Direct magnification radiography using conventional radiographic equipment
American Journal of Roentgenology, 1980Direct magnification radiography provides superior image quality with a resultant increase in diagnostic accuracy [1]. An x-ray tube with a nominal focal spot size of 0.1 mm is necessary for twofold or greater magnification [2]. Most recent reports on magnification radiography have used a 0.09 mm nominal focal spot x-ray tube consisting of an electron ...

Conventional Chest Radiography
1990Plain radiographs of the chest are obtained routinely with the patient in an erect position, with fully suspended respiration, preferentially at total lung capacity (1). The focal point-film distance should be at least 1.80 m. A high kilovoltage (kVp) technique should in general be applied, at least 120 kVp (2,3), preferably with an additional 0.3 to 0.

Conventional Radiography in TMJ Imaging
2018Conventional radiography includes simple projectional X-ray imaging along with panoramic radiography. All except panoramic radiography are obsolete, although the reverse Towne’s view may still be used for suspected mandibular trauma, and cephalograms, although not specifically TMJ radiography, are also used in assessment of some TMJ disorders.

Digital Radiography vs Conventional Radiography: Is Digital Radiography in Compliance With the Code?
Nondestructive Engineering: Applications, 2002Savannah River Technology Center filmless radiographic imaging system specialists have been “champions” of filmless radiographic imaging at the Savannah River Site since 1993. Recently a study was done comparing the differences between conventional film radiography and lens-coupled, charge-coupled-device digital radiography.

Phosphors for conventional and computed radiography
Nuclear Tracks and Radiation Measurements, 1993Abstract A way is suggested of solving problems of determination of optimal sensitivity in radiographic image visualization systems. Means for elaborating such systems for conventional radiography are considered, and these consist of combining intensifying screens with film, and for computed radiography, which is based on use of image storing screens.

Conventional Radiography and Tomography
2007Over the years there have been many attempts to visualise the SCC region by conventional radiography, but most have been unsuccessful. The osseous structures can be visualised by conventional tomography, but not to the extent obtained by CT or MRI, which in addition visualise the surrounding soft tissue structures. The conventional radiographic methods

Conventional Radiography of the Appendicular Skeleton
1989The objective of good orthodox radiography is to demonstrate the part under examination to its best advantage. Clearly, this often depends upon the reason for the examination being requested, but it is necessary in a busy department to undertake routine examinations in a standard way for reasons of time, expense, lack of clinical information and serial
