What is stitching in a CBCT?

• A. Allows acquisition of a larger field of view from a small detector
• B. Requires multiple separate small field of view acquisitions that are superimposed/fused together
• C. Can increase vertical/horizontal field of view
• D. Results in increased patient dose

Answer: (A)

Stitching in CBCT is the process of creating a larger field of view by combining data from multiple scans captured with a smaller detector. You image adjacent regions, then software aligns and fuses the partial images into one seamless, wider view. This lets you visualize more anatomy without needing a single large-detector scan. While it often involves more than one acquisition, the key idea is expanding the FOV from a small detector. Dose implications depend on how many scans are performed and the technique used.
