|December 1, 1981
Summary
Faster screen/film combinations, including rare earth screens, are effective for orthodontic cephalometric measurements. These advanced radiographic techniques provide adequate visualization for skull and jaw landmark identification and overall assessment.
Area of Science:
- Radiology
- Orthodontics
- Medical Imaging
Background:
- Cephalometric radiography is crucial for orthodontic diagnosis and treatment planning.
- Evaluating the impact of different screen/film combinations on radiographic quality is essential for optimizing diagnostic accuracy.
Purpose of the Study:
- To compare the usefulness of four different screen/film combinations for orthodontic cephalometric measurements.
- To assess the adequacy of radiographic images for landmark identification and overall diagnostic value.
Main Methods:
- Four lateral cephalometric radiographs were produced using varying screen/film combinations (speeds 1-4), with one using a grid and another rare earth phosphors.
- Seven orthodontists evaluated the radiographs, identifying eight specific landmarks and assessing overall image quality.
Main Results:
- No significant differences were found in landmark visualization or overall value among the tested screen/film combinations.
- All tested screen/film combinations were deemed adequate for orthodontic measurements.
Conclusions:
- Faster screen/film combinations, including those with rare earth screens, are both usable and useful for cephalometric radiography in orthodontics.
- The choice of screen/film combination does not significantly impact the diagnostic quality for orthodontic skull and jaw measurements.

01:24X-ray Imaging
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

01:20Imaging Studies for Cardiovascular System III: X-Ray
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
