A detector array in a CT system refers to the entire collection of detectors that are used to capture the X-ray data from the patient after the X-rays have passed through the body. These detectors play a crucial role in forming the images produced by the CT scanner, as they convert the incoming X-ray photons into electrical signals, which are then processed to create two-dimensional images.

This array is designed to maximize the efficiency and accuracy of the imaging process by ensuring that a wide range of angles and positions can be captured during each rotation of the CT scanner. The configuration and composition of the detector array can vary depending on the type and model of the CT scanner, but its function remains integral to the system's performance.

The other options do not accurately describe the concept of a detector array. A collection of images produced by the scanner pertains more to the results of the scanning process rather than the mechanics behind image acquisition. The area scanned during a single rotation describes the spatial aspect of the imaging process but does not define the detector array itself. An array of filters used in image processing is related to the post-processing of images, not the initial data acquisition facilitated by the detectors.
