The CR MD4.0 General Cassettes are user-friendly and durable CR
(computed radiography) cassettes with a memory chip for storing the
data entered at the ID terminal. The cassettes are compatible with
your existing X-ray tables, so there’s no need to modify your
exposure equipment and routines when switching from conventional to
digital imaging. With the embedded memory chip, the identification
data and the image are permanently linked as they pass through the
electronic processing system.
