    Calculate the effective scanning surface area of a CT scanner's cylindrical chamber to determine the maximum diagnostic coverage area for patient assessment, where the coverage directly impacts readmission risk evaluation accuracy. The scanning surface area should be computed using the chamber's radius and height measurements, excluding the top and bottom circular faces of the cylinder.
