Method and system of enhancing display of computed tomography (CT) postprocessing image

Abstract

Provided are a method and a system of enhancing the display of a computed tomography (CT) postprocessing image. The system is used for projecting and displaying a stereoscopic CT postprocessing image, and comprises an image processing module, a stereo image generator, a projector, an image control signal projector, stereoscopic glasses and a projection screen. The image processing module is used for processing an original CT postprocessing image, and generates an image pair corresponding to a left eye and a right eye which are used as the input signal of the stereo image generator. The stereo image generator is used for achieving the generating and controlling of stereo images and outputting generated continuous CT postprocessing image signals to the projector. The projector projects virtual stereo images on the projection screen, and meanwhile the image control signal projector transmits stereoscopic control signals to control the opening and the closing of the shutter of the stereoscopic glasses in sequence. The method and the system of enhancing the display of the CT postprocessing image enhance the CT postprocessing image to three-dimensional virtual display from two-dimensional flat panel display, and eliminate the adverse impact of the overlapping of images on the observation of pathological changes.

Description

technical field [0001] The present invention relates to the field of medical technology, in particular to a method and system for enhanced display of CT post-processing images, more precisely, a method and system for virtual three-dimensional reconstruction of CT post-processing images. Background technique [0002] Post-processing of CT images has received more and more attention due to the ability to display three-dimensional images on the screen. However, although the post-processing technology of CT can create a three-dimensional image, which contains the information of the three coordinate axes of the image, the output is still on the flat monitor screen or film, and the image presented to the doctor is actually three-dimensional. The projection of an image on a two-dimensional plane, that is, in the three-dimensional model on the monitor screen or film, displays the information of the X-axis and Y-axis of the image, and cannot display or superimpose the information of ...

Problems solved by technology

However, methods that can provide spatial stereoscopic display, such as virtual reality methods, are mostly used in surgical simulations. There are no reports of virtual reality methods being used for CT diagnosis. In addition, most of the existing methods for successful application of virtual reality are expensive and require relatively high technical requirements. High, not suitable for promotion
