How do I compare a pair of CT/MRI images using 3D-DOCTOR?
3D-DOCTOR provides many different ways to compare 2 or more 3D images (CT, MRI, or microscopy), including image registration, image color fusion, image fusion by arithmetic combination, 3D model combination, and object boundary combination. The following explains each type of comparison and their benefits: • Image Registration: If 2 or more images are in a different orientation and size, you can define 4 or more control points in 3D-DOCTOR and register them against a base image. When images are properly registered, you can compare them using image fusion and other functions. • Image Color Fusion: For 2 or 3 images, use Image/Color Fusion to create a RGB true color image, where each image is used as a color component in the final RGB color image. Differences between images will be shown clearly in the color space as the combined colors. • Image Fusion Using Arithmetic Algorithms: This function combines two 3D images to create a new fusion image using one of the following operators: Add,
