What is radiology technique?
*Radiography (or X-ray picture) is a type of radiological imaging technique which applies X-radiation. As a result of radiography, we receive images called radiographs. This imaging techniques is designed to identify abnormalities or lesions in the human body. Radiography is performed using X-ray machine.
What is a radiograph technique chart?
Technique charts are tables that contain settings for selection on the x-ray control for a specific anatomical part. These factors control the amount of radiation delivered to the patient and to the film.
What is a radiograph used for?
It is used to diagnose or treat patients by recording images of the internal structure of the body to assess the presence or absence of disease, foreign objects, and structural damage or anomaly. During a radiographic procedure, an x-ray beam is passed through the body.
What is the difference between radiology and radiography?
And, while each career path deals with issues regarding patient diagnostics and testing, radiologists are generally doctors trained to read and interpret imaging scans, while radiographers are medical technicians who perform diagnostics imaging tests. Radiologists usually do not perform the imaging tests.
What is the difference between kVp and mAs?
* kVp: the power and strength of the x-ray beam (quality of the x-rays). * mAs: the number of x-ray photons produced by the x-ray tube at the setting selected (quantity of x-rays). * time: how long the exposure lasts. kVp stands for kilovoltage peak.
Why is a technique chart important?
A technique chart provides a consistent method of choosing the proper radiograph settings without having to calculate all of the components by hand with each exposure. Taking the time to prepare a technique chart in the beginning will help to save time, money, and radiation exposure to both the patient and staff.
What are the imaging techniques used in projection radiography?
Aside from the sectional imaging techniques of ultrasonography, computed tomography (CT), and magnetic resonance (MR) imaging, digital imaging systems are also employed with increasing frequency in projection radiography.
What is the best radiography for the musculoskeletal system?
Given its many advantages, digital luminescence radiography with storage screens is currently the favored imaging procedure in projection radiography of the musculoskeletal system. K2 systems with an image matrix of 2048×2048 are used for diagnosis of the hand.
Why is it called Direct radiography?
Since an intermediate step of optical, electronic, or mechanical scanning is unnecessary, this technology is referred to as direct radiography. Direct radiography has superior quantum efficiency to other imaging systems, resulting in lower image noise at the same radiation dose.
What is projection radiography with electronic flat detectors?
In addition to the phosphorus storage-screen technique, projection radiography with electronic flat detectors (semiconductors and flat-panel detectors) provides a further digital procedure for projection radiography. These systems employ either amorphous silicon or selenium as the detector.
