ABSTRACT
This paper is to approach a simple method for Wiener spectrum measurement in different medial imaging systems. The program written in VC++6.0 can be used to obtain the density datum as discrete signals by scanning films on AGFA DUOSCAN T2000XL scanner, then WS values can be calculated by using fast Fourier transform. The method is applied to different x-ray photographs and the WS values are consistent with the known datum from MD-100 micro-densimeter. The method can make automatic data collection and procedural calculation, showing the characteristics of its simplicity and high speed.
