What does dr mean?

Dr (Digital Imaging Technology) generally refers to digital X-ray photography. Digital Radiography (DR) is also a new digital imaging technology recently developed, which has similar uses to Computer Radiography (CR), but its basic principle and structure are different. DR is developed on the basis of digital fluorescence photography (DF). It takes the image intensifier tube as the information carrier, receives the X-ray information transmitted through the human body, converts it into digital signals after being collected by the camera, and then carries out digital processing.

Different from CR, except the information carrier, it is not matched with other equipment and needs special equipment. CR can collect information through the imaging board on any X-ray imaging equipment. DR, like CR, can do post-processing of many kinds of images, and can transmit and store images.

Advantages of digital X-ray photography

The radiation dose is only 20% of the traditional dental film, which is very beneficial to both doctors and patients and the protection of oral diagnosis and treatment environment. Fast imaging, fast imaging on the display or printer output after exposure, without interfering with the disease treatment process; Based on computer technology, digital image has many image processing capabilities, such as magnification, inversion and edge enhancement, which is helpful for the diagnosis of a specific imported disease. Digital imaging digitizes signals, which can be quantitatively analyzed, so that some diseases can be dynamically observed.

In the optical experiment, digital imaging technology also has the advantages of enhancing the intuition of the experiment, maximizing the clarity and repeatability of the image, and reducing the return error of the experiment.
