Problems solved by technology

[0002] In the current pulmonary angiography operation, the characteristics of the patient's lesions are small in size, uncertain in location, and not fixed in number. This has caused the problem that doctors face is that the pulmonary artery has a large number and complex structure, and the inspection is too difficult.
At present, most of the doctor's surgical plans are based on experience and will perform multiple operations

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0026] Such as figure 1 As shown, the blood vessel sorting method based on pulmonary artery CT images of the present invention sorts the pulmonary vessels that may have problems in a certain order by analyzing the pulmonary artery CT images, and provides reference pulmonary angiographic indicators, including the following steps:

[0027] (1) Import the patient's pulmonary artery CT scan slice image;

[0028] (2) Pulmona...

Abstract

The invention discloses a blood vessel sorting method based on pulmonary artery CT images, comprising: segmenting pulmonary artery CT images to obtain left pulmonary artery vessels and right pulmonary artery vessels; calculating the centerline of pulmonary artery vessels, and obtaining a list of pulmonary artery vessels through the centerline; calculating each The pressure drop of the vessel; reorders the list of vessels based on the pressure drop. The pulmonary arteries are sorted according to the changes in pressure drop, which improves the accuracy of pulmonary angiography and greatly shortens the treatment time.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a blood vessel sorting method based on pulmonary artery CT images, which can be applied to the analysis of pulmonary artery CT images in clinical research. Background technique [0002] In the current pulmonary angiography operation, the characteristics of the patient's lesion are small in size, uncertain in location, and not fixed in number. This has caused the problem faced by doctors that the number of pulmonary arteries is large, the structure is complex, and the examination is too difficult. At present, doctors' surgical plans are mostly based on experience and will perform multiple operations. In this case, patients will face the dual pressure of surgery costs and physical recovery, and some patients who cannot afford it economically will choose to delay treatment or even give up treatment. The present invention thus comes. Contents of the invention [...
