Beam limiting device and X-ray generating device.

Abstract

The invention provides a beam limiting device and an X-ray generating device. The beam limiting device comprises a bottom plate, a first shielding module, a main driving module, a driving power supplyand a control module. The first shielding module is arranged on the bottom plate and includes a first wire shielding plate and a second wire shielding plate. The main driving module includes a proportional electromagnetic valve and a transmission rod; and the transmission rod is connected between the first wire shielding plate and the proportional electromagnetic valve so as to drive the first wire shielding plate to move under the driving of the proportional electromagnetic valve. The driving power supply is connected with the proportional electromagnetic valve; and the control module is connected with the proportional electromagnetic valve and the driving power supply. According to the beam limiting device, transmission errors can be effectively reduced and the opening and closing control speed and precision of the wire shielding plate can be improved, so that the passing amount of X-rays is accurately controlled and harm to human health caused by redundant X-rays in the detection process is avoided. With the beam limiting device and the X-ray generating device, the irradiation range of X-rays can be accurately controlled, and the health of the detection personnel can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical diagnosis and treatment equipment, in particular to a beam limiter and an X-ray generating device. Background technique [0002] X-ray diagnostic technology is the earliest application of non-planing visceral inspection technology in the world. When X-rays pass through the human body, different parts have different absorption levels. For example, the amount of X-rays absorbed by bones is more than that absorbed by muscles. Carrying the density distribution information of various parts of the human body, there is a big difference in the strength of the fluorescent effect or photosensitive effect caused on the fluorescent screen or photographic film, so it will be displayed on the fluorescent screen or photographic film (after developing and fixing). Shadows of different densities. According to the comparison of shadow shades, combined with clinical manifestations, laboratory results and pathologi...

Problems solved by technology

In this structure, the control precision of the motor itself can reach a very high level, but a series of transmission errors make the opening and closing precision of the final shield far lower than the control precision of the motor, so that there are still redundant X-rays in the detection process Exposure to non-detection parts of the human body poses a threat to human health
