Dimensional reproduction in rotational panoramic radiography
Oral Surgery, Oral Medicine, Oral Pathology, 1986The customary mathematical expressions for magnification in rotational panoramic radiography are examined. It is shown that although these expressions yield correct results for small objects placed perpendicularly to the central ray of the beam, they must be corrected in other situations.

Panoramic Radiography for Use in Experimental Dogs
Dentomaxillofacial Radiology, 1979The use of panoramic radiography in experimental dogs is described. The advantages of this technique as compared to conventional radiography of the maxillo-mandibular apparatus in experimental small animals are exemplified with radiographs of dental implants in beagles. The technical prerequisites and limitations of the technique in dogs are discussed.

Digital panoramic radiography: An overview [PDF]
Seminars in Orthodontics, 2004 New technologies are continually being developed and one of the most useful for clinical orthodontics is the development of the digital panoramic radiograph. This article describes this technology including what digital panoramic images are, how they are acquired, and some attributes and advantages of these newer methods. Advantages for the orthodontic

Panoramic radiography in orthodontic diagnosis
American Journal of Orthodontics, 1967Abstract Despite the great and continuing challenge of diagnosis and the need for constant evaluation of continuing orthodontic therapy, the emphasis until recently has been on the mechanisms of actual treatment and not on the all-important phase of diagnosis.

Influence of the rotation centre in panoramic radiography
Radiation Protection Dosimetry, 2007The aim is to present the curve of the rotation centre in dental panoramic radiography and to examine its influence on organ doses. A screenless film was fixed between the layers of an Alderson Rando phantom in the centre of the mandible. The phantom was positioned in two different X-ray units [Scanora (Soredex, Helsinki, Finland) and Orthophos (Sirona,

Dynamic focal plane estimation for dental panoramic radiography.
Medical Physics (Lancaster), 2019PURPOSE The digital panoramic radiography is widely used in dental clinics and provides the anatomical information of the intraoral structure along the predefined arc-shaped path. Since the intraoral structure varies depending on the patient, however, it

Rare earth screens for panoramic radiography
Oral Surgery, Oral Medicine, Oral Pathology, 1984Six panoramic radiographs, each made with a different screen/film combination, were compared for "periapical visibility" by fourteen dentists. Two combinations (a par-speed and a high-speed) used calcium tungstate screens, and three used rare earth screen systems four times faster than par-speed.
