Problems solved by technology

This method cannot compensate for the displacement caused by the patient's movement or breathing, so there is the problem of inaccurate ROI, which leads to the inability to determine the optimal scanning time of the target vessel and obtain a clearly developed scan image of the target vessel

Embodiment 1

[0034] figure 1 It is a flow chart of an image scanning method provided by Embodiment 1 of the present invention. The technical solution of this embodiment is applicable to the scene of automatically determining the ROI of a target part. For example, after the contrast medium is injected into the target site and before the official scan is performed, the ROI of the target site is determined, so as to determine the appropriate scanning time based on the CT value in the ROI. The method can be executed by an image scanning device, and the device can be realized by software and / or hardware.

[0035] Such as figure 1 As shown, the method specifically includes the following steps:

[0036] Step 110, acquiring the first slice image of the target part at the first moment.

[0037] Specifically, in enhanced scans, such as CT angiography scans, contrast agents will be injected. In order to start scanning at the best time to obtain clear images of blood vessels, after the injection of...

Embodiment 2

[0054] image 3 It is a flow chart of an image scanning method provided by Embodiment 2 of the present invention. On the basis of the above embodiments, this embodiment adds a step of adjusting the position of interest in the region of interest, aiming to further improve The accuracy of the region of interest, especially for the situation that the patient moves or breathing interferes during the scanning process, by adjusting the point of interest in the region of interest can compensate for the patient’s movement during the scanning process The interference caused by movement or breathing makes the region of interest more accurate, the CT value monitoring based on the region of interest is more accurate, and the determined scanning time is more ideal. The explanations of terms that are the same as or corresponding to those in the foregoing embodiments are not repeated here.

Embodiment 3

[0079] Figure 7 It is a flow chart of an image scanning method provided by Embodiment 3 of the present invention. On the basis of the foregoing embodiments, this embodiment describes the image scanning method by taking the target site as an example of the pulmonary artery. The explanations of terms that are the same as or corresponding to those in the foregoing embodiments are not repeated here.

[0080] see Figure 7 The image scanning method provided in this embodiment specifically includes the following steps:

[0081] Step 710, acquiring the first slice image of the pulmonary artery at the first moment.

[0082] Step 720: Input the first slice image into a preset neural network model matched with the pulmonary artery to obtain an output result.

[0083] Wherein, the preset neural network model matched with the pulmonary artery includes a neural network main body, a segmentation network branch and a point positioning network branch; wherein, the segmentation network bra...

Abstract

The embodiment of the invention discloses an image scanning method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a first slice layer image of a target part at a first moment; inputting the first slice layer image into a preset neural network model to obtain an output result; determining a region of interest of the target part according to the output result, wherein when the CT value in the region of interest reaches a CT threshold value, the scanning operation on the target part is triggered. Through the technical scheme of the embodiment ofthe invention, the purpose of automatically determining the ROI of the target part is achieved, and the ROI determination precision and efficiency are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of computed tomography, and in particular, to an image scanning method, device, electronic equipment, and storage medium. Background technique [0002] In enhanced scans, such as CT angiography scans, contrast agents are quickly injected into the patient's veins, and CT scans are performed on the target blood vessels at the moment when the contrast agent concentration in the target blood vessels is optimal according to the blood circulation status of each patient. In order to achieve the purpose of enhancing the target blood vessel and obtaining a clearly developed scanning image of the target blood vessel. [0003] Specifically, first scan a specific part of the patient (such as the chest cavity) to obtain a localization phase, and select a localization slice position based on the scanned localization phase, set an ROI (region of interest, region of interest) at the localization slice ...
