Embodiment Construction

[0031] 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 invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0032] CT perfusion scanning is a commonly used enhanced scanning method. Usually, CT perfusion scanning can be divided into dynamic perfusion scanning and static perfusion scanning. Among them, dynamic perfusion scanning means that during the perfusion scanning process, the scanning table can reciprocate along the length of the scanning table. Movement, similar to a crib swinging back and forth...

Abstract

The present invention relates to a CT perfusion scanning method, system and storage medium, including obtaining the scanning length of the part to be scanned; determining the perfusion scanning mode according to the scanning length of the part to be scanned and the preset scanning length, and the perfusion scanning mode includes static Perfusion scanning and dynamic perfusion scanning; in the determined perfusion scanning mode, setting the number of scans and the scanning interval of the part to be scanned; performing perfusion scanning on the part to be scanned according to the determined number of scans and the scanning interval , which can prevent the scan interval manually selected by the user from being too large or too small, so that the set time interval for continuous scanning of the same part, that is, the scan interval, is more accurate. On the premise of ensuring that the image of CT perfusion scan is clear, it can be minimized. The number of consecutive scans of the same part reduces the amount of contrast agent absorbed by the patient, thereby reducing the harm to the patient.

Description

technical field [0001] The present invention relates to the field of CT scanning, in particular to a CT perfusion scanning method, system and storage medium. Background technique [0002] CT perfusion scanning is based on the principle of medical calculation of tracheal blood flow and the principle of central volume theorem and intravascular dilution to obtain the CT value of the region of interest on the CT image at a certain level at different times, thereby obtaining the time density curve, and using the perfusion software to process the perfusion value for diagnosis. [0003] Generally, perfusion scanning can be divided into dynamic perfusion scanning and static perfusion scanning according to whether the part to be scanned moves during the scanning process. Before scanning, the user can manually select the scanning method and set the time interval for continuous scanning of the same part. However, the time interval manually set is generally inaccurate, either too large...
