Abstract
An automated method has been developed to test the performance of the Somatom-2 CT-scanner. The approach is based on the utilization of the three-section phantom supplied with the device by Siemens. The phantom contains rectangular blocks, a water bath and aluminum strips. Using the blocks, the edge response function, the line spread function and the modulation transfer function are computed. From the water bath section uniformity and noise are assessed: the image is divided into 80 subdivisions organized into four bands, four quadrants and two hemispheres, and the mean and standard deviation are computed for each. The same water bath image is also used for the computation of the noise power spectrum. The computer programs are being converted to facilitate on-line applications.
