Computed radiography (CR) cassettes use photo-stimulated luminescence screens to capture the X-ray image, instead of traditional X-ray film. Digital radiography (DR) systems use active matrix flat panels consisting of a detection layer deposited over an active matrix array of thin film transistors and photodiodes.
What are DR systems?
DR Systems, Inc. provides healthcare imaging and information management systems. The Company offers dictation, speech recognition, transcription, advanced image processing, internet image, and results distribution systems. DR Systems serves customers in the United States.
What is DR imaging system?
Digital radiography (DR) is the direct conversion of transmitted X-ray photons into a digital image using an array of solid-state detectors such as amorphous selenium or silicon, with computer processing and display of the image.
What is CR system Radiology?
Computed Radiography — or CR for short — is the use of a Phosphor Imaging Plate to create a digital image. CR uses a cassette based system like analog film and is more commonly considered to be a bridge between classical radiography and the increasingly popular fully digital methods.

What is a DR detector?
Digital Radiography (or DR) is a form of x-ray imaging that utilizes digital x-ray sensing technology instead of conventional x-ray which uses film. The detector itself is based on amorphous silicon photodiode technology. These panels convert x-rays to light and then to an electrical charge.Sep 6, 2018
What is a DR panel?
Digital radiography (DR) systems use active matrix flat panels consisting of a detection layer deposited over an active matrix array of thin film transistors and photodiodes. With DR the image is converted to digital data in real-time and is available for review within seconds.
What are the 3 types of X-rays?
- X-ray (Radiography) There are three types of diagnostic radiographs taken in today's dental offices -- periapical (also known as intraoral or wall-mounted), panoramic, and cephalometric.

What are the two types of X ray machines?
There are many types - or modalities - of medical imaging procedures, each of which uses different technologies and techniques. Computed tomography (CTComputed tomography (CTThe carat (ct) is a unit of mass equal to 200 mg (0.00705 oz) or 0.00643 troy oz, and is used for measuring gemstones and pearls.https://en.wikipedia.org › wiki › Carat_(mass)Carat (mass) - Wikipedia), fluoroscopy, and radiography ("conventional X-ray" including mammography) all use ionizing radiation to generate images of the body.
What are the 3 most common x-ray views?
The most common views are posteroanterior, anteroposterior, and lateral. In a posteroanterior (PA) view, the x-ray source is positioned so that the x-ray beam enters through the posterior (back) aspect of the chest and exits out of the anterior (front) aspect, where the beam is detected.
