Paper Abstract

The most generally used method to determine the MTF of x-ray image intensifiers is through the use of a test object which impresses on the image intensifier a square wave input signal. These devices are usually fabricated from lead sheet by cutting a series of slits of width w separated by an equal width of lead. Different spatial frequencies are obtained by making a series of objects of different slit and separation widths. The output signal resulting from these test objects is the intensifier's response to a square wave. To obtain the MTF, this response is converted mathematically to that which would have resulted from a sinusoidal input signal (1).
