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 invention discloses a CT perfusion scanning method, system and storage medium, including obtaining the scan length of a part to be scanned; determining a perfusion scanning mode according to the scan length and the preset scan length of the part to be scanned, wherein the perfusion scanning mode includes a static perfusion scanning and a dynamic perfusion scanning; arranging the scanning timesand the scanning intervals of the part to be scanned in the determined perfusion scanning mode; processing the perfusion scanning for the part to be scanned according to the determined scanning timesand the scanning intervals, thereby being capable of avoiding the larger or smaller scanning intervals selected manually by users and making the arranged continuous scanning of time intervals namelythe scanning intervals of the same part to be more accurate. Under the premise of ensuring that images of the CT perfusion scanning are clear, the CT perfusion scanning method, system and storage medium can minimize the times of the continuous scanning of the same part as much as possible, reduce the amount of a contrast agent absorbed by patients, thereby reducing injuries to the patients.

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...
