Abstract

The invention discloses a method and device for determining a medullary cavity anatomical axis based on deep learning, and the method comprises the steps: carrying out the segmentation of a two-dimensional cross section image according to a preset segmentation neural network, and obtaining a bone region corresponding to a medullary cavity through segmentation; performing layer classification on the bone area according to a preset classification neural network, and separating out a medullary cavity layer; determining central points of all medullary cavity layers according to a central point calculation formula; carrying out straight line fitting on the center point, and determining the medullary cavity anatomical axis. The invention aims to provide a high-precision medullary cavity anatomical axis determination mode.

Description

technical field [0001] The present application relates to the field of medical technology, in particular, to a method and device for determining the anatomical axis of the medullary cavity based on deep learning. Background technique [0002] Whether the anatomical axis of the medullary cavity can be accurately extracted in the medical field is an important factor affecting the success of some medical operations. For example, in total hip arthroplasty, the anatomical axis of the femoral medullary cavity and the anatomical axis of the tibial medullary cavity are two important anatomical axes. The anatomical axis of the femoral medullary cavity is a straight line passing through the femoral medullary cavity, and its direction determines the insertion position of the femoral intramedullary positioning rod in knee joint surgery. The tibial medullary canal anatomical axis is a straight line passing through the tibial medullary canal. At present, the method of determining the an...
