Abstract

The embodiment of the invention provides a three-dimensional reconstruction method and device for a blood vessel image. The method comprises the following steps: segmenting a three-dimensional chest image by adopting a level set method to obtain a two-dimensional lung image; obtaining a mask image of a lung blood vessel according to the two-dimensional lung image; performing interpolation calculation on the mask image to obtain a complete lung blood vessel image; and performing volume rendering on the lung blood vessel image to obtain a three-dimensional lung blood vessel image. According to the embodiment of the invention, a pulmonary vessel tree can be established to assist a doctor in avoiding vessels as much as possible when determining an operation scheme, so that damage to the vessels is reduced.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a method and device for three-dimensional reconstruction of blood vessel images. Background technique [0002] Affected by factors such as air pollution and smoking, lung diseases have seriously endangered human health and life. When planning lung surgery clinically, doctors hope to observe the shape and spatial position of some important tissues such as blood vessels, diseased bodies, and sensitive tissues in the lungs, and then determine a scientific surgical plan. [0003] At present, the clinical diagnosis of the lungs mostly uses two-dimensional tomographic images, but the two-dimensional tomographic images cannot provide an intuitive lung structure for medical diagnosis, especially the pulmonary blood vessels are small in size and low in contrast compared with other lung tissues, and The bronchi interlaced with the lungs, and the structure is complex. Ther...
