Principles of Conventional Radiography and Fluoroscopy
Veterinary Clinics of North America: Small Animal Practice, 1993Diagnostic radiology is an extremely valuable tool in the practice of veterinary medicine. Basic knowledge of primary exposure factors and their interrelationship are required to consistently produce quality radiographs. This article discusses basic radiation physics and radiation safety guidelines.

Sacral abnormalities—computed tomography versus conventional radiography
Journal of Computed Tomography, 1984Seventeen examples of different pathologic conditions, including malignant and benign tumors, and inflammatory, traumatic, and congenital lesions involving the sacrum, are presented. The value of computed tomography is compared with that of conventional methods with respect to diagnostic evaluation and clinical management of these patients.

Panoramic Versus Conventional Radiography of Scaphoid Fractures
American Journal of Roentgenology, 2004The objective of this study was to compare the diagnostic value of panoramic and conventional radiography in the detection of fractures of the carpal scaphoid bone.Panoramic (orthopantomographic) and conventional radiographs of 90 patients with acute or chronic wrist trauma were reviewed retrospectively.

Controversies in conventional radiography in spondyloarthritis
Best Practice & Research Clinical Rheumatology, 2012Radiographic assessment of spondyloarthritis constitutes the primary imaging modality for diagnostic evaluation although it is insensitive in early disease. Several years are required before definite changes can be seen in the sacroiliac joints, and magnetic resonance imaging is the preferred imaging modality when the clinical presentation suggests ...

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
