METHOD AND SYSTEM TO CALCULATE THE POINT SPREAD FUNCTION OF A DIGITAL IMAGE DETECTOR SYSTEM BASED ON A MTF MODULATED QUANTUM-NOISE MEASUREMENT

摘要

This invention is related to a method to measure and calculate a point spread function PSF of an image detector system based on the analysis of quantum noise that is present in generic image acquisition data, and that is modulated by the transfer function of the digital imaging system. The method allows the calculation of the sharpness of a system without the need for image phantom recordings.
