What is computed radiography system?

This device is an image digitization system designed to acquire and digitize x-ray images from image storage phosphor plates. A CR system consists of an image reader/digitizer, cassettes containing imaging receptors (photostimulable-phosphor plates), a computer console or workstation, software, monitors, and a printer.

How do CR systems work?

In computed radiography, when imaging plates are exposed to X-rays or gamma rays, the energy of the incoming radiation is stored in a special phosphor layer. A specialized machine known as a scanner is then used to read out the latent image from the plate by stimulating it with a very finely focused laser beam.

What is the difference between CR and DR system?

Both are types of digital x ray equipment but what is the difference between CR and DR radiography? Digital Radiography (DR) is the latest advancement in Radiography. Computed Radiology (CR) is the digital replacement of X-ray film radiography. CR radiography uses phosphor image plates to create a digital image.

What is the difference between computed and digital radiography?

Computed radiography is an indirect process, designed to be a replacement for traditional film radiography. Digital radiography uses a digital detector array, also known as a flat panel detector in place of an IP or traditional film.

What is the PACS system in radiology?

PACS (picture archiving and communication system) is a medical imaging technology used primarily in healthcare organizations to securely store and digitally transmit electronic images and clinically-relevant reports.

What are the advantages of computed radiography?

Advantages of computed radiography compared with conventional film/screen combinations include improved contrast resolution and postprocessing capabilities. Computed radiography’s spatial resolution is inferior to conventional radiography; however, this limitation is considered clinically insignificant.

What is the difference between PACS and Dicom?

PACS provide storage and convenient access to medical images such as ultrasounds, MRIs, CTs, and x-rays. DICOM is both a protocol for transmitting images and a file format for storing them.

What are the advantages and disadvantages of computed radiography?

Both computed radiography (CR) and digital radiography (DR) require the use of digital technologies which rely on computer networks and high-bandwidth web facilities….Disadvantages for DR.

CR DR
Higher risk of overexposure Lower risk of overexposure
Suitable for low or moderate workflow Ideal for high workflow
