While digital panoramic photography taken along travelling routes is very popular, digital panoramic strip maps are virtually nonexistent. In this article, we explore the characteristics of panoramic strip maps and provide an interactive method for their digital creation, focusing on the challenge of straightening curved routes. The resulting software Terrain Bender implements a geometric defor...
Understand the limitations of panoramic radiography in detecting systemic diseases. For the purposes of this report, “systemic disease” will be interpreted as conditions that are spread out within the body rather than localized strictly to the tissues of the oral cavity. Since it would take many volumes to review all such conditions, the intent of this issue of Panoramic Imaging News is to revi...
PURPOSE Panoramic radiographs taken using conventional chin-support devices have often presented problems with positioning accuracy and reproducibility. The aim of this report was to propose a new bite block for panoramic radiographs of anterior edentulous patients that better addresses these two issues. MATERIALS AND METHODS A new panoramic radiography bite block similar to the bite block fo...
background and aims. panoramic radiographs are used for surgical planning of unerupted third molars. the major problems associated with panoramic radiography include unequal magnification and geometric distortion of the image. the purpose of this study was the clinical evaluation of the effect of radiographic distortion on the position and classification of unerpted mandibular third molars. mat...
to report the association of pulp calcification with that of cardiovascular disease (cvd) using digital panoramic dental radiographs.digital panoramic radiographs of patients referred from the angiography department were included if the patient was under 55 years old and had non-restored or minimally restored molars and canines. an oral and maxillofacial radiologist evaluated the images for pul...
Creating of panoramic images is a common technique nowadays. The needed components are a sequence of overlapping digital images and a suitable stitching software. There are several software available for combining single images together just by few mouse clicks. They can also take care of the image distortions and adjust the radiometric differences so that the final image looks very consistent....
PURPOSE This study compared the SCGAs measured in three types of radiographic images (panoramic, CBCT panoramic-section, and CBCT cross-section images) with values measured using the protrusive occlusal record. MATERIALS AND METHODS SCGAs were measured in 20 patients on a semi-adjustable articulator using the protrusive interocclusal record. Panoramic and CBCT images were obtained. SCGAs were...
Background and Aims: The Panoramic radiography is one of the routine techniques in implant imaging. Although there are some limitations with this technique, panoramic radiography is radiographic choice for basic evaluation for implant treatment. Many studies have been designed to determine magnification in panoramic images but most of them were performed on dry skulls or radiographic phantoms. ...
In this paper, we review design and principles of existing panoramic cameras. Panoramic cameras which enable 3D computation in reasonable time for real time applications are emphasized. We classify panoramic cameras w.r.t. their construction, field of view, and existence of a single projective center. Using this classification we state a utility of the central catadioptric panoramic cameras. We...
