Problems solved by technology

However, if the position of the blood vessel changes during the scanning process, there may be a phenomenon that the monitored ROI area cannot completely contain the blood vessel, which makes the tracking scan accuracy of the blood vessel poor, resulting in the failure of the blood vessel tracking scan

Embodiment Construction

[0030] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0031] In vascular imaging, contrast agent tracking scanning technology can be used to enhance the image observation effect of blood vessels. The example of the present disclosure provides a contrast agent tracking scan method, so as to make the tracking of the blood vessel to be monitored more accurate. figure 1 An example contrast agent tracking scan method is provided, including: ...

Abstract

The invention provides a contrast medium tracking scanning method and device. The method comprises the steps that in a tracking layer image of one-time contrast medium tracking scanning, an inner blood vessel region inside a preset monitoring region in the tracking layer image is recognized; according to the inner blood vessel region, an outer blood vessel region outside the monitoring region is obtained, and the outer blood vessel region and the inner blood vessel region conform to region continuity; the whole of the inner blood vessel region and the outer blood vessel region is determined asa target blood vessel region; the contrast medium concentration value of the target blood vessel region is monitored, and if the contrast medium concentration value reaches a target concentration value, conventional scanning is started; if the contrast medium concentration value does not reach the target concentration value, next contrast medium tracking scanning is executed so as to determine the target blood vessel region again. The blood vessel contrast medium tracking is more accurate.

Description

technical field [0001] The present disclosure relates to medical imaging technology, in particular to a method and device for contrast agent tracking scanning. Background technique [0002] Contrast agent tracking scanning (Bolus Tracking) is a technique used in computed tomography to show blood vessels more clearly. Among them, contrast agent (also known as contrast agent, contrast media) is one of the most commonly used drugs in interventional radiology operations. It is a chemical product that is injected (or taken) into human tissues or organs to enhance the effect of image observation. It is mainly used clinically for vascular imaging and diagnosis of various diseases. [0003] In the current CT (Computer Tomography, X-ray computed tomography) system, taking the use of contrast agent tracking scanning technology in vascular imaging as an example, the contrast agent is generally injected into the patient's body and an ROI (region of interest) is drawn. The ROI area may...
