Title:
RADIOGRAPHY SYSTEM AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/217770
Kind Code:
A1
Abstract:
This radiography system comprises: a radiography device including a sensor unit for acquiring a radiograph and capable of receiving electric power in a contactless manner; and a power feeding device capable of feeding the electric power to the radiography device in a contactless manner, wherein during a period during which the power feeding device changes a power feeding frequency for feeding the electric power to the radiography device and thereby an influence on a signal acquired by the radiography device from the sensor unit according to the change in the power feeding frequency occurs, the power feeding device feeds the electric power to the radiography device at a constant power feeding frequency.
