| titleOfInvention | Detector modules for position emission tomography and the position emission tomography using the detector module |
| abstract | The present invention relates to a detector module for a positron emission tomography apparatus, and more particularly, to a detector module for detecting a gamma ray using an annular detection ring formed by arranging a plurality of detectors in a radial direction, A plurality of scintillator crystal cells each having a polygonal columnar shape; and a plurality of scintillator crystal cells each having a polygonal columnar shape, each of the scintillation crystals having a trapezoidal shape on the side thereof and a first reflective film formed on at least one side of the side of the scintillation crystal, And a second reflective film formed on at least one side of the side surface of the crystal cell, wherein the plurality of scintillation crystal cells are arranged on the upper surface of the scintillator crystal so that the side surfaces of the plurality of scintillation crystal cells contact the side surfaces of the adjacent scintillation crystal cells, A second scintillator characterized in that at least one second reflective film is located, A photoelectric conversion unit connected to the plurality of scintillation crystal cells and the scintillation crystals to convert the scintillation signals generated by the plurality of scintillation crystal cells into electrical signals and outputting the electrical signals; The first scintillator is formed so that the trapezoidal side surfaces thereof are brought into contact with each other to form a ring-shaped detection ring. In addition, the present invention relates to a positron emission tomography apparatus using a detector module for positron emission tomography, and more particularly, to an apparatus and method for detecting positron emission tomography in which a detector module according to any one of claims 1 to 10 is provided with an annular detection And a display unit for displaying a video signal output from the signal processing unit, and a signal processing unit for receiving the data from the detection circuit unit and analyzing the generation position of the gamma ray through a predetermined analysis algorithm, do. The present invention has a trapezoidal shape so that the parts to be coupled between the detector modules can be tightly coupled to each other, thereby eliminating the space between the detector modules to prevent detachment of the gamma rays to the outside, thereby enhancing the detection efficiency . In addition, the present invention relates to a method of combining a rectangular array of scintillation crystals in a trapezoidal-shaped scintillation crystal to form two different types of scintillation crystals, and then performing parallax error parallax error can be compensated. That is, the present invention can improve spatial resolution. |
