Abstract:
A radiation imaging system is equipped with a radiation imaging apparatus and a control apparatus. The radiation imaging apparatus reads out image signals from a radiation detecting section that detects radiation which has passed through a subject, and outputs the read out image signals as wireless signals. The control apparatus outputs predetermined control signals to the radiation imaging apparatus as wireless signals. A second wireless communicating section of the control apparatus decreases the signal strength of communications to be lower during readout of the image signals than at times other than during readout of image signals.
Abstract:
An object of the present invention is to provide a liquid crystal display, which can surely perform an instillation process used when liquid crystal is sealed between substrates in a cell process, and a fabrication method thereof. A liquid crystal display comprises a sealing material made of a photo-curing type material which seals liquid crystal sandwiched between substrates, and a shading film having a shading area which overlays a red-colored layer transmitting red light, a green-colored layer transmitting green light and a blue-colored layer transmitting blue light, wherein only the blue-colored layer is formed in an area of the shading film contacting with the sealing material and the photo-curing type material of the sealing material is structured to have a light reactive area for a wavelength of blue color band.
Abstract:
A cassette device includes a radiation detecting cassette having a radiation detector therein for detecting radiation having passed through a subject and converting the detected radiation into radiation image information, a transmission and reception controller connected to the radiation detector for transmitting the radiation image information to an image processor by way of wireless communications, and a cassette storage bag for storing the radiation detecting cassette therein. The cassette storage bag includes an antenna incorporated therein for transmitting the radiation image information from the transmission and reception controller to the image processor by way of wireless communications. The transmission and reception controller and the antenna are capable of being electrically connected to each other through detachable connectors.
Abstract:
The power consumption of a battery for supplying electric power to a cassette having a radiation detector for detecting radiation image information is greatly reduced. When a cassette transceiver of the cassette starts transmitting the radiation image information to a console transceiver of a console, the cassette transceiver changes the gain of a variable-gain amplifier to change a transmission radio-wave intensity, and transmits a test signal at the changed transmission radio-wave intensity. When the console transceiver receives the test signal, the console transceiver transmits a reception acknowledgement signal generated by a reception acknowledgement signal generator. In response to the reception acknowledgement signal, the cassette transceiver sets its own transmission radio-wave intensity to a value at the time the cassette transceiver received the reception acknowledgement signal, and transmits the radiation image information at the set transmission radio-wave intensity.
Abstract:
A radiation image capturing system detects the position of a radiation detecting cassette disposed below a patient and the position of a radiation source for emitting a radiation, based on the differences between the propagation times of radio waves emitted from an antenna device to an image capturing apparatus and the radiation detecting cassette. Based on the detected positions, the relative positions of the image capturing apparatus and the radiation detecting cassette are calculated, and then compared with each other by a position determining unit to judge how the image capturing apparatus is positioned with respect to the radiation detecting cassette. If the image capturing apparatus is not positioned in head-on facing relation to the radiation detecting cassette, then a warning is issued, and an actuating mechanism moves the image capturing apparatus to an appropriate position.
Abstract:
A radiation imaging cassette is provided with two types of communicating means within a housing. One is a wireless communicating means for communicating wirelessly with an imaging control means, and the other is a wired communicating means for communicating with the imaging control means. A metal detecting sensor for detecting metal in the periphery of the housing is also provided. A control section ceases the operation of the wireless communicating means and causes the radiation imaging cassette to communicate with imaging control means using the wired communication means, in response to detection of metal by the metal detecting sensor. Thereby, imaging operations are enabled to be performed safely even in cases that patients with pacemakers are in the vicinity of the radiation imaging cassette.
Abstract:
A transceiver of a radiation detecting cassette sends cassette ID information stored in a cassette ID memory to a transceiver of a console via a transceiver of an image capturing apparatus by way of wireless communications. An ID determining unit determines whether cassette ID information which matches the cassette ID information received by the transceiver is stored in a cassette ID memory or not. If the ID determining unit judges that both cassette ID information match each other, the transceiver sends the cassette ID information and an activation instruction signal to the transceiver by way of wireless communications.
Abstract:
In a transmission, a lubrication oil retention section is formed to surround an area around a circumferential part of a first gear that ranges from a lubrication oil storage region to the outside of the lubrication oil storage region. In the lubrication oil retention section, the lubrication oil scooped up by the rotation of the first gear is retained between the lubrication oil retention section and the first gear at the outside of the lubrication oil storage region. The lubrication oil retention section enables the first gear to splash the lubrication oil retained at the outside of the lubrication oil storage region, toward a receiver that flows the lubrication oil to various sliding parts of the transmission.
Abstract:
A radiation detecting cassette is disposed in a desired position between a bed and a patient in an operating room. After a detector-side connector and a bed-side connector are connected to each other by a cable, an image capturing apparatus captures and records radiation image information of the patient in a radiation detector. The recorded radiation image information is transmitted from a transceiver of the bed to a console by way of wireless communications in a communication range selected by a selector of the bed, then processed by the console, and transmitted to a display device, which displays a radiation image based on the supplied radiation image information.
Abstract:
The present invention relates to a radiation image capturing system. A radiation detector of a radiation detecting cassette detects a radiation that has passed through a patient, and an accumulated exposed radiation dose calculator calculates an accumulated exposed radiation dose by accumulating radiation image information detected by the radiation detector, at every image capturing. The calculated accumulated exposed radiation dose is transmitted, together with cassette ID information, to a console. In the console, a status determining unit compares the accumulated exposed radiation dose with an allowable accumulated exposed radiation dose for the radiation detecting cassette to determine the status of the radiation detecting cassette, and issues a warning based on the determined status.
