Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an automatic centering and tracking device for an optical beam emitter and a flat panel box. Background Art

[0002] X-rays are electromagnetic waves with very short wavelengths, produced when accelerated electrons collide with a metal target. During this collision, the electrons suddenly decelerate, and the lost kinetic energy is released as photons, forming a continuous portion of the X-ray spectrum, also known as bremsstrahlung. X-ray machines are primarily used in the medical field for diagnostic purposes. Common X-ray examinations include chest radiographs, cervical spine, thoracic spine, lumbar spine, and limbs, and are common and important medical devices. During clinical use of X-ray machines, technicians must position the body, ensuring that the beam guide and flat panel cassette are aligned horizontally. For subjects of varying heights, the beam guide and flat panel cassette must be aligned horizontally to ensure they match. Only when aligned horizontally can images be captured that meet clinical diagnostic criteria.

[0003] Currently, for similar X-ray machines on the market, the centering operation of the beam splitter and the flat-panel box is mainly done manually by pushing and pulling the beam splitter and the flat-panel box respectively. Clinically, the operation is cumbersome, time-consuming and labor-intensive. In addition, the manual centering effect is poor, and unqualified images are easily taken. The technicians have a heavy workload and low efficiency. Utility Model Content
