Abstract: An X-ray tube for generating two focal spots displaced with respect to each other and a medical device using such X-ray tube are proposed. The X-ray tube (1) comprises a cathode (7) and an anode (9) wherein the cathode (7) comprises a first electron emitter (15) adapted for emitting a first electron beam (17) for generating a first focal spot (25) on the anode (9) and a second electron emitter (19) for emitting a second electron beam (21) for generating a second focal spot (27) on the anode (9). Therein, each electron emitter (15, 19) comprises an associated switchable grid (37, 39) for blocking the respective emitted electron beam (17, 21). In order to realize a desired displacement of the first and second focal spots (25, 27) in a y-direction, the first and second electron emitters (15, 19) may be displaced in the z-direction. Due to the focal spots (25, 27) being displaced in y-direction, an overall resolution of for example a high quality CT scanner may be significantly enhanced.

Abstract: An x-ray generator includes a voltage source and a voltage divider network coupled thereto, a housing, and an insulator carried within the housing. An emitter cathode is carried within the housing and emits electrons and undesirable conductive particles. In addition, there is a shielding electrode carried within the housing downstream of the emitter cathode and coupled to the voltage divider network. A target is carried within the housing downstream of the at least one shielding electrode. The voltage divider is configured so that the emitter cathode and the shielding electrode have a voltage difference therebetween such that an electric field generated in the housing accelerates electrons emitted by the emitter cathode to toward the target. The shielding electrode is shaped to capture the undesirable conductive particles emitted by the emitter cathode that would otherwise strike the insulator.

Abstract: An inverter circuit is shared by respective drive circuits that supply a predetermined voltage to a lens electrode and a grid electrode, or to a lens electrode and a cathode electrode. A DC voltage obtained by full-wave rectifying a pulse train output from the inverter circuit is supplied to the lens electrode, a DC voltage obtained by half-wave rectifying a pulse train output from the inverter circuit is supplied to the grid electrode or cathode electrode. At times of a first operation and a last operation of the inverter circuit during a period of generating X-rays, operations of the inverter circuit are controlled such that a trans circuit outputs a negative polarity voltage to the full-wave rectifying circuit and the half-wave rectifying circuit, respectively.
