摘要： Provided is a radiation irradiation device that prevents degradation of a battery resulting from a high current that flows when radiation is generated. The radiation irradiation device includes a radiation generating part that generates radiation; a battery part that supplies electric power to the radiation generating part; and an exposure switch that receives an emission instruction of the radiation from the radiation generating part. The battery part has a lithium ion battery, a capacitor connected in parallel to the lithium ion battery, a switch element that performs switching from a state where electric power is supplied from the lithium ion battery to the capacitor to a state where electric power is supplied from the capacitor to the radiation generating part. The switch element switches between the states of the electric power supply according to an instruction received in the exposure switch.

摘要： The invention provides a radiation irradiation device that can appropriately manage the residual capacity of a battery without being influenced by the internal resistance of the battery. The radiation irradiation device includes a radiation generating part that generates radiation; a battery part that supplies electric power to the radiation generating part; and a residual capacity calculation part that calculates the residual capacity of the battery part. The residual capacity calculation part calculates the residual capacity of the battery part on the basis of a current flowing into the battery part, an internal resistance of the battery part, and a voltage of the battery part.

A compact x-ray source (110) can comprise a single transformer core (101) to transfer alternating current from two alternating current sources (104a, 104b) to an electron emitter (43) and a high voltage generator (107). A compact x-ray source (120) can comprise a high voltage sensing resistor (R1) disposed on a cylinder (41) of an x-ray tube (40).

摘要： Methods and systems are generally described for measuring a voltage used by an imaging system to generate radiation used in imaging. In embodiments, different datasets are acquired using different degrees of attenuation of the radiation. The differently attenuated datasets are processed to derive a ratio of the differential attenuation. The attenuation ratio is processed to derive a measure of the voltage used by the imaging system to generate the radiation used to acquire the different datasets.

摘要： A high-voltage (HV) generator of an X-ray device comprises a high-voltage measurement device. The measurement device comprises a compact component integrating both the measurement resistor and the capacitors enabling both the protection of said resistor and the elimination of the parasitic effects of the generator. The capacitors are made on insulating plates preferably made of ceramic, a succession of metallized strips and insulating strips. The plates are positioned relative to one another in such a way that the capacitors are discrete and series-mounted. To do this, between two successive plates, the metallized strips of the bottom plate overlap two metallized strips of the plate directly above.
