ABSTRACT:
A method for transforming radiological image data from a digital receiver obtains digital image data values from the digital receiver and compensates for exposure response differences between a screen film system and the digital receiver. Modulation transfer function differences between the screen film system and the digital receiver are compensated and noise content at frequencies approaching the Nyquist frequency for the digital receiver is suppressed.
