摘要:
A radiation imaging apparatus is provided. The radiation imaging apparatus includes a radiation detector including a plurality of detector modules disposed therein, each detector module including a plurality of radiation detecting elements, wherein each of the detector modules includes a temperature sensor. The radiation imaging apparatus further includes an acquiring device configured to acquire temperature characteristic information of sensitivities of the radiation detecting elements from a storing device in which the temperature characteristic information is stored in advance, and a correcting device configured to correct data detected by the radiation detecting elements, based on temperature information acquired by the temperature sensor and the temperature characteristic information acquired by the acquiring device.

The present invention provides always stably sampling a high quality image irrespective of the displacement of a subject, with a simpler arrangement. The image sensor in accordance with the present invention includes a plurality of photodiodes arranged in a two-dimensional array and a plurality of read out gate circuits for reading out the photoelectric conversion charge accumulated in the photoreceptor of each of the photodiodes, in which first and second gate electrodes are provided in the opposing side of an insulator layer for forming respectively first and second potential wells in the vicinity of each of the photoreceptor, charge stored in each photoreceptor for a predetermined period of time is sequentially transferred to the first and second potential wells each at once, a potential barrier is formed for blocking the movement of charge between the photoreceptor and the second potential well by disappearing the first potential well, and charge accumulated in the second potential well is read out in a time division basis.
