Abstract

The invention provides a lumen image unfolding and drawing method and a device. The method comprises steps of extracting a central line of a lumen from a three-dimensional lumen image and sampling the central line so as to obtain viewpoints; establishing a ball-shaped projection face for the viewpoints in the lumen, wherein points on the ball-shaped projection face correspond to points on the inner wall of the lumen; determining the corresponding relations between points on the two-dimensional projection face and the points on the inner wall of the lumen according to the corresponding relations between the points on the preset ball-shaped projection face and the points on the two-dimensional projection face; performing image drawing on the two-dimensional projection face so as to obtain the two-dimensional unfolded image of the three-dimensional lumen image according to the corresponding relates between the points on the two-dimensional projection face and the points on the inner wall of the lumen. According to the invention, the three-dimensional lumen image can be unfolded into a two-dimensional plane image and then drawn and the unfolded and drawn two-dimensional lumen image can comprise 360 degrees information of a virtual wandering position, so inner cavity information in front and back directions along the lumen in the current position can be directly displayed, image information is continuous and less in deformation, and doctors can easily observe the images and then make diagnoses.

Description

technical field [0001] The present application relates to the technical field of medical imaging, in particular to a method and device for unfolding and drawing a lumen image. Background technique [0002] With the emergence of medical imaging equipment such as CT (Computer Tomography, computer tomography), MRI (Magnetic-Resonance Imaging, nuclear magnetic resonance imaging), PET (Positron Emission Computer Tomography, positron emission computer tomography), and computer graphics, digital image processing technology With the development of modern information technology such as scientific visualization technology and virtual reality technology, virtual endoscopy technology, as a non-invasive inspection method, is more and more widely used. Virtual endoscopy technology is to obtain two-dimensional slice data of the human body through CT, MRI, PET and other medical imaging equipment, and process the collected data with the help of digital image processing, scientific visualizat...
