Method for measuring diameters of tangent plane of aortic arch by utilizing CT (computed tomography) scanning and 3D post-processing image software

The invention provides a method for measuring diameters of a tangent plane of an aortic arch by utilizing CT (computed tomography) scanning and 3D post-processing image software. By the method, the diameters of the tangent plane of the aortic arch can be accurately measured on the image by utilizing CT scanning and 3D post-processing software. The method has the following technical effects: the diameters of the tangent plane of the aortic arch can be simply and accurately measured by carrying out overall adjustment on the cross section, the coronal plane and the sagittal plane of the aortic arch by utilizing CT scanning and the CT post-processing 3D procedure; and compared with the traditional measurement methods depending on personal experiences, the method provided by the invention is more accurate.
