Abstract: An indoor live ammunition shooting range facility system includes a ventilation facility installed in an indoor live ammunition shooting range, and configured to ventilate air of the indoor live ammunition shooting range; a targeting device facility installed in the indoor live ammunition shooting range, and configured to provide a shooting target; a bulletproof facility installed to protect components exposed to an inside of the indoor live ammunition shooting range among components configuring the ventilation facility and the target device facility and to protect a wall surface of the indoor live ammunition shooting range; a bullet head recovery facility installed on a side opposite to a shooting position, and configured to recover a bullet head; and a control facility installed in the indoor live ammunition shooting range, and configured to control the ventilation facility, the target device facility and the bullet head recovery facility.

Abstract: The present invention provides a bullet collecting box which is installed with a plurality of rubber plates in the bullet collecting box having a rectangular parallelepiped shape and filled with rubber powder filling materials having a particle size of 0.1 to 3 mm therein, thereby collecting the bullets fired in the indoor shooting range without damage, and a bullet collecting system which can be used by installing the bullet collecting box in the indoor shooting range. Also, the present invention provides a bullet collecting system for preventing occurrence of lead fume in the indoor shooting range, in which the beaten zone of the indoor shooting range is newly improved from an existing system of using an iron plate to a system of using powder filling materials, thereby preventing the leakage of lead fume, and contributing to an early normalization of the shooting range and a creative national defense.

Abstract: Provided is an apparatus and method for calculating a correction factor, the apparatus including: a counter configured to acquire first data indicating a counted value of a first radiation source according to an activity and an energy window width, and to acquire second data indicating a coincidence value of a second radiation source according to an activity and an energy window width; and a calculator configured to calculate a correction factor for correcting a difference of the coincidence value of the second radiation source having occurred in response to a single gamma photon emission of the first radiation source, based on the first data and the second data.

Abstract: An apparatus and method for determining an optimal energy window for optimal positron emission tomography (PET) is disclosed. An optimal energy window determining apparatus may include a data corrector configured to correct data measured from an image quality phantom, an image quality measurer configured to measure an image quality for the corrected data, and an optimal energy window determiner configured to determine the optimal energy window based on the measured image quality. The data corrector may correct the measured data based on a difference between sensitivities measured using different radiopharmaceuticals in at least one energy window.
