摘要： An X-ray diagnostic apparatus and an auxiliary device, such as an X-ray photographing device which requires a fixedly predetermined exposure time, and which contains a control circuit for the X-ray dosage power or output with reference to a patient; a dosage output measuring arrangement; a comparator element connected to the latter for comparing the actual value of the X-ray dosage output with a reference value, which effects optimum film darkening for each particular exposure time; and adjusting means controlled by the output signal of the comparator element for adjustment of the X-ray tube voltage for equating the actual value of the dosage output with the reference value.

摘要： An analog voltage multiplier in combination with an operational integrator. The overall circuit measures the energy input to an X-ray generator tube and compensates for its thermal dissipation. If safe bounds are exceeded, the tube is shut down. These circuits are independent of the normal control circuits so that the tube and patient are protected.

摘要： A method for generating X-ray radiation, the method including providing a liquid target in a chamber, directing an electron beam towards the liquid target such that the electron beam interacts with the liquid target to generated X-ray radiation, estimating a number of particles produced from the interaction between the electron beam and the liquid target by measuring a number of positively charged particles in the chamber and eliminating a contribution from scattered electrons to the estimated number of particles, and controlling the electron beam, and/or a temperature in a region of the liquid target in which the electron beam interacts with the target, such that the estimated number of particles is below a predetermined limit. Also, a corresponding X-ray source.

摘要： An X-ray imaging apparatus operates by selecting an appropriate exposure sensitivity corresponding to the X-ray detector to be used. In the apparatus, an exposure sensitivity corresponding to the flat panel detectors used for an X-ray imaging is selected from multiple exposure sensitivities stored in an exposure sensitivity memory unit of the console, and the selected exposure sensitivity is displayed on the display unit of the high-voltage unit. An exposure control is executed based on the exposure sensitivity corresponding to the flat panel detectors used for the X-ray imaging, which is selected from multiple exposure sensitivities stored in an exposure sensitivity memory unit. The exposure control unit of the high-voltage unit suspends the X-ray irradiation from the X-ray tube when an integrated value of the X-ray detected by the X-ray dose sensor reaches to the setting-value set relative to the selected exposure sensitivity.
