Problems solved by technology

But this will bring a new problem, that is, on the CT plain scan image, the lumen of the blood vessel is not visible, and it is difficult to distinguish it from the muscle tissue, and it is impossible to determine which coronary artery the detected calcified plaque is located on. Doctors need to order according to experience. Check and identify
[0003] In the prior art, the staff mainly determines which coronary artery the calcification point is located on based on experience, and there is a certain error

Embodiment 1

[0029] figure 1 It is a schematic flowchart of a method for determining the coronary artery branch where the calcified area is located in Embodiment 1 of the present invention. This embodiment can be applied to quickly determine the coronary artery branch where the calcified area is located. The device for determining the branch is executed, and the device can be implemented in the form of software and / or hardware.

[0030] like figure 1 Described, the method of the present embodiment comprises:

[0031] S110. Acquire the image to be processed, and perform registration with the heart standard model to obtain a first pre-processed image, wherein the image to be processed includes a calcification area.

[0032] In order to clearly introduce the technical solution of this embodiment, the part to be scanned is the heart as an example.

[0033] Wherein, the original image obtained after scanning the part to be scanned is used as the image to be processed. The scanned part may b...

Embodiment 2

[0054] Before determining which branch of the coronary artery the calcified area in the image to be processed is located in, it is also necessary to determine the standard model of the heart and the chamber classifier corresponding to each chamber, so as to register the image to be processed based on the standard heart model, A heart model is obtained to determine the target coronary artery to which the calcified region belongs according to the heart model. figure 2 It is a schematic flowchart of a method for determining the coronary artery branch where the calcified area is provided in the second embodiment of the present invention.

[0055] like figure 2 As shown, the method includes:

[0056] S210. Acquire multiple historical heart images as multiple current registration sample images, and mark key information in the current registration samples, where the key information includes actual chamber edges of the heart.

[0057] Wherein, the plurality of historical cardiac i...

Embodiment 3

[0075] As a preferred embodiment of the above embodiment, image 3 It is a schematic flowchart of a method for determining the coronary artery branch where the calcified region is provided by the embodiment of the present invention.

[0076] like image 3 Described, the method of the present embodiment comprises:

[0077] S301. Reading in training data.

[0078] Select a certain amount of training data, optional, thousands or tens of thousands, etc. The training data can be understood as heart scan images.

[0079] It should be noted that in order to obtain the heart model, the size and resolution of the heart image need to be consistent.

[0080] Specifically, a preset number of training sample images are acquired to train the cardiac standard model.

[0081] S302 , marking heart chambers and coronary arteries.

[0082]Before training the data, the left ventricle, right ventricle, left atrium, right atrium, pulmonary artery root, aortic base, etc. structures of the hear...

Abstract

The embodiment of the invention discloses a method and device for determining coronary artery branches where a calcified area is located, a server and a storage medium, and the method comprises the steps: obtaining a to-be-processed image, registering a pre-obtained heart model to the to-be-processed image, and obtaining a first preprocessed image, the to-be-processed image comprising the calcified area; obtaining a heart chamber model corresponding to the to-be-processed image based on the first preprocessed image; and determining a target coronary artery branch where the calcified area is located according to a target chamber where the calcified area is located in the heart chamber model and the probability value of the calcified area located on at least one coronary artery branch to beselected in the target chamber. According to the technical scheme, the technical problem that in the prior art, a worker needs to determine which coronary artery the calcification point is located onaccording to experience, and a certain error exists is solved, and the technical effect of rapidly and accurately determining the target coronary artery to which the calcification point belongs is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of medical technology, and in particular to a method, device, server and storage medium for determining a coronary artery branch where a calcified region is located. Background technique [0002] Coronary artery disease has become the disease with the highest mortality rate in the world. With the development of medical imaging technology, cardiac CT imaging is increasingly used for the detection of coronary artery disease. There are two main types of cardiac CT scans, enhanced scans and non-enhanced scans. Non-enhanced scans are also called plain scans. Enhanced scans require the injection of contrast agents. The blood flow containing contrast agents appears high brightness in CT. This method is mainly used to view the vascular lumen, cardiac chambers, and myocardial perfusion. However, it is not sensitive enough to vascular calcification, because the CT value of the vascular lumen and the ...
