Abstract

A radiographic imaging apparatus includes a radiographic-image detecting unit configured to detect radiation and convert the detected radiation to an image signal; a wireless transmission unit configured to wirelessly transmit the image signal to an external device; and a housing configured to cover the radiographic-image detecting unit and the wireless transmission unit, wherein a first side surface of the housing has a first opening for wireless transmission performed by the wireless transmission unit, and a second side surface of the housing adjoining the first side surface has a second opening for wireless transmission by the wireless transmission unit.

Claims

1. A radiographic imaging apparatus comprising:

a radiographic-image detecting unit configured to detect radiation and convert the detected radiation to an image signal;

a wireless transmission unit configured to wirelessly transmit the image signal to an external device; and

a housing configured to cover the radiographic-image detecting unit and the wireless transmission unit, wherein;

a first side surface of the housing has a first opening except for an edge of the first side surface for wireless transmission to a direction of the first side surface from the wireless transmission unit, and

a second side surface of the housing adjoining the first side surface has a second opening except for an edge of the second side surface for wireless transmission to a direction of the second side surface from the wireless transmission unit.

2. The radiographic imaging apparatus according to claim 1, wherein a first non-conductive member is disposed in the first opening, and a second non-conductive member is disposed in the second opening.

3. The radiographic imaging apparatus according to claim 2, wherein the first non-conductive member and the second non-conductive member have a light blocking effect.

4. The radiographic imaging apparatus according to claim 1, wherein the first non-conductive member and the second non-conductive member are provided as an integrated structure.

5. The radiographic imaging apparatus according to claim 1, wherein the wireless transmission unit is a wireless transmission antenna.

6. The radiographic imaging apparatus according to claim 1, further comprising:

a readout circuit disposed at a first side inside the radiographic imaging apparatus and configured to readout the image signal from the radiographic-image detecting unit,

wherein the radiographic imaging apparatus is shaped as a cuboid, and

wherein the wireless transmission unit is disposed at a second side different from the first side inside the radiographic imaging apparatus.

7. The radiographic imaging apparatus according to claim 1, further comprising:

a shielding plate interposed between the radiographic-image detecting unit and the wireless transmission unit and configured to prevent an influence of noise.

8. The radiographic imaging apparatus according to claim 6, wherein the wireless transmission unit is disposed at the center of the second side.
