Multifocal X-ray bulb tube and multifocal X-ray imaging system

Abstract

The invention is suitable for the field of medical equipment, and provides a multifocal X-ray bulb tube and a multifocal X-ray imaging system. The multifocal X-ray bulb tube comprises a tube sleeve and a tube core and a bearing end located inside the tube sleeve. The inside of the tube core is a vacuum environment. A cathode terminal and an anode terminal are arranged inside the tube core. A powersupply interface assembly is arranged on the tube sleeve. The power supply interface assembly comprises at least one cathode power supply interface connected with the cathode terminal and at least two anode power supply interfaces connected with the anode terminal. The bearing end comprises a rotating shaft, and the anode end is installed on the rotating shaft. The anode terminal comprises at least two anode targets which can rotate with the rotating shaft, and the anode targets are correspondingly connected with the anode power supply interface in a one-to-one way. The cathode terminal comprises at least one electron generation source connected with the cathode power supply interface. Each electron generation source emits electrons to bombard the corresponding anode targets to radiate X-rays. The multifocal X-ray bulb tube can replace a plurality of single-focus bulb tubes and reduce production and maintenance cost.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a multi-focus X-ray tube and a multi-focus X-ray imaging system. Background technique [0002] The X-ray tube is the core component that works at high voltage to generate X-rays. It contains two electrodes: one is a filament or other electron generation source used to generate and emit electrons, as a cathode, and the other is used to accept high-speed electrons. The bombarded target is used as an anode, and both poles are sealed in a high-vacuum glass or metal shell. According to different uses, it can be divided into medical X-ray tubes and industrial X-ray tubes. Medical X-ray tubes are mainly used for diagnosis and treatment, and industrial X-ray tubes are mainly used for non-destructive testing of materials, structural analysis, spectral analysis and Film exposure, etc. [0003] The position of the anode bombarded by electrons in the X-ray tube can be regarded as a focal p...

Problems solved by technology

[0003] The position of the anode bombarded by electrons in the X-ray tube can be regarded as a focal point. The existing X-ray tubes are all single-focus structures. In some occasions, multi-focus exposure is required, such as the diagnosis and treatment of cardiovascular and cerebrovascular diseases. , usually multiple single-focus X-ray tubes are used, and each single-focus X-ray tube needs to be equipped with a set of control system and image processing system. The exposure time is long, motion artifacts are prone to occur, and the cost is high. The integration level limited
