Problems solved by technology

[0003] Because in this case, the bone structure of the affected side is often partially damaged or missing, it is difficult to infer the precise morphological characteristics of the pre-injury bone based on the existing bone shape of the affected side alone

Embodiment Construction

[0054] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below in conjunction with the examples and accompanying drawings, but this does not constitute a limitation to the present invention.

[0055] figure 1 with figure 2 They are the stand-alone mode operation scene and the remote mode operation scene of the system of the present invention respectively. The system processes and analyzes bilateral target bone images from the same patient to restore bone defect morphology and parameter measurement. Among them, the medical imaging apparatus is used by a user to obtain medical images by scanning or imaging a patient. Different medical imaging modalities supporting DICOM standard can be used in this system. For example, medical images may be computed tomography (CT) images and MRI images or any image from a suitable image or data acquisition device.

Abstract

The invention discloses a measuring method and system for single-side osteal damage of the human body. The corresponding osteal form at the uninjured side serves as a template, a 3D osteal CT image of the uninjured side is overturned to form a mirror image, and a 3D osteal CT image of the injured side is subtracted from the mirror image to obtain the accurate form of osteal defect at the injured side; and the parameters including the maximal length, width, depth and spatial position of the osteal defect position are measured to make comprehensive evaluation for the osteal defect of the injured side. Model reconstruction and 3D measurement are realized for single-side osteal defect of human body, the osteal defect can be evaluated accurately and comprehensively, and the method and system have great significance in effectively reducing the post-operation recurrence rate caused by the osteal defect.

Description

technical field [0001] The invention belongs to the field of computer-aided medicine, and in particular relates to a method and a system for measuring skeletal bone damage of one side of a human body. Background technique [0002] Many orthopedic patients have unilateral limb bony injuries and partial bony structural defects due to various reasons such as trauma, strain, tumor or autoimmune diseases. In such cases, reconstruction of the defective bone structure is often required in order to restore the function of the affected limb. At this time, only by accurately understanding the morphological characteristics of the bony structure at the defect site can the surgical reconstruction method be effectively planned. [0003] Because in this case, the bone structure of the affected side is often partially damaged or missing, it is difficult to infer the precise morphological characteristics of the pre-injury bone based on the existing bone shape of the affected side alone. At...
