Combined high-frequency high-pressure X-ray machine head

Abstract

The invention discloses a combined high-frequency high-pressure X-ray machine head which comprises an oil tank cover (1) and an oil tank body (2). An inside insulating frame (12) fixedly connected with the oil tank cover (1) is arranged inside the oil tank body (2). The inside insulating frame (12) is divided into a plurality of spaces through an arranged insulating partition plate and is fixedly provided with a plus-end dual-voltage rectifying unit (7), a minus-end dual-voltage rectifying unit (8), a filament transformer (9), a high-frequency high-pressure transformer (10) and an X-ray tube (11). The oil tank cover (1) is further provided with a wiring board unit (5) and a feed-through capacitor (6). The inside insulating frame (12) and the insulating partition plate are made of 10-mm-thick PP plates. The combined high-frequency high-pressure X-ray machine head is simple in structure, reasonable in design, safe and reliable and capable of effectively solving the problem that the machine head strikes a light easily when the machine head outputs the high-power X-ray source, and high-power X-rays can be output stably.

Description

technical field [0001] The invention belongs to medical equipment, and in particular relates to a combined high-frequency and high-pressure X-ray machine head for manufacturing an X-ray machine. Background technique [0002] The current combined X-ray machine head mainly includes power frequency machine, high frequency machine, and high frequency machine is divided into low power and high power. This kind of machine head is widely used in X-ray machines. The combined X-ray machine head is assembled on the frame of the X-ray machine and connected with other circuits to form a complete X-ray machine, which can be used in hospitals at all levels to combine human head, chest, abdomen, limbs and bones Ordinary photography and high-kilovolt photography were performed in standing, supine, and lateral positions. [0003] The combined X-ray head in the X-ray machine is particularly critical. Due to the large size, heavy weight and low output power of the combined power frequency X-...

AI Technical Summary

Problems solved by technology

Due to the large size, heavy weight and low output power of the combined power frequency X-ray machine head, the full-wave rectification is used, and the output X-rays are unstable, which affects the effect of the image.

The combined high-frequency and high-voltage X-ray head is small in size, light in weight, stable in output X-rays, and has good image effects. Most of the tubes in the combined high-frequency and high-voltage X-ray heads on the market are fixed anode type. Due to the defects of the fixed anode itself and the volume requirements, the output power is greatly limited. Generally, the output power is below 8KW. Although some manufacturers also use the combined head with a rotating anode tube, the structure is limited. According to the requirements of the process, the output power can only output 10KW. If the output is too high, it is easy to discharge and burn the device inside the high-pressure fuel tank.
