    Abstract: PURPOSE: A gamma-ray detector using a multiple scintillation crystal and a positron emission tomography using the same are provided to improve spatial resolution by checking detailed gamma-ray position information. CONSTITUTION: An optical sensor(110) changes a flashing light signal of a multiple scintillation crystal(100) into an electrical signal. An amplifier(120) easily amplifies an output signal of the optical sensor. An A-D converter(130) checks reaction energy, reaction time, and a reaction site by changing an output signal of the amplifier into a digital signal. A location information determination unit(140) checks each flashing light signal waveform for each multiple scintillation crystal by processing the digital signal with the A-D converter. The location information determination unit checks location information of entered gamma-rays.

    Abstract: PURPOSE: A detector with an inserted light guide capable of easily determining a reaction depth and a PET(Positron Emission Tomography) using the same are provided to easily determine a reaction depth by inserting a light guide between scintillation crystal layers. CONSTITUTION: A reaction site determination PET detector with an inserted light guide is composed of a first scintillation crystal(100), a light guide(110), a second scintillation crystal(120), and an optical sensor(130). A block type light guide is inserted between the first scintillation crystal and the second scintillation crystal. The first scintillation crystal and the second scintillation crystal change radiation into a scintillation light signal by detecting desired radiation. The second scintillation crystal corresponds to a scintillation crystal close to a light source emitting the radiation. The light guide is inserted between each flash scintillation layer to distribute an output scintillation signal to a lower layer as much as is desired. An optical sensor changes the output scintillation signal of the first scintillation crystal and the second scintillation crystal into an electrical signal.

    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.
