A radiographic imaging device includes: a radiation detector including plural pixels, each including a sensor portion and a switching element; a detection unit that detects a radiation irradiation start if an electrical signal caused by charges generated in the sensor portion satisfies a specific irradiation detection condition, and/or if an electrical signal caused by charges generated in a radiation sensor portion that is different from the sensor portion satisfies a specific irradiation detection condition; and a control unit that determines whether or not noise caused by external disturbance has occurred after the detection unit has detected the radiation irradiation start, and if the noise has occurred, that stops a current operation of the radiation detector, and causes the detection unit to perform detection.

In an automatic exposure control method for X-ray imaging, a visible light image of a subject under test is acquired, an initial region of interest (ROI) is defined on the visible light image, the subject under test is pre-exposed with a set pre-exposure dose to obtain a first image, an ROI on the first image is defined based on the initial ROI, a reference pixel value is defined based on the ROI, and a main exposure dose for an actual exposure is calculated according to the reference pixel value. With the imaging quality guaranteed, a physical automatic exposure control (AEC) chamber may be omitted, and the number, positions and sizes of ROIs can be adjusted according to the actual requirements.

A system includes one or more storage devices storing a set of instructions and at least one processor in communication with the storage device. When executing the instructions, the at least one processor is configured to cause the system to obtain a first operating state of an X-ray imaging device, and obtain a first input from a user via a terminal, the first input being associated with a second operating state of the X-ray imaging device. The at least one processor may further cause the system to determine whether the first input satisfies a switch condition. Upon a determination that the first input satisfies the switch condition, the at least one processor may further cause the system to transmit a first instruction to switch the X-ray imaging device from the first operating state to the second operating state.

A method for controlling a radiological apparatus through the use of: a) a control unit adapted to activate X-ray emission from an X-ray emitter of the radiological apparatus at the beginning of an exposure and deactivating X-ray emission from said X-ray emitter subsequently, and b) an X-ray transducer associated with an image detector of the radiological apparatus. Said control unit repeatedly determines a predicted value of total X-ray dose based on a signal received from said X-ray transducer, and said control unit deactivates the X-ray emission based on at least said predicted value. To determine said predicted value, said control unit repeatedly performs total X-ray dose estimates according to a model, and one or more parameters of said model are determined and modified during operation of the radiological apparatus.

An X-ray imaging system (XI) configured for phase contrast and/or dark-field imaging The system comprises an X-ray source (XS) operable to cause X-radiation to emanate from a focal spot (SF) of the source (XS) and an X-ray sensitive detector (D) operable to SMF detect the X-radiation after interaction of said X-radiation with an object to be imaged, if present, between the X-ray source and the detector (D). A control logic (CL) is operable to cause the X-ray imaging apparatus to operate in any one of two modes, an object image acquisition mode and a scattering measurement mode. When in scattering measurement mode, the X-radiation receivable at the detector comprises a higher proportion of scattering radiation than in X-radiation receivable when the system is in object image acquisition mode.

An X-ray diagnosis apparatus according to an embodiment includes an X-ray limiter having four diaphragm blades; and a console on which four physical operating units that correspond to the four diaphragm blades are placed at four positions. When viewed from the side of the operator of the console, the four operating units are placed on the far side, the near side, the left side, and the right side. The far-side operating unit, the near-side operating unit, the left-side operating unit, and the right-side operating unit correspond to the upper diaphragm blade, the lower diaphragm blade, the left-side diaphragm blade, and the right-side diaphragm blade, respectively, with reference to an X-ray image displayed in a display. An operation of moving the far-side operating unit in the far-side direction results in the movement of the upper diaphragm blade in the upward direction of the X-ray image displayed in the display, and an operation of moving the far-side operating unit in the near-side direction results in the movement of the upper diaphragm blade in the downward direction of the X-ray image displayed in the display. An operation of moving the near-side operating unit in the far-side direction results in the movement of the lower diaphragm blade in the upward direction of the X-ray image displayed in the display, and an operation of moving the near-side operating unit in the near-side direction results in the movement of the lower diaphragm blade in the downward direction of the X-ray image displayed in the display. An operation of moving the left-side operating unit in the leftward direction results in the movement of the left-side diaphragm blade in the leftward direction of the X-ray image displayed in the display, and an operation of moving the left-side operating unit in the rightward direction results in the movement of the left-side diaphragm blade in the rightward direction of the X-ray image displayed in the display. An operation of moving the right-side operating unit in the leftward direction results in the movement of the right-side diaphragm blade in the leftward direction of the X-ray image displayed in the display, and an operation of moving the right-side operating unit in the rightward direction results in the movement of the right-side diaphragm blade in the rightward direction of the X-ray image displayed in the display.

A CPU acquires a distance image or a visible light image captured by a TOF camera or a visible light camera that has, as an imageable region, a region including an irradiation region which is a space in which a breast of a subject imaged by a mammography apparatus is irradiated with radiation emitted from a radiation source and detects whether or not a foreign object other than an object to be imaged is present in the irradiation region on the basis of the distance image or the visible light image.
