摘要： A system and method for generating X-rays are disclosed. The method may include emitting an electron beam from a cathode to a focal track of a rotating target. The method may further include deflecting the electron beam onto a first region of the focal track at a first time, and deflecting the electron beam onto a second region of the focal track at a second time. The first region of the focal track may be separated from the second region of the focal track. The method may further include generating X-rays in response to the electron beam deflected onto the first region of the focal track or onto the second region of the focal track.

摘要： Systems and methods are provided for generating X-ray pulses during X-ray imaging. A high voltage of an X-ray tube is automatically switched off. The tube voltage decays and upon reaching a predefined threshold value of the tube voltage or a predefined waiting time after switching off the high voltage, a grating voltage of a grating arranged between an emitter and an anode of the X-ray tube is automatically switched on. No electrons reach the anode from the emitter, and the tube current drops to the value zero.

摘要： A signal relay device comprises a first connection I/F, to which an emission switch is connected, a second connection I/F, to which an emission signal I/F of an electronic cassette is connected, and a third connection I/F, to which a switch I/F of a source control device is connected, and a signal processing unit. The signal processing unit generates an emission execution signal during a time period in which an emission command signal from the emission switch and an emission enable signal from the electronic cassette are inputted. The source control device drives an X-ray tube to allow X-ray emission while the emission execution signal is inputted.

摘要： A radiation imaging apparatus includes a pixel array including pixels for detecting radiation and column signal lines, a detector for detecting signals that appear in the column signal lines, and a controller. Each pixel includes a conversion element for converting radiation into an electrical signal and a switch for connecting the conversion element and a column signal line. In a state in which the switches of the pixels irradiated with radiation are open, the detector detects, as a radiation signal, a signal appearing in at least one column signal line. The controller converts an integrated value of the radiation signal into an integrated irradiation amount of radiation. The controller determines, based on the radiation signal and a signal read out by the detector from at least one pixel in a state in which the switch of the at least one pixel of the pixels is closed, a conversion coefficient to convert the integrated value into the integrated irradiation amount.
