High-resolution test cards (line-to-line x-ray) and second-degree cards (two dosage cards, chorus cards) are the resolution devices of x-ray devices used by hospitals, cdcs and third-party detection units to detect visual imaging equipment such as x-ray machines。
High-resolution test cards (line-to-card for x-ray detection) and second-degree cards (two-degree cards, chorus cards) are easy to use and simple operations are ideal detection tools. However, as the resolution detection requirements for the rays are increasing, so are the resolution requirements for the line to the card. There is currently no mature domestic line-to-line card to meet market demand. The line-to-check cards used in the market are mostly imported from abroad。
