Abstract
Disclosed is a coded-aperture-based dual particle image fusion apparatus that simultaneously fuses a real-time site image of a radiation source and a reaction image of gamma rays and neutrons to perform nuclide discrimination through the position of radiation, dose per second, and spectrum information, to provide numerical information of dose, and to visualize position information of gamma rays and neutrons through GPS information, whereby it is possible to secure worker safety, and that has a compact size so as to be easily carried, whereby it is possible to create a radiation distribution map based on location movement.
Claims9
A coded-aperture-based dual particle image fusion apparatus comprising:
- an optical camera configured to photograph a site of a radiation source in order to acquire a site image;
- a coded aperture configured to allow radiation emitted from the radiation source to be incident thereupon, a coded pattern being applied to the coded aperture;
- a scintillator array having a structure in which pixels are arranged in an NxN matrix, the scintillator array being configured to generate a scintillation signal for gamma rays and neutrons from the radiation incident through the coded aperture;
- an optical sensor array having a structure in which pixels are arranged in an NxN matrix, the optical sensor array being configured to acquire an electrical signal for the scintillation signal generated through the scintillator array;
- a signal processing unit configured to discriminate between reaction positions of the gamma rays and the neutrons and reaction signals for reaction size based on the electrical signal;
- an image fusion unit configured to record a reaction image of each of the gamma rays and the neutrons based on the reaction signal and to fuse the site image and the reaction image in order to acquire a fused image;
- and
- a display configured to output the fused image.
