Abstract

Provided is a radiography apparatus capable of changing the shape and size at an imaging site. A radiography apparatus ( 1 ) includes a scintillator ( 12 ), and a substrate ( 11 ) that is laminated on the scintillator ( 12 ) and has a plurality of photoelectric conversion elements ( 17 ) converting light emitted from the scintillator ( 12 ) into electric charges, in which a laminate including the scintillator ( 12 ) and the substrate ( 11 ) is partitioned into a plurality of blocks ( 10 A) to ( 10 I), and the blocks are separable from each other.

Claims (26)

1. A radiography apparatus comprising:

a plurality of blocks, each of the plurality of blocks comprising:

a scintillator having flexibility;

a substrate which is a flexible substrate having flexibility, and on which a plurality of photoelectric conversion elements converting light emitted from the scintillator into electric charges are formed; and

a laminate in which the scintillator and the substrate are laminated,

wherein each block of the plurality of blocks is separable from and re-connectable to each other; and

the radiography apparatus further comprises:

a drive circuit formed separately from each of the plurality of blocks and connected to a first subset of blocks including one or more blocks aligned along a first direction; and

a signal processing circuit formed separately from each of the plurality of blocks and connected to a second subset of blocks including one or more blocks aligned along a second direction perpendicular to the first direction

wherein the drive circuit and the signal processing circuit are disposed at the second direction with respect to the aligned one or more blocks.

2. The radiography apparatus according to claim 1 , further comprising:

a plurality of switching elements provided on the substrate and provided corresponding to the plurality of photoelectric conversion elements;

a plurality of gate lines provided on the substrate and transmitting drive signals for driving each of the plurality of switching elements;

a plurality of signal lines provided on the substrate and transmitting electric signals based on the electric charges generated by the plurality of photoelectric conversion elements;

wherein a plurality of drive circuits are connected to a part of different gate lines among the plurality of gate lines and outputting the drive signals, respectively; and

the plurality of signal processing circuits are connected to a part of different signal lines among the plurality of signal lines and processing the electric signals, respectively,

wherein in each of the plurality of blocks, each of the gate lines included in the block is connected to one of the plurality of drive circuits, and each of the signal lines included in the block is connected to one of the plurality of signal processing circuits.

3. The radiography apparatus according to claim 2 ,

wherein the plurality of drive circuits and the plurality of signal processing circuits are provided along one side of the laminate.

4. The radiography apparatus according to claim 2 ,

wherein the plurality of drive circuits and the plurality of signal processing circuits are provided along two sides of the laminate opposite to each other.

5. The radiography apparatus according to claim 4 ,

wherein the plurality of drive circuits are electrically connected to each other, and

the plurality of signal processing circuits are electrically connected to each other.

6. The radiography apparatus of claim 1 wherein the first subset of the plurality of blocks are located at a periphery of the plurality of blocks and arranged in the first direction, and wherein the second subset of the plurality of blocks are located a periphery of the plurality of blocks and arranged in the second direction.

7. The radiography apparatus of claim 1 wherein the drive circuit and the signal processing circuit are disposed at one side of the second direction with respect to the aligned one or more blocks.
