摘要
A method and a circuit are provided for processing pulses, caused by a radioactive source and produced by an imaging radiation detector, by applying the technique of weighted acquisition for forming an image. An image weight function is formed corresponding to the source radiation, said function being dependent on the energy of said pulses in consideration of both the energy dependent signal-to-noise ratios of said pulses and the energy dependent modulation transfer functions of said pulses. Thereby a weighting pulse is obtained for each of said pulses, the particular value of said weighting pulse determined by the observed energy of said pulse. Said weighting pulses are then accumulated as said image.
