How do I create a 24-bit RGB color image from a grayscale image?
You can create a color image from 2 or 3 grayscale images (both 8-bit or 16-bit) using the Image/Image Fusion/Color Fusion function. Each grayscale image is used as one color component, therefore, 3 images will make the red, green, and blue components to form a RGB image. Some users have created color images by combining CT and MRI images. You can use Image/Registration to register the images if they are in different orientation or scale.
