Abstract:
1. An array type X-ray detection apparatus comprising: a plurality of X-ray dose detection devices arranged in a two-dimensional array; reading means of reading from said plurality of X-ray dose detection devices; and potential controlling means of controlling a reference potential to protect said plurality of X-ray dose detection devices and/or said reading means, wherein said plurality of X-ray dose detection devices comprises: charge converting means of converting incident X-rays to charge; charge storing means of storing said charge; charge transferring means of transferring the charge stored in said charge storing means to said reading means; and output limiting means of practically limiting the output potential produced by the charge stored in said charge storing means to said reference potential or below, wherein said output limiting means comprises a PN junction diode, where one end of said PN junction diode is connected to said potential controlling means such that a potential of said one end is controlled to be said reference potential.
