Radiation apparatus and radiation signal processing method using bipolar time-over-threshold method

摘要

A radiation apparatus and a radiation signal processing method are provided. To elaborate, the apparatus includes an input unit including a radiation detector; an amplification unit configured to amplify a signal input through the radiation detector; a bipolar signal generation unit configured to generate a bipolar signal by converting the amplified signal; and a comparison unit configured to output a digital signal on the basis of comparison results of the bipolar signal with a preset first threshold value and a preset second threshold value. Herein, the comparison unit includes a first comparator configured to output a digital pulse in an interval where the bipolar signal is larger than the first threshold value and a second comparator configured to output a digital pulse in an interval where the bipolar signal is smaller than the second threshold value.
