What is CR mammography?
What is CR mammography?
CR mammography uses a phosphor-based plate which is “read” by a special mammo CR and then digitized into a computer. Think of the plate as the card that comes out of your camera and has to be plugged into the computer to be shared and looked at.
What is the function of the CR reader?
Replacing the traditional chemical developer is a digital computed radiography reader. The basic function of the reader is to remove and scan the phosphor plate from the cassette. The majority of CR readers also erase and reinsert the plate into the cassette at the end of the process.
What is CR reader in radiography?
Computed radiography (CR) is the use of photostimulable phosphor as an image receptor. The image receptor is held in a similar casing (cassette) to that of the traditional film screen.
What is CC and MLO views mammography?
Standard Digital Mammogram Images. There are two standard views of the breast taken during mammography. Craniocaudal, or “CC view” (taken from top-down, shown on left), and mediolateral oblique, or “MLO view” (taken from the side at an angle, shown on right).
What is the technical name for a CR imaging plate?
What is the technical name for a CR imaging plate? Photostimulable phosphor plate.
What are the three basic steps in creation of CR image?
Like other DR technologies, the basic CR imaging cycle has three steps: (a) expose, (b) read out, and (c) erase, or reinitialize (Fig 7). Referring to Figure 7, in the exposure step, x rays are absorbed within the active layer, which creates a stored latent image of trapped electrons within the phosphor particles.
What is difference between CR and DR?
DR uses flat panel detectors based on direct or indirect conversion of X-rays to charge, which is then processed to produce a digital image. CR uses cassette-based phosphor storage plates (PSP), which are then scanned by the computerized system into a digital format for image processing, archiving, and presentation.
How often should CR plates be erased?
Too frequent cleaning of the phosphor screens can discolor the phosphor. The imaging plate that have not been used for more than 24 hours should be erased before use.
What is the difference between DR and CR?
What is a CR study?
CR tests all types of dental products, including materials, devices, and equipment, plus techniques. Worldwide, products are purchased from distributors, secured from companies, and sent to CR by clinicians, inventors, and patients. There is no charge to companies for product evaluations.
