Which component reviews raw data and performs major image processing?

The array processor is crucial in the CT imaging process, as it is specifically designed to handle the raw data obtained from the detectors. Its main function is to execute complex mathematical computations that are essential for transforming this raw data into a usable image. This involves performing dense image processing tasks such as filtering, convolution, and back-projection, which are vital for reconstructing a clear and accurate representation of the scanned anatomy.

While other components, like the reconstruction algorithm, also play roles in image processing, it is the array processor that directly manages the heavy computational load necessary for processing the extensive data resulting from the CT scans. This specialized hardware is optimized for the speed and efficiency needed for real-time image reconstruction, making it an integral part of the CT system.

In summary, recognizing the array processor's unique role helps clarify why it is the correct answer. Its dedicated purpose in reviewing and processing raw data distinctly sets it apart in the context of CT imaging.
