Paper Abstract

A method for determining the Square Wave Response function (SWR) for Computerized Tomographic (CT) systems is described. A 3° segmented acrylic phantom was scanned with water and also air as a second material. The data for each row of pixels was fit to a sine wave by an iterative least square program. The amplitude, phase shift, frequency and "D.C." level of the sine wave were all allowed to vary. The SWR was determined for various modes of the GE 8800 CT/T scanner. Advantages and limitations of the method are discussed.
