Abstract

The present invention discloses a virtual endoscopy system based on a CT image. The system comprises: an image collection module configured to receive a plurality of CT images; an image processing module being in communication connection with the image collection module and configured to perform smooth processing and boundary processing of each CT image in the CT images transmitted by the image collection module; a three-dimensional conversion module being in communication connection with the image processing module and configured to perform surface reconstruction of each CT image after the processing through the image processing module to obtain a special three-dimensional image; a center line extraction module being in communication connection with the three-dimensional conversion module and configured to extract the center line of the special three-dimensional image; and a roaming module being in communication connection with the three-dimensional conversion module and the center line extraction module and configured to control the movement track of a virtual camera taking a center line as a viewpoint in the special three-dimensional image and perform roaming.

Description

technical field [0001] The invention relates to a medical image processing system, in particular to a medical image three-dimensional visualization system. Background technique [0002] With the development of modern medical imaging technology, modern medical equipment can help doctors diagnose internal organ or tissue lesions of patients without surgery. Computed tomography (CT) and magnetic resonance imaging (magnetic resonance MR) can produce data representing information about the internal organs of the human body. However, these data are often not given in a continuous three-dimensional form, they only form a series of tissue or organ sections, so only experienced doctors can correctly reconstruct the patient's internal organs and tissues, which gives Diagnosis introduces a great deal of subjectivity. [0003] Virtual endoscopy (Virtual endoscopy, VE) technology is a unique technology gradually formed with the intersection and integration of medical imaging technology...
