MRI of the Dicom Image Orientation Algorithm

Objective: Based on the direction cosine vector of the first row and first column of DICOM images,calculate the image orientation information.Methods: The first row and the first column of the direction cosines do cross product operation to obtain the image plane of the normal direction cosine,further analysis by the image orientation information.Results: Establishment of VC++ project,read DICOM image orientation cosine data elements,qualitative analysis of image in three-dimensional coordinates of the image orientation information.Conclusions: Programming of the DICOM medical image orientation calculation,the medical diagnostic imaging and three-dimensional reconstruction of the direction of rotation of the positioning is of great significance.
