Title:
RADIOGRAPHIC SYSTEM
Document Type and Number:
Japanese Patent JP2018099287
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To make it possible that in a radiographic system comprising a radiation projection apparatus, a radiographic apparatus, and a synchronization control unit for sending a synchronization signal to each of these apparatuses, the synchronization between the radiation projection apparatus and the radiographic apparatus is not affection even if the synchronization signal is mixed with noise.SOLUTION: A radiographic system 1 includes a noise detection unit 5 for detecting a noise mixed in the synchronization signal, and a signal correction unit 6 for correcting the synchronization signal according to a detection result of the noise detection unit 5. The noise detection unit 5 compares the pulse width of a pulse of the synchronization signal sent from a synchronization control unit 8 with a preset minimum pulse width T, based on a frame rate f of a dynamic video and a duty ratio D of a pulse of the synchronization signal, and determines a pulse width smaller than the minimum pulse width Tto be a nose.SELECTED DRAWING: Figure 1
