Abstract

The invention discloses a three-dimensional reconstruction method and system based on medical image data, and the method comprises the steps: reading two-dimensional image data of computed tomography,carrying out the sampling of the two-dimensional image data, and obtaining the sampled two-dimensional image data; dividing a region of interest according to the sampled two-dimensional image data; performing three-dimensional reconstruction on the region of interest to obtain a reconstructed three-dimensional model; quantifying the reconstructed three-dimensional model to obtain surface area information and volume information of the region of interest; and generating three-dimensional model information corresponding to the region of interest including the surface area information and the volume information. According to the embodiment of the invention, three-dimensional reconstruction is carried out on the traditional medical image data to obtain the three-dimensional image of the medical image data, more visual image data can be provided, a more comprehensive image diagnosis mode is provided, and a powerful support is provided for application modes such as preoperative planning, intraoperative navigation, remote assistance and simulated surgery.

Description

technical field

[0001] The invention relates to the technical fields of medical image processing and computer image processing, in particular to a three-dimensional reconstruction method and system based on medical image data. Background technique

[0002] With the development of modern medical imaging technology, there have been computed tomography (Computed Tomography, CT), magnetic resonance imaging (Magnetic Resonance Imaging, MRI), positron emission computed tomography (Positron Emission Computed Tomography, PET), ultrasound and so on. However, these medical imaging devices can only provide two-dimensional images of internal tissues or organ sections of the human body, and cannot provide continuous three-dimensional images. In the current medical diagnosis, lesions are mainly found by observing a group of CT and MRI two-dimensional slice images, and the shape and size of lesions can only be estimated by the doctor's experience in film reading, which lacks intuitiveness ...
