What is the difference between CR and DR?

CR (Computerized X–ray Imaging (CR)) generally refers to computer radiography. Computer radiography refers to an X–ray projection imaging method that uses light to excite a storage phosphor as a detector, and also refers to a medical imaging device that uses such an imaging method.
DR refers to a new technology for digital X–ray photography directly under computer control. The amorphous silicon flat panel detector converts the X–ray information that penetrates the human body into a digital signal, and reconstructs the image and performs a series of images by computer. Post processing.

The DR system mainly consists of an X–ray generator, a direct conversion flat panel detector, a system controller, an image monitor, and an image processing workstation. Due to the use of digital technology, DR can perform various image post-processing according to clinical needs, such as image automatic processing technology, edge enhancement and clear technology, zooming roaming, image stitching, window width adjustment of interest area, distance, area, density measurement, etc. Rich features.
