Abstract

An image capturing system includes a cassette having a radiation detector, an image memory, and a cassette controller, an image capturing apparatus, a display device, and a host computer. The cassette controller comprises a capacity value transmitter for transmitting a capacity value of the radiation image information to the host computer before transmission process, and an image transmitter for transmitting the radiation image information. The host computer comprises an indicator controller for controlling the display device to display an indicator representing the capacity value received from the cassette as the upper limit, and a bar controller for controlling the display device to display a bar moving toward the indicator and having a length corresponding to the received capacity value of the radiation image information while the radiation image information is being received.

Claims

1. A medical system comprising:

a radiation detecting cassette having;

a casing;

a radiation conversion panel housed in said casing for detecting a radiation that has passed through a subject and converting the detected radiation into radiation image information;

a memory housed in said casing for storing the radiation image information converted by said radiation conversion panel;

a communication unit housed in said casing for transmitting at least said radiation image information to an external device; and

a cassette controller housed in said casing, said medical system further comprising;

a communication sustaining unit housed in said casing of said radiation detecting cassette and adapted to keep said radiation image information transmitted at least during a period of time in which said communication unit is transmitting said radiation image information, and

a display unit adapted to display that said radiation image information is being transmitted from said communication unit.

2. A medical system according to claim 1, wherein said display unit is mounted on a surface of said casing of said radiation detecting cassette.

3. A medical system according to claim 1, further comprising:

an image capturing apparatus adapted to radiate the radiation to said subject; and

a computer adapted to exchange information with said radiation detecting cassette and control said image capturing apparatus,

wherein said display unit is connected to said computer.

4. A medical system according to claim 1, further comprising a cradle adapted to charge a battery housed in said radiation detecting cassette, wherein

said display unit is mounted on a surface of said cradle.

5. A medical system according to claim 1, wherein said display unit comprises a light-emitting device adapted to emit light during said period of time in which said communication unit is transmitting said radiation image information.

6. A medical system according to claim 1, wherein said display unit comprises an indicator representing an upper limit of a capacity value of said radiation image information transmitted by said communication unit, and a bar image, which moves toward said indicator so as to have a length corresponding to the received capacity value of said radiation image information during said period of time in which said communication unit is transmitting said radiation image information.

7. A medical system according to claim 1, further comprising a battery pack housed in said casing,

wherein said communication sustaining unit comprises a lock mechanism for preventing said battery pack from being removed out of said casing at least during said period of time in which said communication unit is transmitting said radiation image information.

8. A medical system according to claim 1, further comprising a connector housed in said casing for connecting to a cable,

wherein said communication sustaining unit comprises a lock mechanism for preventing said cable from being disconnected from said connector at least during said period of time in which said communication unit is transmitting said radiation image information.

9. A medical system according to claim 1, wherein said communication sustaining unit comprises a mechanism for preventing detachment of a device necessary for said communication unit to transmit said radiation image information.

10. A medical system according to claim 9, wherein the device is a battery pack housed in said casing.

11. A medical system according to claim 9, wherein the device is a power cable connected to a connector housed in said casing.

12. A medical system according to claim 9, wherein the device is a communication cable connected to a connector housed in said casing.

13. A radiation detecting cassette having:

a casing;

a radiation conversion panel housed in said casing for detecting a radiation that has passed through a subject and converting the detected radiation into radiation image information;

a memory housed in said casing for storing the radiation image information converted by said radiation conversion panel;

a communication unit housed in said casing for transmitting at least said radiation image information to an external device;

a cassette controller housed in said casing;

a communication sustaining unit housed in said casing adapted to keep said radiation image information transmitted at least during a period of time in which said communication unit is transmitting said radiation image information, and

a display unit mounted on said casing and adapted to display that said radiation image information is being transmitted from said communication unit.

14. A radiation detecting cassette according to claim 13, wherein said display unit comprises a light-emitting device adapted to emit light during said period of time in which said communication unit is transmitting said radiation image information.

15. A radiation detecting cassette according to claim 13, wherein said display unit comprises an indicator representing an upper limit of a capacity value of said radiation image information transmitted by said communication unit, and a bar image, which moves toward said indicator so as to have a length corresponding to the received capacity value of said radiation image information during said period of time in which said communication unit is transmitting said radiation image information.
