Exposure In Radiology
What is An Exposure In Radiology? Exposure is the amount of ionization produced in air when ionizing radiation is present. The air at the surface of an x-ray room tabletop or the interior of a computed tomography (CT) scanner becomes ionized when the x-ray tube...
Clinical Responsibilities Of Radiographer
What Are The Clinical Responsibilities Of Radiographer ? The clinical responsibility of radiographer encompass a wide range of tasks, including patient care, imaging procedure performance, and collaboration with other healthcare professionals. Below are the...
Film Hanger
What Is A Film Hanger? A film hanger is a device used in traditional radiography, particularly in the development process of X-ray films. When X-ray films are exposed to radiation during imaging procedures, they need to be developed to reveal the images...
mA Vs mAs
mA Vs mAs mA Vs mAs are two important parameters used in radiography, specifically in the field of X-ray imaging. mA stands for milliamperes and refers to the current used to generate X-rays in the X-ray tube. Increasing the mA setting will result in an...
Radiation
What Is Radiation? Radiation is the energy that travels through space or matter in the form of particle or wave. It involves transfer of energy from one place to another. It can also be seen as a form of energy given off by matter in the form of rays or high speed...
Fog In Radiographic Film
What Is Fog In Radiographic Film ? Fog in radiographic film is a term used to describe the appearance of radiograph (x-ray image ) that has a hazy or diffuse appearance, rather than being sharp and clear. The fog is grayness of film of varying grades from grey colour...
Fluoroscopy
What is fluoroscopy? Fluoroscopy is a medical imaging technique that uses X-rays to obtain real-time moving images of the internal structures of the body. During a fluoroscopy procedure, an X-ray beam is passed through the body. The image is transmitted to a...
X-ray
what Is An X-ray? X-rays are a type of electromagnetic radiation with wavelengths shorter and higher energies. They were discovered by Wilhelm Conrad Roentgen in 8 NOV 1895. X-rays are produced when high-energy electrons collide with a target material, causing the...
Filters
What Is A Filters In X-ray? The filter is a metallic sheet which position in the path of x-ray. The process of removing the low energy of x-ray by the help of metallic sheet is called filtration. The x-ray is a heterogeneous photons. The low energy photons make...
Bucky In Radiography
What Is Bucky In Radiography? Bucky In Radiography, A Bucky is a component of x-ray units that holds the x-ray film cassette and moves the grid during x-ray exposure. The motion keeps the lead strips from being seen on the x-ray picture. The name refers to Dr. Gustave...
