Xray - Week 3 PP Flashcards
Who discovered x-radiation?
Wilhelm Conrad Roentgen, a Bavarian physicist, discovered the X -ray on November 8, 1895
For many years x-rays were referred to as roentgen rays, radiology was referred to as
roentgenology, and radiographs were known as roentgenographs
First radiograph of the human body?
Roentgen placed his wife’s hand on a
photographic plate and exposed her to the rays for 15 minutes to show
that he could capture the outline of her bones permanently.
Otto Walkhoff
produced the first recorded dental
radiograph by exposing a photographic plate in his mouth for 25 minutes in
Dr. C. Edmund Kells
a New Orleans dentist, is credited with the first practical use of radiographs in dentistry, in 1896 Kells, after years of exposing his hands to X-rays every day, eventually lost his fingers, hand, and later his arm as a result of cancerous tumors.
Year of the first intraoral imaging sensor?
1987
An article describing direct digital imaging technology published in U.S. dental literature - what year??
1989
Cone-beam computed tomography was
introduced to dentistry in what year? What does it do?
Cone-beam computed tomography was
introduced to dentistry in 1999; allows for the viewing of oral structures in three dimensions - allows for the diagnosis of disease and image guidance of surgical procedures
Oral and Maxillofacial Radiology (OMFR)
In 1999, the American Dental Association (ADA) recognized its ninth specialty program: Oral and Maxillofacial Radiology (OMFR)
◦ Provides advanced training in radiology of
the oral and maxillofacial region
◦ 2 to 3-year residency term after completion of dental school, followed by an
international board examination
Radiograph
- a picture (a visible photographic record) on film produced by the passage of X-rays through an object or body; also called X-ray film.
- In practice, often called an “x-ray”; this is not correct. X-ray (also x-ray) is a term that refers to a beam of energy
Dental radiograph
- A photographic image produced on film by the passage of X-rays through teeth and related structures
Radiography
- The art and science of making radiographs by the exposure of the film to X-rays
Dental radiography
- The production of radiographs of the teeth and adjacent structures by the exposure of the film to Xrays
Dental radiographer
- Any person who positions, exposes, and processes X-ray film
Image
- A picture or likeness of an object
Image receptor
- A recording medium; examples include x-ray film, phosphor plate, or digital sensor
