomography) shooting, the patient's prone position is different in most cases according to his own condition. If it cannot be parallel to the plane formed by the X-axis and Z-axis, it will cause the whole CT to be distorted. Orientation is in a misaligned condition, preventing surgery from being performed correctly
