Embodiment

[0035] This embodiment provides a patient-oriented three-dimensional chest organ reconstruction method and system, including:

[0036] See the following paragraphs for specific steps.

[0037] · Step M1: Prepare the chest CT film for three-dimensional organ reconstruction, which is a set of medical digital imaging and communication files. Load the prepared chest CT movies as a 3D array.

[0038] ·Step M2, perform three-dimensional organ segmentation on the prepared chest CT film, and obtain the position and rough outline of the corresponding organ.

[0039]o Step M2.1: CT movie preprocessing. (1) The three-dimensional array of chest CT films is used to highlight and identify the pixel gray values ​​of different organs by using the image window levels used in film reading. For chest CT films, we use multiple window levels (bone window, lung window, mediastinum window) ) are processed simultaneously. (2) Normalize the gray value of each pixel between 0 and 1 to obtain a thre...

Abstract

The invention provides a method for performing aesthetic three-dimensional reconstruction in combination with a chest CT film and pre-modeling data. According to the method, an accurate and attractivethree-dimensional chest organ reconstruction output can be automatically generated from the chest picture input by the user in combination with a pre-prepared three-dimensional artistic model. Compared with a common CT deep learning segmentation reconstruction technology, due to the fact that the information of the three-dimensional artistic model is fully utilized, the problem that the final reconstruction effect is poor due to inevitable segmentation errors of the deep learning network can be relieved to a great extent, and the situation that the three-dimensional reconstruction effect is not ideal due to the fact that the layer thickness resolution ratio is poor on thick-layer CT input can also be relieved.

Description

technical field [0001] The present application belongs to the technical field of intelligent modeling, and in particular relates to a patient-oriented three-dimensional chest organ reconstruction method and system. Background technique [0002] Three-dimensional organ reconstruction is a three-dimensional figure formed by reorganizing the image by changing the original data matrix and field of view of the CT image, so as to play an irreplaceable role in the determination of the surgical plan, treatment plan and estimation. A method for reconstruction of 3D thoracic organs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a patient-oriented three-dimensional chest organ reconstruction method and system in order to solve the deficiencies in the prior art. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A patient-oriented three-dimensional chest organ re...
