ABSTRACT:
A signal detecting method and apparatus capable of performing rapid signal reading with the resultant image signal of improved signal-to-noise ratio, in which a charge signal outputted from a radiation image detector is integrated by an integral amplifier, and the integrated electrical signal is passed through a low pass filter to detect it as an image signal. The transient response time of the low pass filter is reduced and a sufficient integration time is secured by altering the time constant of the low pass filter by the time constant altering means such that the time constant during the time period between resetting of the integral amplifier and initiation of the next integration is set smaller than that during the time period between the initiation of the inputting of the integrated electrical signal to the low pass filter and holding of the filtered electrical signal.
