Abstract

A radiation conversion device is driven by an on-board battery, detects radiation that has passed through a subject, and converts the radiation into image information. A charging cradle to which the radiation conversion device is connected carries out a charging process on the battery. The radiation conversion device includes a signal transmitting unit for transmitting image information by wireless communications to an external apparatus, a transmission suspension unit for monitoring a transmission state of the image information by the signal transmitting unit and suspending transmission of the image information when a transmission error is generated, and a suspension release unit for releasing suspension of transmission of the image information when the radiation conversion device is connected to the charging cradle. The signal transmitting unit transmits the image information to the external apparatus when suspension of transmission of the image information has been released.

Claims

1. A radiation conversion device driven by an on-board battery mounted therein, for detecting radiation that has passed through a subject and converting the radiation into image information, comprising:

a signal transmitting unit for transmitting the image information by wireless communications to an external apparatus;

a transmission suspension unit for monitoring a transmission state of the image information by the signal transmitting unit and suspending transmission of the image information when a transmission error is generated; and

a suspension release unit for releasing suspension of transmission of the image information when the radiation conversion device is connected to a charging cradle that charges the battery,

wherein the signal transmitting unit transmits the image information to the external apparatus when suspension of transmission of the image information has been released.

2. The radiation conversion device according to claim 1, wherein the signal transmitting unit transmits the image information to the external apparatus through the charging cradle.

3. The radiation conversion device according to claim 2,

wherein the signal transmitting unit transmits the image information to the charging cradle by wireless communications, and

the charging cradle transmits the image information by wire communications to the external apparatus.

4. The radiation conversion device according to claim 1, further comprising a display unit for displaying a transmission state of the image information.

5. The radiation conversion device according to claim 4, wherein the display unit displays a residual charge amount of the battery.

6. The radiation conversion device according to claim 1, wherein when the suspension of transmission of the image information is released by connecting the radiation conversion device to the charging cradle, the signal transmitting unit transmits the image information to the external apparatus by wireless communications.

7. A radiation image capturing system comprising:

a radiation conversion device driven by an onboard battery mounted therein, for detecting radiation that has passed through a subject and converting the radiation into image information; and

a charging cradle to which the radiation conversion device is connected for carrying out a charging process on the battery,

the radiation conversion device further comprising;

a signal transmitting unit for transmitting the image information by wireless communications to an external apparatus;

a transmission suspension unit for monitoring a transmission state of the image information by the signal transmitting unit and suspending transmission of the image information when a transmission error is generated; and

a suspension release unit for releasing suspension of transmission of the image information when the radiation conversion device is connected to a charging cradle that charges the battery,

wherein the signal transmitting unit transmits the image information to the external apparatus when suspension of transmission of the image information has been released.

8. The radiation image capturing system according to claim 7, wherein the signal transmitting unit transmits the image information to the external apparatus through the charging cradle.

9. The radiation image capturing system according to claim 7, wherein the radiation conversion device comprises a display unit for displaying a transmission state of the image information.

10. The radiation image capturing system according to claim 9, wherein the display unit displays a residual charge amount of the battery.

11. The radiation image capturing system according to claim 7,

wherein the signal transmitting unit transmits the image information to the charging cradle by wireless communications, and

the charging cradle transmits the image information by wire communications to the external apparatus.

12. The radiation image capturing system according to claim 7, wherein when the suspension of transmission of the image information is released by connecting the radiation conversion device to the charging cradle, the signal transmitting unit transmits the image information to the external apparatus by wireless communications.
