Abstract
A housing of an electronic cassette has an inclined surface which is formed between a side surface and a rear surface thereof and inclined relative to the side surface and the rear surface. An antenna opening through which a radio wave is transmitted is formed on the inclined surface. Since the antenna opening is formed on the inclined surface, the antenna opening is not blocked by a rear plate of a holder of an upright radiographic stand or a supine radiographic stand, and the antenna opening is not blocked by a side panel of an outer grid. Both in the case where the electronic cassette is set to the holder and in the case where the outer grid is attached to the electronic cassette, it is possible to perform stable wireless communication.
Claims12
An electronic cassette comprising:
- an image detector for detecting a radiation image of a subject based on radiation having been transmitted through the subject;
- a housing for housing the image detector, the housing having a front surface on which the radiation is incident, a rear surface facing the front surface, and four side surfaces, and the housing having an inclined surface which is formed at least between one of the side surfaces and the rear surface and inclined relative to the one of the side surfaces and the rear surface;
- an antenna disposed inside the housing, for use in wireless transmission of at least the radiation image via radio waves;
- and
- an antenna opening through which the radio waves are transmitted, at least part of the antenna opening being formed on the inclined surface.
An electronic cassette comprising:
- an image detector for detecting a radiation image of a subject based on radiation having been transmitted through the subject;
- a housing for housing the image detector, the housing having a front surface on which the radiation is incident, a rear surface facing the front surface, and four side surfaces, and the housing having an inclined surface which is formed at least between one of the side surfaces and the rear surface and inclined relative to the one of the side surfaces and the rear surface;
- first and second antennas disposed inside the housing, for use in wireless transmission of at least the radiation image via radio waves;
- and
- first and second antenna openings through which the radio waves are transmitted, at least a part of each of the first and second antenna openings being formed on the inclined surface,
- wherein the first antenna is disposed correspondingly to the first antenna opening and the second antenna is disposed correspondingly to the second antenna opening.
