In conventional radiography,
high image contrast
(a large difference between grey shades) is inevitably associated with a narrow latitude (a low number of grey steps). With digital radiographs, it is possible to display an image with a wide latitude, while preserving high image contrast.
What are the advantages of conventional radiography?
Compared with computed tomography (CT) and magnetic resonance imaging (MRI), it has the advantage of a higher spatial resolution, is inexpensive, easy to use, and widely available. Conventional radiography can
give high quality results if the technique selected is proper and adequate
.
What is conventional radiography?
Conventional radiography
involves the use of x-rays
; the term “plain x-rays” is sometimes used to distinguish x-rays used alone from x-rays combined with other techniques (eg, CT).
What are three advantages of digital radiography?
- reduced time,
- reduced radiation,
- ability to take multiple exposures without repositioning the sensor,
- storage and maintenance of the images,
- and electronic transmission of images.
What are the types of radiography?
- Radiography.
- Computed Tomography (CT)
- Dental Cone-beam Computed Tomography.
- Fluoroscopy.
- Mammography.
What is the limitation of conventional radiography?
Physics of Computed Tomography Scanning
Conventional radiography projects a three-dimensional object onto a two-dimensional image. The major limitation is that
different overlaying tissues are superimposed on the image
.
What is the primary advantage in using digital radiography?
Digital Radiography Advantages:
Greater Image Versatility
Along with the elimination of chemical processing, the digital format allows greater imaging versatility and overall image quality, both of which greatly increase the accuracy of patient diagnosis and the quality of care that can be provided.
How is digital radiography used?
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?
- 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 a disadvantage of using digital radiography?
The main disadvantages of direct digital radiography are
the thickness and rigidity of the digital detector, infection control, hardware and software maintenance
, and the higher initial cost of the system.
What are the advantages of radiography testing?
There are many advantages to radiography, including:
Inspection capability for many types of material with varying density
.
Ability to inspect assembled components
.
Minimal surface preparation required
.
What are the three basic rules of radiography?
Three basic principles should be adhered to when dealing with radiation and making radiographs:
• Time • Distance • Shielding
. These principles form the basis of a broader radiation safety concept called aLaRa (as Low as Reasonably achievable).
Is a radiographer a doctor?
Clinical radiologists are
doctors
who use images to diagnose, treat and manage medical conditions and diseases.
What is a radiographer salary?
This person performs diagnostic imaging examinations such as x-rays and computed tomography (CT) imaging on patients. As a newly certified radiographer, your starting salary is likely to
be $42,000
, rising up the pay scale to $61,000 with time and experience.
What do you know about radiography?
Radiography is
a health care science occupation dealing with medical diagnostic images
. It is one of the rapidly growing occupations in modern health care. … During training, students are exposed to all facets of health care. Training takes place at primary, secondary and tertiary institutions.
Which process can be done by CR?
Computed radiography
(CR) is the digital replacement of conventional X-ray film radiography and offers enormous advantages for inspection tasks – the use of consumables is virtually eliminated and the time to produce an image is drastically shortened.
