Abstract

The invention relates to a CT scanning method, and the method comprises the steps: obtaining a real-time monitoring image of a region of interest after a contrast agent is injected, and the region of interest at least comprises a first target region and a second target region; acquiring a CT value change condition of the region of interest based on the real-time monitoring image; and performing CT scanning on the region of interest based on the CT value change condition. According to the method and the device, the problems that in multi-phase or multi-part enhanced scanning in related technologies, a traditional threshold tracking technology can only measure the CT value of one part or phase to determine the scanning time, and other parts or phases can only be judged depending on experience and are not accurate enough are solved. According to the method, the scanning triggering time point with the best scanning effect of each part can be accurately determined in multi-part or multi-phase enhanced scanning, the optimal image data can be obtained, and the risk of dosage increase caused by repeated scanning due to inaccurate scanning triggering time points can be avoided.

Description

technical field [0001] The present application relates to the technical field of medical imaging, in particular to a CT scanning method, device, electronic device and storage medium. Background technique [0002] Computer tomography (Computed Tomography, CT) uses precisely collimated X-ray beams, γ-rays, ultrasound, etc., together with highly sensitive detectors, to conduct cross-sectional scans one after another around a certain part of the human body. Fast, clear images, etc., can be used for the examination of various diseases; according to the different rays used, it can be divided into: X-ray CT (X-CT) and γ-ray CT (γ-CT). [0003] CTA is the abbreviation of CT angiography (CT angiography). Spiral CT scanning is performed after intravenous injection of contrast agent. During 3D reconstruction, structures that do not need to be displayed, such as skin, muscle, and bone, are removed, and only the 3D vascular structure and visceral structure are displayed. CTA has been Wi...
