Is anything outside the SFOV imaged?

The selected answer indicates that nothing outside the Field of View (SFOV) is imaged during a CT scan. This is accurate because the SFOV is defined specifically as the area that is being captured or visualized by the scanner. The imaging process is designed to focus only on the specified region of interest, and any structures or objects beyond this defined area do not get included in the final images.

This principle is critical in ensuring that the images produced are relevant and useful for diagnostic purposes. It allows medical professionals to concentrate on the area of concern without extraneous information that could complicate interpretation. The SFOV is determined by the parameters set during the scan, and since imaging algorithms are designed to apply only to this specific area, anything located outside of it will not be recorded or visualized at all. As a result, the information collected is precise and tailored to the needs of the diagnostic process.
