    Abstract: PURPOSE: A method for detecting the arrival time of a gamma ray pulse signal in a pet detector is provided to detect the arrival time of a gamma ray pulse signal using a cross point, thereby increasing temporal resolution. CONSTITUTION: An analog-digital converter detects the initial rising line of a voltage value of a digital signal about a gamma ray pulse signal(S610). The analog-digital converter detects a reference line by statistically processing a digital signal(S620). The analog-digital converter calculates the cross point between the initial rising line and the reference line(S630). The analog-digital converter detects the arrival time of the analog-digital converter by using the cross point(S640). The analog-digital converter amplifies a digital signal of the gamma ray pulse signal.
