radiograph

 [ra´de-o-graf″]
an image or record produced on exposed or processed film by radiography.
Relative positions of x-ray tube, patient, and film necessary to make the radiograph shown. Bones tend to stop diagnostic x-rays, but soft tissue does not. This results in the light and dark regions that form the image. From Thompson et al., 1994.
bite-wing radiograph a type of dental radiograph that reveals the crowns, necks, and coronal thirds of the roots of both the upper and lower posterior teeth, as well as the dental arches, produced using bite-wing film.
cephalometric radiograph a radiograph of the head, including the mandible, in full lateral view; used to make measurements; called also cephalogram.
flat plate radiograph a radiograph that visualizes abdominal organs and some abnormalities. It is usually one of the first diagnostic studies performed in assessing a patient for gastrointestinal disorders; no special physical preparation of the patient is necessary.
panoramic radiograph a type of extraoral body-section radiograph on which the entire maxilla or mandible can be depicted on a single film.

radiograph(s) (rā´dēōgraf),

n an image or picture produced on a radiation-sensitive film emulsion by exposure to ionizing radiation directed through an area, region, or sub-stance of interest, followed by chemical processing of the film. It basically depends on the differential absorption of radiation directed through heterogeneous media. See also x-ray.
radiograph, bite-wing (BWX),
n a form of dental radiograph that reveals approximately the coronal halves of the maxillary and mandibular teeth and portions of the interdental alveolar septa on the same film. Bite-wings can be used at any point in the dental arch. Older term:
x-ray.

Bite-wing radiograph.
radiograph, body-section,
n radiograph produced by rotation of the film and roentgen ray source around the region of interest in opposite directions during exposure, so as to blur interposed anatomic structures outside the region of interest.
radiograph, cephalometric
n a radiograph of the head made with precise reproducible relationships between radiograph source, subject, and film. The generally accepted distances between radiograph source and the center of the subject are 5 feet (152.4 cm) or 150 cm. The distance between subject and film is usually 12 cm but may be standardized at a different value or varied with patient size and recorded for each exposure. The two standard orientations are lateral (profile) and posteroanterior.

Cephalometric radiograph.
radiograph, composite,
n radiograph made by superimposing a radiograph of osseous tissue whose exposed border has been cut away on a radiograph of soft tissue for the purpose of detecting radiographic information concerning both the soft tissues and the osseous tissues of the head and face from a single radiographic view.
radiograph, contrast media,
n radiograph that records the shadow images of the secretory apparatus of any of the salivary glands, body cavities, or fistulous tracts after the injection of a liquid radiopaque solution.
radiograph, extraoral,
n radiograph produced on a film placed extraorally.
radiograph, follow-up,
n radiographs made during and after therapy to follow the progress or regress of a disease, determine the course of healing, or ascertain the results of treatment.
radiographs, full mouth (FMX),
n a visual image of the entire oral cavity produced by radiography. They are repeated often in order to track a patient's oral history.
radiograph, high kilovoltage,
n a radiograph taken using a higher kilovoltage than normal. This method provides a lower contrast film with more interpretive details and can be developed in a shorter time, but it subjects the surrounding areas to more radiation.
radiograph, intraoral,
n radiograph produced by placing a radiographic film within the oral cavity. See also radiography, oral.
radiograph, microscopic examination,
radiograph, occlusal,
n a special type of intraoral radiograph made with the film held between the occluded teeth.
radiograph, oral,
n the radiographic representation of shadow images of all the tissues, structures, and regions of the oral cavity and its adjacent areas and associated parts.
radiograph, panoramic,
n a tomogram of the jaws, taken with a specialized machine designed to present a panoramic view of the full circumferential length of the jaws on a single film. Also known by several brand names of machines, most of which incorporate
pan into the name.
radiograph, reference,
n a training tool in which ideal dental radiographs are compared with recently taken radiographs to study, compare, and improve interpretation and investigative skills in dental office employees.
radiograph, salivary gland,
radiograph, stereoscopic
n a pair of radiographs of a structure made by shifting the position of the radiographic tube a few centimeters between each of two exposures. Such pairs provide a three-dimensional, or stereoscopic, presentation of the recorded images.
radiograph, Towne's projection,
n.pr the radiographic view of the mandibular condyles and the midfacial skeleton.
