Radiation detecting apparatus, radiographic image capturing system, and radiographic image capturing method
First Claim
1. A radiation detecting apparatus comprising:
- a radiation detector for detecting radiation applied from an external image capturing apparatus and transmitted through a subject;
a contactless power receiver for receiving electric power supplied contactlessly from an external contactless power feeder and supplying the received electric power to a power supply;
an A/D converter for performing an A/D conversion to convert analog radiographic image information, which has been generated based on the radiation applied to the radiation detector, into digital radiographic image information;
an end-of-A/D-conversion determining unit for determining whether the A/D conversion is finished or not; and
a charging controller for stopping the contactless power feeder from supplying electric power contactlessly after the external image capturing apparatus has started to capture a radiographic image until the end-of-A/D-conversion determining unit judges that the A/D conversion is finished.

Abstract
An electronic cassette in a radiographic image capturing system includes a radiation detector for detecting radiation applied from an image capturing apparatus and transmitted through a patient, a contactless power receiver for receiving electric power supplied contactlessly from a power feeder and supplying the electric power to a battery, an A/D converter for performing an A/D conversion to convert analog radiographic image information generated based on the radiation applied to the radiation detector into digital radiographic image information, an end-of-A/D-conversion determining unit for determining whether the A/D conversion is finished or not, and a charging controller for stopping the power feeder from supplying electric power contactlessly after the image capturing apparatus has started capturing images until the end-of-A/D-conversion determining unit judges that the A/D conversion is finished.

6. A radiographic image capturing system comprising:
-
an image capturing apparatus for applying radiation to a subject; a radiation detecting apparatus including a radiation detector for detecting the radiation transmitted through the subject, an A/D converter for performing an A/D conversion to convert analog radiographic image information, which has been generated based on the radiation applied to the radiation detector, into digital radiographic image information, and a power supply for supplying electric power to the radiation detector; a contactless power feeder disposed in the radiation detecting apparatus, for supplying electric power contactlessly to a contactless power receiver which supplies electric power to the power supply; a controller for controlling the image capturing apparatus, the radiation detecting apparatus, and the contactless power feeder; an end-of-A/D-conversion determining unit for determining whether the A/D conversion is finished or not; and a charging controller for stopping the contactless power feeder from supplying electric power contactlessly after the image capturing apparatus has started to capture a radiographic image until the end-of-A/D-conversion determining unit judges that the A/D conversion is finished. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)

15. A method of capturing a radiographic image of a subject by applying radiation to the subject, detecting the radiation with a radiation detector of a radiation detecting apparatus, and converting the detected radiation into radiographic image information with the radiation detector, comprising the steps of:
-
supplying electric power contactlessly to a power supply of the radiation detecting apparatus; and stopping supplying electric power contactlessly to the power supply after image-capturing by the radiation has been started at least until an A/D conversion of the radiographic image information detected by the radiation detector is finished.
