What type of field does the computed tomography (CT) system save the patient's anatomy as raw data?

The correct answer is that the computed tomography (CT) system saves the patient's anatomy as raw data within the scan field-of-view (SFOV). The SFOV encompasses the area from which the CT system collects data during the scanning process. It is specifically defined based on the geometry of the scanner and the area being examined, allowing for the acquisition of relevant anatomy data. The SFOV determines the extent of tissue imaged and ensures that the collected data represent the area of interest accurately.

This concept is vital in CT imaging because it influences the quality of the image and the clarity of anatomical details. The data set obtained within the SFOV will be used in creating cross-sectional images of the patient's anatomy.

The other options relate to different aspects of CT imaging. The display field-of-view (DFOV) refers to the area of the image that is displayed after the scan, which may not include all the data collected within the SFOV. Data saved outside the SFOV would not be relevant for image reconstruction and analysis, as it would not consist of the anatomy being imaged. The scanner gantry represents the physical structure of the scanner itself, which houses the components necessary for scanning, but it does not imply where the data is saved. Understanding these distinctions is
