Radiation detector comprising fiber optic plates and image sensors, radiation detector manufacturing method, and image processing method

A radiation detector comprising:

• a wiring board;
• a first image sensor and a second image sensor adjacent to each other on the wiring board;
• a first fiber optic plate comprising a plurality of optical fibers and a second fiber optic plate comprising a plurality of optical fibers adjacent to each other on the first image sensor and the second image sensor;
• and
• a scintillator layer provided on the first fiber optic plate and the second fiber optic plate,
• wherein the first fiber optic plate has a first light entering surface, a first light exiting surface, and a first side surface connecting the first light entering surface and the first light exiting surface, and is capable of guiding light between a first light entering region of the first light entering surface and a first light exiting region of the first light exiting surface,
• wherein the second fiber optic plate has a second light entering surface, a second light exiting surface, and a second side surface connecting the second light entering surface and the second light exiting surface, and is capable of guiding light between a second light entering region of the second light entering surface and a second light exiting region of the second light exiting surface,
• wherein one side of the first light entering region on a side of the second light entering region and one side of the second light entering region on a side of the first light entering region are in contact with each other,
• wherein the first light exiting region is positioned on a first light receiving region of the first image sensor,
• wherein the second light exiting region is positioned on a second light receiving region of the second image sensor,
• wherein one side surface of the first side surface on the second fiber optic plate and one side surface of the second side surface on the first fiber optic plate exhibit shapes along each other and are in contact with each other,
• wherein the first light entering surface and the first light exiting surface are in a positional relationship of facing each other, and the second light entering surface and the second light exiting surface are in a positional relationship of facing each other, and
• wherein a direction along which each of the plurality of optical fibers constituting the first fiber optic plate extends and a direction along which each of the plurality of optical fibers constituting the second fiber optic plate extends are in a positional relationship of intersecting each other.
