When was digital radiography introduced?
1987
What is digital radiography used for?
Digital radiography (DR) is an advanced form of x-ray inspection which produces a digital radiographic image instantly on a computer. This technique uses x-ray sensitive plates to capture data during object examination, which is immediately transferred to a computer without the use of an intermediate cassette.
What are the advantages and disadvantages of digital radiography?
List of Pros of Digital Radiography
- It is faster to process and provides more options.
- It provides images with better quality.
- It requires less resources.
- It decreases the need for retakes.
- It is expensive initially.
- It may require constant replacement of equipment.
- It requires new knowledge and skills.
What is the difference between digital and computed radiography?
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 is Alara principle in radiography?
ALARA stands for “as low as reasonably achievable”. This principle means that even if it is a small dose, if receiving that dose has no direct benefit, you should try to avoid it. To do this, you can use three basic protective measures in radiation safety: time, distance, and shielding.
Can a radiographer read an MRI?
Depending on the part of your body being scanned, you’ll be moved into the scanner either head first or feet first. The MRI scanner is operated by a radiographer, who is trained in carrying out imaging investigations.
Is radiology the same as radiography?
Radiographers are the medical professionals tasked with operating highly specialized, state-of-the-art scanning machines. These health care professionals operate medical imaging equipment, while radiologists are primarily concerned with providing imaging interpretation.
Which is best radiology or radiography?
Some experts feel that B.Sc in Radiology degree is better as compared to B.Sc in Radiography in reference with certain aspects. But truly speaking, both these courses have a unique position in the field of medicine. These courses as well have a powerful role in various fields of application.
What are the different types of radiography?
The most common types of diagnostic radiology exams include:
- Computed tomography (CT), also known as a computerized axial tomography (CAT) scan, including CT angiography.
- Fluoroscopy, including upper GI and barium enema.
- Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA)
- Mammography.
What is the difference between medical imaging and radiography?
Medical imaging is a technology which is used by radiologists, particularly for diagnostic purposes. Although the word “radiology” sounds like it involves radiation, that is not always the case – for example, MRI (magnetic resonance imaging) and ultrasound do not use radiation in their medical imaging technologies.
How much do you make in radiography?
The U.S. Bureau of Labor Statistics reports that the average annual Radiology Technician salary is $57,450, with 50 percent of X-ray Technician positions paying between $46,490 and $70,430. The highest Radiographer salary — as reported in the top 10 percent of positions — comes in at $82,590.
