Problems solved by technology

[0004] However, due to the wide variety of clinical diagnoses, it is a cumbersome and time-consuming process to select a suitable scanning protocol from various pre-established scanning protocols only by combining the doctor's medical certificate.
In addition, once the positioning plain film scanning of clinical patients is completed, if the CT equipment operator spends more time on subsequent scanning protocol selection, it will increase the possibility of the patient’s position moving during this period, which will lead to Affect the accuracy of subsequent scanning positioning

Embodiment 1

[0051] refer to figure 1 , figure 1 The flow chart of the scanning protocol setting method provided in this embodiment may specifically include:

[0052] S101: Acquire any plain film positioning image.

[0053] In this embodiment, firstly any plain film positioning image is acquired, specifically, the plain film positioning image may be obtained by scanning the plain film of the patient.

[0054] S102: Receive any point of interest, line or area on the plain film positioning image input by a user.

[0055] In this embodiment, after obtaining the plain film positioning image, the user determines a point of interest, line of interest, or region of interest (English: Region Of Interest, abbreviated as Region Of Interest) on the plain film positioning image through an input device such as a mouse according to requirements : ROI). Wherein, the point of interest, the line of interest or the region of interest is the target or the vicinity of the target that the user expects to s...

Embodiment 2

[0077] refer to image 3 , image 3 The flow chart of the method for setting the scanning protocol provided in this embodiment, the method includes:

[0078] S301: Acquire any plain film positioning image.

[0079] S302: Receive any point of interest, line or area on the plain film locating image input by a user.

[0080] S303: Generate a region to be matched according to the interest point, line or region.

[0081] S304: Determine whether there is a reference image whose matching degree with the region to be matched is greater than a preset threshold among the pre-stored reference images.

[0082] S305: Acquire the reference image when there is a reference image whose matching degree with the region to be matched is greater than a preset threshold.

[0083] S306: When there is more than one reference image whose matching degree with the region to be matched is greater than a preset threshold, obtain the matching degree between the reference image and the region to be matc...

Embodiment 3

[0095] refer to Figure 5 , Figure 5 A schematic structural diagram of a scanning protocol setting device provided in this embodiment, the device may include:

[0096] The first acquisition module 501 is configured to acquire any plain film positioning image;

[0097] A receiving module 502, configured to receive any point of interest, line or area on the plain film positioning image input by the user;

[0098] A generation module 503, configured to generate a region to be matched according to the point of interest, line or region;

[0099] A judgment module 504, configured to judge whether there is a reference image whose matching degree with the region to be matched is greater than a preset threshold in the pre-stored reference images;

[0100] The second acquisition module 505 is configured to acquire the reference image when the judging module determines that there is a reference image whose matching degree with the region to be matched is greater than a preset thresho...

Abstract

The invention discloses a setting method and device of a scanned protocol. The method comprises the steps that any flat piece locating image is obtained; any interest point or line or zone input by a user on the flat piece locating image is received; according to the interest point or line or zone, a zone to be matched is generated; whether a standard image with the matching degree with the zone to be matched larger than a preset threshold value exists in pre-stored standard images is judged; when a standard image with the matching degree with the zone to be matched larger than the preset threshold value exists, the standard image is obtained; in the corresponding relation of preset standard images and scanned protocols, a scanned protocol corresponding to the standard image is obtained; and when a scanned protocol corresponding to the standard image exists, setting of the scanned protocol is completed. The setting time of the scanned protocol can be saved, and the setting efficiency of the scanned protocol is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a scanning protocol setting method and device. Background technique [0002] Before performing CT scans on clinical patients, the CT equipment operator needs to set a series of scanning parameters for the CT equipment based on the doctor's medical certificate in order to complete the setting of the scanning protocol. Among them, the scanning protocol determines the data collection method, image reconstruction method, radiation dose and other aspects that need to be used in the scanning process of the patient. [0003] Since there are many correlations and constraints among the parameters in the scanning protocol, different parameter combinations may have a significant impact on the image quality and scanning dose of the final scan. Therefore, CT equipment manufacturers and clinical application personnel will pre-determine a series of scanning protocols based on various...
