Electronic cassette for radiographic imaging

摘要

An electronic cassette for radiographic imaging includes a radiation imaging detector for detecting X-rays from an object and creating an X-ray image of the object. A battery supplies the radiation imaging detector with power. A power receiver wirelessly receives power from a wireless power transmission apparatus for charging the battery. A housing is formed from an electrical conductor, for containing the radiation imaging detector and the power receiver. A path opening is formed in the housing, and disposed between the power receiver and the wireless power transmission apparatus. A cover device is formed from a material having electrical insulating property and thermal conductivity, for closing the path opening, and conducting heat of the power receiver to the housing for dissipation. Preferably, the cover device contains synthetic resin. Also, a profile line of the path opening is at least partially curved.

主权项

1. An electronic cassette for radiographic imaging comprising:
a radiation imaging detector for detecting a radiation image of an object according to radiation from said object; a battery for supplying said radiation imaging detector with power; a power receiver for wirelessly receiving power from a wireless power transmission apparatus for charging said battery; a housing, formed from an electrical conductor, for containing said radiation imaging detector and said power receiver; a path opening, formed in said housing, and disposed in alignment with said power receiver; a cover device, formed from a material having electrical insulating property and thermal conductivity, for closing said path opening, and conducting heat of said power receiver to said housing for dissipation, said cover device including:
a cap plate for opposing to said wireless power transmission apparatus;a cover plate, disposed between said cap plate and said power receiver, and having a higher thermal conductivity than a thermal conductivity of said cap plate; a projection, formed to project from said cover plate along an edge of said cap plate, for directing heat of said power receiver outwards.
