A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw.It shows a two-dimensional view of a half-circle from ear to ear. Panoramic radiography is a form of focal plane tomography; thus, images of multiple planes are taken to make up the composite panoramic image, where the maxilla and mandible are in the focal trough and the structures that are superficial and ...
A panoramic film, able to show a greater field of view, including the heads and necks of the mandibular condyles, the coronoid processes of the mandible, as well as the nasal cavity and the maxillary sinuses. Panoramic X-ray radiography of the teeth of a 64-year-old male shows dental work performed mostly in UK/Europe in last half of 20th century
The company was started in 1964 as Palomex Oy to manufacture the Orthopantomograph®, a device for making panoramic radiographs invented by Finnish professor Yrjö Paatero. The device made possible to take a panoramic X-ray dental image in a single exposure.
Focal plane tomography generally uses mechanical movement of an X-ray source and film in unison to generate a tomogram using the principles of projective geometry. [4] Synchronizing the movement of the radiation source and detector which are situated in the opposite direction from each other causes structures which are not in the focal plane ...
Taking an X-ray image with early Crookes tube apparatus, late 1800s. Radiography's origins and fluoroscopy's origins can both be traced to 8 November 1895, when German physics professor Wilhelm Conrad Röntgen discovered the X-ray and noted that, while it could pass through human tissue, it could not pass through bone or metal.

Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...
