Embodiment 1

[0057] Embodiment 1, data processing: CT chest plain scan sequence image, convert dicom format to nii format. Spine area target detection: Use the image data processed in the previous step to detect the spine area. In order to reduce the influence of useless information and improve the speed and accuracy of segmentation, the coordinate position of the spine area detected in the second step is expanded by 10 pixels in each direction for cropping, and the cropped data is used as the input data for the next step of segmentation, and the cropped data It can completely contain the spine area, and at the same time contain a small part of the surrounding information. Spine region segmentation: Use the regular data cut out in the previous step to enhance the data (image normalization, flipping, etc.), and then input it to the 3D Unet segmentation model for segmentation. The cut data is relatively small, and the downsampling is set The feature extraction network with a size of (16, 16...

Abstract

The invention relates to the field of bone mineral density measurement, in particular to a bone mineral density measurement method and system, a storage medium and electronic equipment. The method comprises the following steps: step 1, carrying out spine area detection on a CT chest plain scanning sequence image through an optimized target detection algorithm to obtain a spine area image; step 2, inputting the spine region image into a spine segmentation model for segmentation to obtain a segmentation result; step 3, processing the segmentation result to obtain a cancellous bone region; and step 4, training a regression bone mineral density detection model based on the cancellous bone area, and inputting an image to be measured into the regression bone mineral density detection model to obtain a bone mineral density value. The method can achieve the effects of higher efficiency and higher accuracy.

Description

technical field [0001] The invention relates to the field of bone density measurement, in particular to a bone density measurement method, system, storage medium and electronic equipment. Background technique [0002] Bone density is an important indicator of bone quality. The degree of osteoporosis is an important basis for predicting the risk of fracture. Bone density examination can help detect whether there is calcium deficiency, so that by adjusting the diet, children can be supplemented with calcium in time to ensure normal bone development. Through the evaluation of bone density, the absorption and intake of bone-forming raw materials during the growth and development process can be determined, and the internal and external factors that may affect its growth and development can be analyzed, so as to formulate targeted nutrition and exercise programs in a timely manner. The measurement scheme for bone density in the prior art is too complicated, and the efficiency of ...
