Description

Technical Field

[0001] The present application relates to the field of medical technology, and in particular to a comprehensive template for positioning light fields and ray fields and a control method thereof. Background Art

[0002] Currently, in breast X-ray machines, it is very difficult to adjust the light field and radiation field to match the irradiation range of different compressions. The different irradiation ranges of the light field need to be measured with a ruler, but the measurement results are inaccurate and there are no ready-made templates available on the market. Currently, other people in this field often use a coin or metal plate for positioning measurement. In order to standardize the relevant test content, a universal standard template suitable for breast X-ray machines has been developed.

[0003] Furthermore, the light and radiation fields are controlled by a beam limiter. X-rays are emitted from the tube's focal point and pass through the beam limiter to limit the range of the output radiation imaged on the flat panel. The light source of the light field is then directed to the receiving surface through a reflector and beam limiter, which must be consistent with the radiation field. Current control methods require that the distance from the light source to the receiving surface be the same as the distance from the tube's focal point to the receiving surface, and that they be coaxial, making this difficult to implement.
