20110227750 | Radiation imaging system having radiation imaging cassette and console device, and radiation imaging program - A radiation imaging system includes a radiation imaging cassette and a console device. A communication mode between the cassette and the console device is switchable between a wired mode and a wireless mode. Due to shortage of a battery of the cassette, the communication mode is switched to the wired mode to start charging the battery and send image data from the cassette to the console device through a cable. The console device has first and second judging sections. The first judging section judges whether or not a charge level of the battery exceeds a predetermined threshold value. The second judging section judges whether or not radiography is in progress. If it is judged that the charge level of the battery exceeds the predetermined threshold value and the radiography is not in progress, a window that indicates permission for switching to the wireless mode is displayed on a monitor. | 09-22-2011 |
20110235782 | Radiation imaging system, console, and radiation imaging program - A radiation imaging system has a radiation generation device, an FPD cassette, and a console. The console judges whether or not the FPD cassette is in a good communication state repeatedly once every thirty seconds. Upon receiving a radiography order, the console changes repetition intervals from thirty seconds to three seconds, and keeps judging the communication state of the FPD cassette. The repeated judgment is continued until a shutter button is pressed. Upon the press of the shutter button, the radiation generation device emits radiation to carry out radiography. | 09-29-2011 |
20110238343 | Apparatus, system and method of managing battery level of wirelessly communicable radiographic cassette - A current charge level of a battery presently used for supplying a wirelessly communicable cassette is detected and transmitted to a console of an X-ray imaging apparatus. In the console, a power consumption calculator calculates an estimated amount of power consumption by the cassette for each of received orders for inspections. When a new order for inspection is received, or one of the ordered inspections is canceled or finished, or the battery of the cassette is replaced, the last inspection until which the presently used battery can effectively supply the cassette is determined among the ordered inspections on the basis of the detected current charge level and the estimated power consumption amounts for the individual inspections, to display a message prompting to replace the presently used battery before the end of the determined last inspection. | 09-29-2011 |

20130058453 | RADIOGRAPHY SYSTEM AND RADIATION SOURCE CONTROLLER - A source controller unit for controlling an x-ray source is provided with a detection signal interface for receiving detection signals from detective pixels of an electronic cassette or an integrated value of the detection signals only, or an interface for receiving a radiation stopping signal only. The source controller unit receives other radiation signals than the radiation stopping signal, such as a radiation admitting signal, through a radiation signal interface. The source controller unit uses the detection signals, the integrated value thereof, or the radiation stopping signal as exposure control signals for stopping radiation from the x-ray source. Since the exposure control signals are received on the specific interface therefor, the source controller unit does not need signal sorting operation nor receive different kinds of signals at the same time, improving the speed of radiation stopping procedure. | 03-07-2013 |
20130058454 | RADIOGRAPHIC SYSTEM, AUTOMATIC EXPOSURE CONTROL METHOD OF RADIOGRAPHIC SYSTEM, AND RADIOLOGICAL IMAGE DETECTOR - When an AEC sensor is changed, the same AEC as before changing the AEC sensor is carried out without modifying an existing apparatus. A storage and search unit of a console acquires a source ID and searches for and extracts position information of a detection field of an old AEC sensor corresponding to the acquired source ID from source information of a storage device. An electronic cassette includes plural detection pixels as a new AEC sensor short-circuited to signal lines without passing through TFTs in the same imaging plane as pixels. A detection field selecting circuit of an AEC unit of the electronic cassette selects a detection signal from the detection pixel existing at the position of the detection field of the old AEC sensor among the detection signals of the plural detection pixels. | 03-07-2013 |

20140177798 | RADIATION IMAGING SYSTEM, COMMUNICATION METHOD OF RADIATION IMAGING SYSTEM, AND RADIOGRAPHIC IMAGE DETECTING DEVICE - A communication section having a relatively high communication speed is used for communicating a detection signal or an emission stop signal between a source control device and an electronic cassette. The detection signal is outputted from a detection pixel of the electronic cassette. The emission stop signal depends on a comparison result between an integrated value of the detection signal and an emission stop threshold value. On the other hand, a wireless communication section having a lower communication speed than that of the detection signal and the emission stop signal is used for communicating image data and the like between the electronic cassette and a console. | 06-26-2014 |
20140205066 | RADIATION IMAGING SYSTEM AND OPERATING METHOD THEREOF, AND RADIATION IMAGE DETECTING DEVICE - A measurement area selection circuit has an irradiation field determination unit, an object area determination unit, and a measurement area determination unit. The irradiation field determination unit determines an irradiation field of an imaging surface of an FPD. The object area determination unit determines an object area from a comparison result between a first expected received dose of a directly exposed area and dose detection signals of detection pixels situated in the irradiation field. The measurement area determination unit determines a measurement area, which corresponds to a region of interest, from a comparison result between a second expected received dose of the measurement area and the dose detection signals of the detection pixels situated in the irradiation area and the object area. The dose detection signals of the detection pixels situated in the measurement area are used for AEC. | 07-24-2014 |
20140211922 | RADIATION IMAGING SYSTEM AND CONTROL METHOD THEREOF, AND RADIATION IMAGE DETECTING DEVICE - Upon input of a synchronization signal, which indicates a start of an X-ray emission, from a source control unit for controlling an X-ray source, an electronic cassette makes an FPD start an accumulation operation and measurement of an X-ray dose. The electronic cassette and a console command their communicators to stop communication of any signal other than a stop signal, which stops the X-ray emission from the X-ray source, during the accumulation operation of the FPD. As soon as the X-ray dose has reached a predetermined threshold value, the electronic cassette transmits the stop signal to the source control unit through the console. A delay in transmission of the stop signal due to communication congestion or signal collision does not occur, because the electronic cassette and the console stop the communication of the signal other than the stop signal. | 07-31-2014 |
