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 comprising 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;

an image capturing apparatus for radiating the radiation to said subject;

a host computer for exchanging information with said radiation detecting cassette and controlling said image capturing apparatus; and

a display device for displaying information from said host computer;

wherein said cassette controller comprises a capacity value transmitter for transmitting a capacity value of said radiation image information to said host computer before said radiation image information is transmitted, and an image information transmitter for transmitting said radiation image information; and

said host computer comprises an indicator controller for controlling said display device to display an indicator, which represents said capacity value received from said radiation detecting cassette as an upper limit, and a bar image controller for controlling said display device to display a bar image, which moves toward the displayed indicator so as to have a length corresponding to the received capacity value of said radiation image information during a period of time in which said radiation image information is being received.

2. A medical system according to claim 1, wherein said radiation detecting cassette comprises a communication sustaining unit housed in said casing for keeping said radiation image information transmitted at least during a period of time in which said communication unit is transmitting said radiation image information.

3. A medical system according to claim 2, wherein said radiation detecting cassette comprises 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.

4. A medical system according to claim 2, wherein said radiation detecting cassette comprises 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.

5. A medical system according to claim 1, wherein said radiation detecting cassette comprises a light-emitting device mounted on a surface of said casing,

wherein said cassette controller comprises a light-emission controller for controlling said light-emitting device 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 radiation detecting cassette comprises a display unit mounted on a surface of said casing,

wherein said cassette controller comprises a communication display controller for controlling said display unit to display transmission of said radiation image information during said period of time in which said communication unit is transmitting said radiation image information.

7. A radiation detecting cassette comprising:

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 transmitted at least during a period of time in which said communication unit is transmitting said radiation image information, 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.

8. A radiation detecting cassette according to claim 7, wherein the device is a battery pack housed in said casing.

9. A radiation detecting cassette according to claim 7, wherein the device is a power cable connected to a connector housed in said casing.

10. A radiation detecting cassette according to claim 7, wherein the device is a communication cable connected to a connector housed in said casing.
