Digital and Computed Radiography systems each offer different advantages and disadvantages over each other. Many actually consider digital radiography X-Ray systems as the next step from computed radiography system owing to the greater safety and image quality advantages that these have to offer. As someone considering adding an X-ray system to their practice, it’s important to note how either can contribute to the office before deciding which type they prefer.
To help make the decision, we’ve conducted an assessment of both types of radiography systems based on key factors that determine overall organizational efficacy and efficiency.
Differences In Mechanism
Computed radiography uses analog imaging mechanisms to take X-ray exposures with computed radiography cassettes that have to be inserted and removed to acquire x-ray images. These are then transferred onto a screen output to present the medical imaging as required by a physician. This makes the imaging process tedious and time consuming.
Digital radiography equipment, on the other hand, does not rely on any analog imaging mechanisms at all. DR uses digital X-ray detectors to help capture and render images on a screen to present an x-ray for diagnosis, assessment and treatments.
Image Quality
A DR system is superior to a CR system with regard to image quality and imaging modalities. These can work at multiple resolutions and enhance the image output compared with what you would get with CR equipment. In addition to this, a digital radiography system can be programmed to work on different modalities to allow for better diagnosis and imaging results.
A CR system does not offer as much versatility and image clarity compared to DR systems. The transfer process from the tapes to digital output doesn’t allow for much manipulation and changes in modalities that a DR system would provide. In terms of picture quality there is no competition between a DR and a CR.
Radiation Exposure
Patient protection is of utmost importance when conducting radiographic assessments. Radiation exposure is a major health concern for patients and doctors need to be very careful when recommending the screening to ensure that the patient will not be harmed from the screening. DR imaging reduces the amount of radiation exposure to the patient and is safer than CR imaging.
DR Systems Are Wireless
DR systems are much more compact in their design and do not require as much hardware as compared to a CR system. This saves space and helps for faster workflow as well as increased efficiency.
