Schuller's view is a lateral radiographic view of skull principally used for viewing mastoid cells. [1] The central beam of X-rays passes from one side of the head and is at an angle of 25° caudad to the radiographic plate. This angulation prevents overlap of images of the two mastoid bones. The radiograph for each mastoid is taken separately.
Waters' view (also known as the occipitomental view or parietoacanthial projection) is a radiographic view of the skull. It is commonly used to get a better view of the maxillary sinuses. An x-ray beam is angled at 45° to the orbitomeatal line. The rays pass from behind the head and are perpendicular to the radiographic plate.
In 1909, Charles A. Clark described a radiographic procedure for localizing impacted teeth to determining their relative antero-posterior position. [1] If the two teeth (or, by extension, any two objects, such as a tooth and a foreign object) are located in front of one another relative to the x-ray beam, they will appear superimposed on one another on a dental radiograph, but it will be ...
The standard abdominal X-ray protocol is usually a single anteroposterior projection in supine position. [3] Special projections include a PA prone, lateral decubitus, upright AP, and lateral cross-table (with the patient supine).
Like all methods of radiography, chest radiography employs ionizing radiation in the form of X-rays to generate images of the chest. The mean radiation dose to an adult from a chest radiograph is around 0.02 mSv (2 mrem ) for a front view (PA, or posteroanterior) and 0.08 mSv (8 mrem) for a side view (LL, or latero-lateral). [ 1 ]
There are also available markers to indicate positioning of the body e.g. supine, or as to time when performing procedures such as an Intravenous pyelogram. It has been suggested that radiographic markers are a potential fomite for harmful bacteria such as MRSA, and that they should be cleaned on a regular basis; this, however, is not always ...
Fish bone pierced in the upper esophagus. Right image without contrast medium, left image during swallowing with contrast medium. To obtain an image with any type of image detector the part of the patient to be X-rayed is placed between the X-ray source and the image receptor to produce a shadow of the internal structure of that particular part of the body.
Human chest radiographic anatomy. Radioanatomy ( x-ray anatomy ) is an anatomy discipline that involves studying anatomy through the use of radiographic films . [ 3 ] The x-ray film represents a two-dimensional image of a three-dimensional object due to the summary projection of different anatomical structures onto a planar surface.
