Abstract

The invention relates to a method for assessing a visual technology of a virtual colonoscopy by using visual area. The method comprises: acquiring a slice image of a clinical CT colon; processing the slice image to complete segmentation on colon tissues; creating a three-dimensional colon model according to the segmented colon tissues; extracting a center line of the three-dimensional colon model, and averagely dividing the three-dimensional colon model into a left half part and a right half part along the center line; acquiring the visual area of the three-dimensional colon model of the left half part and the right half part respectively; comparing the visual area with all surface area of the three-dimensional colon model, and assessing the visual technology of the virtual colonoscopy according to the comparison result. By acquiring the visual area of the three-dimensional colon model and comparing the visual area with all the surface area of the three-dimensional colon model, the visual technology can be assessed more accurately, the obtained result is more precise, and errors are greatly reduced.

Description

technical field [0001] The invention belongs to the field of clinical medicine colon, in particular to a method for evaluating virtual colonoscope visualization technology by using a visualization area. Background technique [0002] Virtual colonoscopy generally adopts fly-through visualization technology. In order to simulate the detection idea of ​​optical colonoscopy, this technology uses a virtual camera (generally with a viewing angle of 90-120 degrees) along the calculated three-dimensional centerline, surface rendering technology, and real To reproduce the situation inside the colorectum, the direction of observation can start from the rectum (antegrade), or from the cecum (retrograde). [0003] Visualization technology is evaluated through the observation of Fly-through technology and Fly-over technology. However, the means used in the prior art to evaluate visualization technology are mostly inaccurate and have errors. Contents of the invention [0004] The techn...
