The radiography apparatus includes: an irradiation unit having an irradiation opening through which radiation is emitted; an image receiving unit that has an image receiving surface receiving the radiation emitted from the irradiation unit; an arm that has one end at which the irradiation unit is rotatably supported and the other end at which the image receiving unit is supported in a posture in which the irradiation opening and the image receiving surface face each other; a solenoid that locks the rotation of the irradiation unit with respect to the arm in a facing posture in which the irradiation opening and the image receiving surface face each other; and a control unit that permits the moving image capture irradiation in a state in which the rotation of the irradiation unit is locked and prohibits the moving image capture irradiation in a state in which the rotation is unlocked.
Methods and systems for computed tomography tissue imaging
A method is provided to perform an imaging scan on a target tissue. The imaging scan includes generating a signal directed at a portion of a target tissue using a collimator that includes a slot, wherein a source of a signal assembly is incoherently interrupted. The method also includes receiving at least a portion of the signal from the portion of the target tissue at a linear signal detector positioned directly opposite from the signal assembly with respect to the target tissue, and simultaneously translating the linear signal detector and adjusting a width of the at least one slot of the collimator such that a fan width of the signal at the linear signal detector corresponds to a width of a detector window disposed in the linear signal detector. The method also includes rotating a stage about the target tissue, and repeating performing the imaging scan on the target tissue.
X-RAY IMAGING DEVICE, X-RAY IMAGING SYSTEM, AND METHOD OF CONTROLLING X-RAY IMAGING DEVICE
According to an embodiment, an X-ray imaging device includes an irradiator, an exposure switch device, and a control device. The irradiator irradiates a subject placed on a bed with X-rays.
