Method, apparatus, device and storage medium for extracting a cardiovisceral vessel from a CTA image

An apparatus for extracting a cardiovisceral vessel from a CTA image, comprising:

• a structure template acquiring unit, configured for performing a corrosion operation and an expansion operation on an image data successively via a preset structural element to obtain a structure template, wherein the image data is a coronary angiography image after a downsampling processing, and the structure template is a structure excluding a pulmonary region;
• a layer-by-layer transformation unit, configured for performing a transformation in layer-by-layer on slice images of the structure template to acquire a first ascending aorta structure in the structure template, and acquiring an aorta center coordinate and an aorta radius in the last layer of slice image of the structure template;
• and
• a synthesizing unit, configured for establishing a binarized spherical structure according to the aorta center coordinate and the aorta radius and synthesizing a second ascending aorta structure by combining the first ascending aorta structure with the structure template and the binarized spherical structure.

A device for extracting a cardiovisceral vessel from a CTA image, comprising:

• a memory, a processor and a computer program that is stored in memory and is executable on the processor, wherein when the computer program is executed by the processor, steps of a method for extracting a cardiovisceral vessel from a CTA image are implemented, wherein the steps of the method comprises:
