1. Overview The Canon Digital Radiography CXDI-50G is a portable X-ray digital camera that can take images of any part of the body. It directly converts the X-ray images captured by the LANMIT (Large Area New MIS Sensor and TFT) sensor into a high-resolution digital images.
2. Notes for Using the Instrument Handling Handle the instrument carefully, as it may be damaged if something is hit against it, dropped, or receives a strong jolt. Also, handle the optional grid unit with care too. Do not pull the cable. Also, do not pull the sensor unit when the cable is tangled with something.
