Abstract

A cassette device includes a radiation detecting cassette having a radiation detector therein for detecting radiation having passed through a subject and converting the detected radiation into radiation image information, a transmission and reception controller connected to the radiation detector for transmitting the radiation image information to an image processor by way of wireless communications, and a cassette storage bag for storing the radiation detecting cassette therein. The cassette storage bag includes an antenna incorporated therein for transmitting the radiation image information from the transmission and reception controller to the image processor by way of wireless communications. The transmission and reception controller and the antenna are capable of being electrically connected to each other through detachable connectors.

Claims

1. A cassette device comprising:

a radiation detecting cassette having a radiation conversion panel for detecting radiation that has passed through a subject and converting the detected radiation into radiation image information, and a transmitting unit connected to said radiation conversion panel for transmitting said radiation image information to an image processor by way of wireless communications; and

a cassette storage bag for storing said radiation detecting cassette,

wherein said cassette storage bag includes an antenna for transmitting said radiation image information from said transmitting unit to said image processor by way of wireless communications, and

wherein said transmitting unit and said antenna are electrically connectable to each other through detachable couplings.

2. A cassette device according to claim 1, wherein said couplings comprise connectors, respectively, for engaging respective distal ends of a communication wire extending from said transmitting unit and a communication wire extending from said antenna.

3. A cassette device according to claim 1, wherein said couplings comprise magnetic couplings, respectively, mounted on respective distal ends of a communication wire extending from said transmitting unit and a communication wire extending from said antenna, at least one of said magnetic couplings being made of a magnetic material that is magnetically attracted to the other of the magnetic couplings, for thereby electrically connecting said communication wires to each other.

4. A cassette device according to claim 1, wherein said antenna comprises a printed antenna, which is printed on said cassette storage bag.

5. A cassette device according to claim 1, wherein said antenna is disposed on a rear wall of said cassette storage bag opposite to a surface of said radiation detecting cassette that is irradiated with said radiation while said radiation detecting cassette is stored in said cassette storage bag.

6. A cassette storage bag for storing a radiation detecting cassette having a radiation conversion panel for detecting radiation that has passed through a subject and converting the detected radiation into radiation image information, and a transmitting unit connected to said radiation conversion panel for transmitting said radiation image information to an image processor by way of wireless communications, said cassette storage bag comprising:

an antenna for transmitting said radiation image information from said transmitting unit to said image processor by way of wireless communications, said antenna being electrically connectable to said transmitting unit by a detachable coupling.

7. A cassette storage bag according to claim 6, wherein said coupling comprises a connector for engaging a communication wire that extends from said transmitting unit.

8. A cassette storage bag according to claim 6, wherein said coupling comprises a magnetic connector for magnetically attracting and connecting to a communication wire that extends from said transmitting unit.

9. A cassette storage bag according to claim 6, wherein said antenna comprises a printed antenna, which is printed on said cassette storage bag.

10. A cassette storage bag according to claim 6, wherein said antenna is disposed on a rear wall of said cassette storage bag opposite to a surface of said radiation detecting cassette that is irradiated with said radiation while said radiation detecting cassette is stored in said cassette storage bag.

11. A cassette storage bag according to claim 10, wherein said cassette storage bag bears a marking thereon, which indicates said surface of said radiation detecting cassette that is irradiated with said radiation, or which indicates said rear wall of said cassette storage bag.
