Postprocessing of a digital image that combines multiple images into one image is called:

• A. Smoothing
• B. Stitching
• C. Subtraction
• D. Rescaling

Answer: (B)

Combining multiple images into a single seamless image is stitching. In digital postprocessing, stitching takes overlapping individual frames, aligns them so their shared features match, and blends the overlaps to form one larger image with a continuous field of view. This lets you cover more anatomy than any single shot and is useful for wide-area exams. Smoothing reduces noise or blur but doesn’t merge frames. Subtraction creates a difference image between two images, not a composite. Rescaling changes image size or resolution, not how images are combined.
