Vascular imaging method and device

Abstract

Embodiments of the invention disclose a vascular imaging method and device. The method includes: scanning an area of blood vessels to be detected to obtain a plain scan image and an enhanced image, and subtracting the enhanced image according to a skeletal area in the plain scan image to obtain a subtracted image; detecting a vascular area of the blood vessels to be detected, in the enhanced image; fusing the vascular area of the blood vessels to be detected, in the subtracted image to obtain an image of the blood vessels to be detected. Therefore, by the use of the vascular imaging method and device, the blood vessels passing skeleton can be retained in the subtracted image.

Description

technical field [0001] The invention relates to the technical field of medical images, in particular to a blood vessel developing method and device. Background technique [0002] Vascular disease is one of the diseases that seriously affect human health. Therefore, the requirements for vascular imaging technology are getting higher and higher. Due to the complex shape and structure of blood vessels in the human body, some blood vessels are blocked by bones, and it is difficult to display them intuitively in the 3D volume rendering results. The overall shape and structure of blood vessels. For example: head and neck blood vessels start from the heart and enter the brain through the bone area at the bottom of the skull, carotid arteries pass through the skull, vertebral arteries pass through the six vertebrae and enter the interior of the skull, etc. [0003] At present, the subtraction technique is usually used to subtract the bone area in the image so as to preserve all the...

AI Technical Summary

Problems solved by technology

The implementation of the existing subtraction technology requires two scans of the patient, and in the second scan, the patient needs to be injected with a contrast agent, which results in a longer time interval between the first scan and the second scan

Since it is difficult for the patient to maintain the same body position for a long time, the detected area of ​​the patient will be displaced during the two scans, which will cause the problem that the part of the blood vessel passing through the bone is mistaken for the bone area and subtracted. Therefore, using the existing subtraction Subtraction images generated by shadowing technology cannot accurately and completely display the structure of the vascular region
