Heart multi-plane reconstruction method

Abstract

The invention discloses a heart multi-plane reconstruction method. The method includes the following steps of firstly, inputting a three-dimensional image of the heart, and initially positioning the area where the heart is located; secondly, conducting detection to determine the key feature points, in the direction of a long axis, of the heart through a heart position detector according to the area where the heart is located, and obtaining the long axis of a traditional heart viewing angle according to the key feature points; thirdly, continuing detection to determine key feature points, in the direction of a first short axis, of the heart, and obtaining the first short axis of the traditional heart viewing angle according to the key feature points; fourthly, enabling the direction of the long axis and the direction of the first short axis to be orthogonal so as to obtain the direction of a second short axis; fifthly, converting the three-dimensional image of the heart into an image based on the long axis, the first short axis and the second short axis of the traditional heart viewing angle. According to the heart multi-plane reconstruction method, automatic heart multi-plane reconstruction is achieved by detecting the positions of the key feature points of the heart and determining the directions of the long axis and the short axes of the heart, the calculation amount is greatly reduced, and reconstruction time is greatly shortened.

Description

technical field [0001] The invention relates to a medical image reconstruction method, in particular to a heart multi-plane reconstruction method. Background technique [0002] The position of the heart in the thoracic cavity varies greatly among individuals, and standard orthogonal axis planes such as the transverse, coronal, and sagittal planes of the body cannot be used for tomographic imaging. In order to have a unified anatomical description of the heart, the American Heart Association (AHA) unified the cross-sectional anatomical imaging and naming methods of the heart in 2002. In order to make the obtained cardiac tomographic images closer to the standards recommended by the American Heart Association, medical images (including MRI, CT, ultrasound and other modal data) need to be corrected for multi-plane reshaping of the heart. [0003] The existing cardiac multi-plane reconstruction methods are mainly divided into human-computer interaction methods and model matchin...

Problems solved by technology

[0005] It can be seen from the above that most of the existing heart multi-plane reconstruction methods need to register the heart model grid or perform human-computer interaction, which often has the problem of excessive calculation, or requires complex manual operations, which cannot meet the needs of commercial systems.
