Abstract

The invention discloses a visualization method and device for enhancing depth perception in 2D / 3D image fusion. The depth perception in 2D / 3D image fusion display can be enhanced, an observer can moreeasily perceive and understand a three-dimensional structure, the method can be used for a preoperative planning and interactive navigation module in a B-type aortic dissection precise intracavitaryrepair operation navigation system, and important and accurate visual information is provided for the navigation system. The method comprises the following steps of: (1) acquiring a three-dimensionaldata field; (2) preprocessing the data; (3) classifying the data; (4) acting depth color coding on color information of the sampling points; (5) applying edge contour enhancement to sampling point transparency information; and (6) obtaining the color of the final rendered image through image synthesis.

Description

technical field [0001] The present invention relates to the technical field of medical image processing, in particular to a visualization method for enhancing depth perception in 2D / 3D image fusion, and a visualization device for enhancing depth perception in 2D / 3D image fusion, which can be used for precise cavity of type B aortic dissection Preoperative planning and interactive navigation modules in the endoprosthetic surgery navigation system can shorten the operation time and reduce the radiation to the patient and staff. Background technique [0002] X-ray images remain the real-time imaging modality of choice for most surgical interventions. To assist interventionalists during surgery, preoperative images can be fused with X-ray images. This 2D / 3D overlay is obtained by an alpha blending method, that is, a compromise is made on the transparency between the data. [0003] Despite this shortcoming, this fusion modality remains a gold standard and is widely used in endo...
