An X-ray CT apparatus of an embodiment acquires projection data of a subject based on X-ray detection data according to biometric information synchronous scanning and generates a CT image of the subject based on the projection data. The X-ray CT apparatus includes a first acquisition unit, a determination unit, and a second acquisition unit. The first acquisition unit acquires biometric information of the subject at a timing when the biometric information synchronous scanning has been performed. The determination unit determines, as priority data, detection data that is a target for which data transfer will be preferentially performed among X-ray detection data acquired in the biometric information synchronous scanning based on the biometric information. The second acquisition unit acquires the priority data from a storage device that holds the detection data.

Embodiments provide a stationary X-ray source for a multisource X-ray imaging system for tomographic imaging. The stationary X-ray source includes an array of thermionic cathodes and, in most embodiments a rotating anode. The anode rotates about a rotation axis, however the anode is stationary in the horizontal or vertical dimensions (e.g. about axes perpendicular to the rotation axis). The elimination of mechanical motion improves the image quality by elimination of mechanical vibration and source motion; simplifies system design that reduces system size and cost; increases angular coverage with no increase in scan time; and results in short scan times to, in medical some medical imaging applications, reduce patient-motion-induced blurring.

A radiation imaging system comprises a sensor unit of a radiation imaging device, detecting an incident radiation R irradiated from a radiation generator; an arithmetic unit calculating an accumulated dose of the radiation detected by the sensor unit; and an imaging control unit outputting an irradiation stop signal for stopping the irradiation of the radiation R to the radiation generator when the accumulated dose reaches a threshold or more, wherein the imaging control unit sets the threshold based on a dose rate of the radiation R determined based on a relationship between the accumulated dose and a time, and a delay time from a time of outputting the irradiation stop signal to a time of stopping the irradiation of the radiation of the radiation generator.
