    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.

    Abstract: The present invention relates to a method of controlling sensor gain of a positron emission tomography (PET). More specifically, the present invention relates to a method of controlling sensor gain of a positron emission tomography which includes converting radiation detected by a signal conversion unit into an electrical signal; amplifying the converted electrical signal by a pre-amplifying unit; sampling the electrical signal by a digital conversion unit and converting the electrical signal into a digital signal; extracting at least one data from the digital signal by a data obtaining unit and processing signals of the extracted data; and imaging the signal-processed data by an image obtaining unit to obtain a PET image, wherein the amplifying the electrical signal by the pre-amplifying unit further includes a process in which a resistance value is adjusted to control a gain value of the electrical signal. The method of controlling sensor gain of a positron emission tomography may further include supplying constant voltage to the detector by a power supply unit to constantly maintain the performance of the positron emission tomography. The method of controlling sensor gain of a positron emission tomography is able to obtain constant performance and gain value without being affected even if the temperature of the positron emission tomography is changed.
