specific Embodiment approach

[0110] Further, the embodiment of the present application provides a specific implementation method of determining the left brain side or the right brain side in the CTA source image as the target side according to the CT value of each MCA blood supply area in the CTA source image, including:

[0111] According to the CT value of each MCA blood supply area in the CTA source image, calculate the first CT mean value of all MCA blood supply areas located on the left brain side and the second CT mean value of all MCA blood supply areas located on the right brain side in the CTA source image;

[0112] The side corresponding to the smaller value of the first CT mean value and the second CT mean value is determined as the target side.

[0113] Using the CT value of each MCA blood supply area in the CTA source image, calculate the first CT mean value of all MCA blood supply areas belonging to the left brain side in the CTA source image, and the first CT mean value of all MCA blood supp...

Abstract

The embodiment of the invention discloses a CT angiography CTA source image processing method, device and equipment, and the method comprises the steps: extracting a brain parenchyma region from a CTA source image, obtaining a brain parenchyma CTA source image, inputting the brain parenchyma CTA source image and a template image corresponding to the CTA source image into a registration model generated through preset training, and obtaining a target deformation field; based on the obtained target deformation field, deforming the MCA brain atlas image corresponding to the template image to obtain an MCA brain atlas image corresponding to the brain parenchyma CTA source image; and obtaining a division result of each MCA blood supply area in the brain parenchyma CTA source image through an MCA brain map image corresponding to the brain parenchyma CTA source image obtained through the target deformation field. According to the MCA brain atlas image corresponding to the brain parenchyma CTA source image obtained based on the target deformation field, the MCA blood supply area in the brain parenchyma CTA source image can be accurately divided.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a method, device and equipment for processing CTA source images. Background technique [0002] A CTA (CT angiography, CT angiography) source image is an image obtained after a CT scan is performed when a contrast agent is injected into a human blood vessel. In the CTA source image, the vascular development is more obvious, which can clearly display the arteries and main branches, and can help doctors understand the blood supply of patients. [0003] The CTA source image can be used to judge the blood supply of multiple blood supply regions of the MCA (Middle Cerebral Artery, middle cerebral artery). At present, the blood supply area of ​​MCA in CTA source images needs to be divided by manual experience, the labor cost is high and the lack of consistency makes it difficult to accurately determine the blood supply of MCA based on CTA source images.
