The invention discloses a method for setting contrast agent parameters. For example, the method can include the steps that weight parameters of scanned objects are collected; scan protocols corresponding to scanned parts of the scanned objects are inquired from a protocol library built in advance, wherein one or more scanning protocols corresponding to the different scanned parts respectively are saved in the protocol library, and the contrast agent parameters corresponding to the different weight parameters respectively are saved in the scanning protocols; and the contrast agent parameters corresponding the collected weight parameters are extracted from the inquired scanning protocols. According to the method for setting the contrast agent parameters, the corresponding scanning protocols can be inquired according to the scanned parts of the scanned objects, after the weight parameters of patients are collected, the contrast agent parameters corresponding to the weight parameters are extracted from the inquired scanning protocols, and therefore the aim of automatically selecting the standard contrast agent parameters for users without depending on the experience of the users is achieved. In addition, the invention further discloses a device for setting the contrast agent parameters and a CT system.
Description
technical field [0001] The present invention relates to the field of CT, in particular to a method and device for setting contrast agent parameters and a CT system. Background technique [0002] CT, computerized X-ray tomography. Enhanced scanning, one of the CT scanning techniques, is applied to the scanning of "contrast agent" in blood vessels. The iodine-containing organic compound, that is, contrast agent, is injected intravenously to maintain a certain level of iodine in the blood, and the images of organs and lesions are enhanced to show more clear. [0003] At this stage, parameters such as the dose size and injection rate of the contrast agent are manually set according to the doctor's experience. For doctors with insufficient clinical experience, the dose of contrast agent may be too large or too small, and the injection rate may be too fast or too slow, which will make the quality of CT scanning images unsatisfactory, and may even increase the side effects on the...
