Problems solved by technology

The automatic rib fracture detection algorithm based on deep learning is currently being explored by various companies. However, due to the invisibility of some rib fractures, the artificially marked labels are not very accurate. It is true positive, but there are some false negatives for the ribs with normal markers, which will seriously affect the performance of the model, and there will be false detection and missed detection.
[0004] In summary, the accuracy and efficiency of the existing rib fracture detection technology are very low

Abstract

The invention discloses a fracture detection method and device which are used for improving fracture automatic detection accuracy and working efficiency. The invention provides the fracture detectionmethod. The method comprises the steps that each rib detection frame of a thoracic cavity image of a fracture patient is determined; the probability value of rib fracture in each rib detection frame is determined; and based on the probability value of the rib fracture in each rib detection frame, a fracture detection result is output, wherein the fracture detection result comprises rib detection frame information used for indicating whether the rib is fractured or not.

Description

technical field [0001] The present application relates to the technical field of medical image processing, in particular to a fracture detection method and device. Background technique [0002] When the chest is subjected to direct or indirect stress, rib fracture is the most common symptom, accounting for about 90% of thoracic fractures. Children's ribs are elastic and not easy to break, while adults, especially the elderly, have weakened rib elasticity and are prone to fractures; Therefore, with the aggravation of aging, the number of patients with rib fractures will show a rising trend. Computed Tomography (CT) images are currently commonly used in the diagnosis of rib fractures in clinical practice. They have the advantages of large-scale, thin-slice, and high-resolution, and can effectively display the whole rib or 3 / 4 of the rib, avoiding the risk of X-ray fractures. Some lesions are blurred and difficult to diagnose accurately due to overlapping images of lesions in ...
