Abstract

A cassette allows radiation image information stored therein to be used immediately after an X-ray radiation image is captured in a patient'"'"'s room, and a mobile X-ray image capturing apparatus incorporates such a cassette. The mobile X-ray image capturing apparatus has a cradle serving as a mount for receiving the cassette which has a radiation detector. The mobile X-ray image capturing apparatus captures a radiation image of the patient (subject) in the patient'"'"'s room. The cassette serves as a mobile station. While the cassette (mobile X-ray image capturing apparatus) is moving, the radiation image information stored in the cassette is transmitted to a server via a transmitting and receiving terminal, a mobile hospital communication network, and a hospital LAN.

Claims

1. A cassette comprising:

a radiation detector for detecting a radiation that has passed through a subject, and converting the detected radiation into radiation image information;

an image memory for storing the converted radiation image information therein;

a transmitting and receiving terminal; and

a controller for controlling said radiation detector, said image memory, and said transmitting and receiving terminal;

wherein said transmitting and receiving terminal serves as a mobile station and communicates with a radiation image information collecting facility through a mobile communication network; and

when said controller detects that said radiation image information is stored in said image memory, said controller transmits said radiation image information stored in said image memory to said radiation image information collecting facility via said transmitting and receiving terminal and said mobile communication network, while the cassette is moving.

2. A cassette according to claim 1, wherein said mobile communication network includes a plurality of base stations having partially overlapping communication ranges, and said transmitting and receiving terminal comprises a mobile terminal capable of sending and receiving signals by way of wireless communications.

3. A mobile X-ray image capturing apparatus a cassette comprising:

a radiation detector for detecting a radiation that has passed through a subject, and converting the detected radiation into radiation image information;

an image memory for storing the converted radiation image information therein;

a transmitting and receiving terminal; and

a controller for controlling said radiation detector, said image memory, and said transmitting and receiving terminal;

wherein said transmitting and receiving terminal serves as a mobile station and communicates with a radiation image information collecting facility through a mobile communication network; and

when said controller detects that said radiation image information is stored in said image memory, said controller transmits said radiation image information stored in said image memory to said radiation image information collecting facility via said transmitting and receiving terminal and said mobile communication network, while the cassette is moving,

wherein said mobile communication network includes a plurality of base stations having partially overlapping communication ranges, and said transmitting and receiving terminal comprises a mobile terminal capable of sending and receiving signals by way of wireless communications; and

a mount for receiving removably the cassette therein and supplying electric power to said cassette.

4. A mobile X-ray image capturing apparatus a cassette comprising:

a radiation detector for detecting a radiation that has passed through a subject, and converting the detected radiation into radiation image information;

an image memory for storing the converted radiation image information therein;

a transmitting and receiving terminal; and

a controller for controlling said radiation detector, said image memory, and said transmitting and receiving terminal;

wherein said transmitting and receiving terminal serves as a mobile station and communicates with a radiation image information collecting facility through a mobile communication network; and

when said controller detects that said radiation image information is stored in said image memory, said controller transmits said radiation image information stored in said image memory to said radiation image information collecting facility via said transmitting and receiving terminal and said mobile communication network, while the cassette is moving, and

a mount for receiving removably the cassette therein and supplying electric power to said cassette.

5. A mobile X-ray image capturing apparatus for capturing a radiation image of a subject at a room where an image is to be captured, comprising:

a radiation source for applying a radiation to the subject;

a mount for receiving therein a cassette having a radiation detector for detecting the applied radiation that has passed through the subject, converting the detected radiation into radiation image information and storing the radiation image information;

an image memory;

a transmitting and receiving terminal; and

a controller for controlling said radiation source, said mount, said image memory, and said transmitting and receiving terminal;

wherein said transmitting and receiving terminal serves as a mobile station and communicates with a radiation image information collecting facility through a mobile communication network; and

when said controller detects that said radiation image information is stored in said cassette mounted in said mount, said controller transfers said radiation image information from said cassette via said mount to said image memory for storing the radiation image information therein; and

while said mobile X-ray image capturing apparatus is moving, said radiation image information stored in said image memory is transmitted to said radiation image information collecting facility via said transmitting and receiving terminal and said mobile communication network.

6. A mobile X-ray image capturing apparatus according to claim 5, further comprising:

an exit detecting mechanism for detecting that said mobile X-ray image capturing apparatus has moved out of said room;

wherein said controller starts transmitting said radiation image information to said radiation image information collecting facility when said exit detecting mechanism detects that said mobile X-ray image capturing apparatus has moved out of said room.

7. A mobile X-ray image capturing apparatus according to claim 5, wherein said mobile communication network includes a plurality of base stations having partially overlapping communication ranges, and said transmitting and receiving terminal comprises an existing mobile terminal mounted in said mobile X-ray image capturing apparatus and capable of sending and receiving signals by way of wireless communications.

8. A mobile X-ray image capturing apparatus according to claim 5, wherein said room comprises a room other than an X-ray image capturing room, including an operating room, a patient'"'"'s room, a diagnosis and treatment room, and a home care room.
