RADIATION IMAGING APPARATUS AND RADIATION IMAGING SYSTEM

摘要

A radiation imaging apparatus comprises a read unit reading the electric signal in the radiation detecting elements in a radiation detecting unit comprises the radiation detecting elements converting incident radiation into electric signals arranged two-dimensionally, a control unit controlling the radiation detecting unit with such that a first radiation detecting element group is made senseless state and a second radiation detecting element group is made sensible state, and a signal processing unit performing a subtraction processing such that the electric signal in the radiation detecting elements made senseless state read by the read unit is subtracted from the electric signal in the radiation detecting elements made sensible state read by the read unit according to the state control by the control unit, to reduce conspicuous line noise in an image by a relatively simple configuration.
