Which term describes the part of the body closest to the film during a radiographic exposure?
The term is "anatomic landmark." It refers to specific structures in the body that radiologists use as reference points when viewing radiographic images.
What is the radiographic equivalence for titanium for selenium source?
The radiographic equivalence for titanium when using a selenium source is typically around 0.30 to 0.35. This means that titanium has a similar radiographic density to materials that would require a selenium source for adequate imaging. The specific equivalence can vary based on factors like the thickness of the titanium and the energy of the radiation used. Thus, understanding these parameters is crucial for accurate radiographic assessments.
Radiographic study involving the urinary system is?
Intravenous pyelogram (IVP) is a radiographic study involving the urinary system. It uses a contrast material injected into a vein to visualize the kidneys, ureters, and bladder on X-ray images. IVP is primarily used to evaluate the structure and function of the urinary system.
What is the medical term meaning radiographic examination of the lymphatic vessels after the injection of a contrast medium?
The medical term you are looking for is lymphangiography. It involves using a contrast medium and radiographic imaging to visualize the lymphatic vessels.
Which radiographic study is also known as a flat-plate of the abdomen?
KUB(Kidneys,Ureters,Bladder)
What is the device that holds radiographic film?
cassette
What are the sizes of the radiographic film?
10x12cm 24x30cm 30x40cm 34x43cm
What kind of radiographic film is used for apical pathology?
Periapical Radiographs
Which radiographic projection has the patient positioned with the back parallel to the film?
anteroposterior
What type of radiographic projection has the patient positioned facing the film and parallel to it?
A PA film has the patient facing and parallel to the film.
What layer of a typical radiographic film has sensitizing dyes that tailor the response characteristics of a given film?
phosphor
What is the density of an unexposed processed radiographic film?
between 0.12 and 0.20. As the film gets older the density will get higher. There is a standard out there that limits the usable film "base fog" density to 0.30.
What is meant by the term - 'reticulation of radiographic film'?
Reticulation of radiographic film refers to a pattern of fine lines or a mottled appearance that can occur on the film due to improper processing. This phenomenon is often caused by extreme temperature changes during the developing process, particularly when the film is rapidly cooled or heated. It can compromise the quality of the radiographic image, making it difficult to interpret. Proper temperature control and processing techniques are essential to avoid reticulation.
Which radiographic projection has the patient positioned so the body is slanted sideways to the film?
oblique
Comperism between geometric unsharpnes and radiographic unsharpness?
geometric unsharpness is fixed by setting the focal radius,etc. while radiographic unsharpness consists of both geometric and film unsharpness.
What is the relationship between film screen speed and radiographic density?
As film screen speed increases, radiographic density decreases. Faster film screens require less exposure to produce the same density as slower film screens. This relationship is important in balancing exposure settings to achieve optimal image quality.
Which term describes the part of the body closest to the film during a radiographic exposure?
The term is "anatomic landmark." It refers to specific structures in the body that radiologists use as reference points when viewing radiographic images.
