What is the 15 rule in radiography?
The 15% rule states that changing the kVp by 15% has the same effect as doubling the mAs, or reducing the mAs by 50%; for example, increasing the kVp from 82 to 94 (15%) produces the same exposure to the IR as increasing the mAs from 10 to 20. A 15% increase in kVp has the same effect as doubling the mAs.
What are the two types of radiography?
There are two kinds of radiography: Diagnostic radiography, which is the use of radiation to investigate a patient’s illness or injury, and: Therapeutic radiography, which is the use of various kinds of radiation to treat an illness or injury.
What is kVp in radiography?
kVp stands for kilovoltage peak. 116,117. This is the highest voltage (measured in thousands of volts) that will be produced by the x-ray machine during an exposure. For example, if 60 kVp is selected, 60 kilovolts (60,000 volts) is the maximum strength of x-rays produced in this exposure.
What does R mean in xray?
So, what is it? Each lead marker is identified with an ‘R’ that represents right or an ‘L’ that represents left. They are also identified with the radiologic technologist’s initials. Every radiologic technologist places one of these lead markers on all images.
What is a radiograph vs xray?
Non-imaging clinicians and the lay population generally use the term “x-ray” to refer to a radiograph, as well as for the radiation itself; e.g. a chest radiograph is often referred to as a chest x-ray. Radiograph is not used to describe dynamic images, which are usually referred to as fluoroscopic images.
What makes a good radiographer?
excellent interpersonal and communication skills in order to explain procedures to patients. a supportive and caring disposition. good observation skills and attention to detail. self-motivation and the ability to work under pressure.
What does a radiographer do?
Radiography is the use of radiation to treat injured and ill patients. Radiographers also aid in the diagnosis of patients through capturing images of bones, organs and human tissue. They are specially trained to use imaging equipment to assist other medical professionals when treating patients.
What is tube voltage?
A high voltage power source, for example 30 to 150 kilovolts (kV), called the tube voltage, is connected across cathode and anode to accelerate the electrons. The X-ray spectrum depends on the anode material and the accelerating voltage.
How to learn Radiology from a radiologist?
– Spend as much as time in your department as possible and get to know your colleagues and seniors. – Treat your seniors and colleagues with respect. – Develop a good rapport with your technicians. – Be responsible. – Try to make your own presentations for inter-department rounds rather than copy-pasting it from other sources.
Why you should do diagnostic radiology?
– You at least like diagnostic radiology. DR is the foundation of IR and it’s a critical part of IR training. – You love engineering, bio-tech, shiny tools, and machines. – You need variety, procedures, and cerebral problem solving. – You are okay with working near-surgery hours and enjoy patient interaction

Why Radiology is the eye of Science?
This explains, for example, why it is possible to detect foreign material such as projectiles within bone using radiology—bullet lead attenuates more x-rays (i.e., appears more radiopaque) than bone, making it appear distinct from bone (which attenuates more x-rays than soft tissues but less than lead) in a radiologic image.
