Problems solved by technology
[0002] Hip X-ray images are one of the conventional medical images. At present, the analysis of hip X-ray images is mostly done manually, and there is no effective automatic analysis solution.
[0003] However, the shortcomings of the manual method are: on the one hand, the analysis takes a long time and the efficiency is low; on the other hand, the accuracy of the analysis results depends on the professional level of the analyst, so it is difficult to guarantee the accuracy of the analysis results

The invention discloses a fast automatic analysis method of hip joint X-ray images, which comprises the following steps: obtaining hip joint X-ray images marked with N key points in advance; For a series of hip X-ray images collected in advance, according to the key point location, taking a certain area centered on the key point location as a target area, that is, N different target areas are selected for a hip X-ray image; training A 2D convolutional neural network for hip joint target region detection. During the test, inputting the hip X-ray images to be analyzed to 2D convolutional neuralnetwork, outputting the predicted target regions and their categories, and calculating the center point of each predicted target region as the key point. Through the above-mentioned method, the automatic analysis of hip X-ray images can be realized quickly and accurately.
Description
Technical field [0001] The invention relates to the technical fields of machine learning and intelligent medical image analysis, and in particular to a method for rapid and automatic analysis of hip joint X-ray images. Background technique [0002] The X-ray image of the hip joint is one of the conventional medical images. At present, the analysis of the X-ray image of the hip joint is mostly done manually, and there is no effective automatic analysis scheme. [0003] However, the shortcomings of the manual method are: on the one hand, analysis is time-consuming and inefficient; on the other hand, the accuracy of the analysis results depends on the professional level of the analyst, so it is difficult to guarantee the accuracy of the analysis results. Summary of the invention [0004] The purpose of the present invention is to provide a fast and automatic analysis method for hip joint X-ray images, which can quickly and accurately realize automatic analysis of hip joint X-ray images...
