发明名称 RADIATION IMAGE PHOTOGRAPHING DEVICE
摘要 <p>PROBLEM TO BE SOLVED: To fulfill both of anti-shock capability and image quality of a radiation image photographing device. SOLUTION: In between the inner wall of radiation incidence side of a box and a detection panel, a buffer material is arranged. By the characteristic of the buffer shown with a solid line, the effect of bubbling image probabilistically appears around a certain peak in frequency zone F1 to F2 in spacial distribution for X-ray. By raising the frequency zone F1 to F2 to higher zone than the Nyquist frequency Fs, a structural image by the bubbling as a visible image disappears and so it does not give a strong sense of incongruity. The Nyquist frequency Fs is expressed by Fs=1/2p, where p is the image pitch of sensor.</p>
