Abstract:
This study compared the radiation dosage necessary for obtaining clinically acceptable images with a new dental imaging system (radiovisiography) to that required with a conventional-film radiographic technique. Results showed that radiovisiography required significantly less radiation exposure, only 22.3% of that used in the conventional technique. Problems, such as lack of flexibility and the limited size of the x-ray-sensitive surface, are associated with radiovisiography; however, the system effectively complements conventional-film radiography.

X-ray Imaging
Computed Tomography
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...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Imaging Studies for Cardiovascular System III: X-Ray
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...
