Ghost images opg
WebDimensions and, consequently, intensities of ghost images formed in an optical system can be estimated using an analytical algorithm. This algorithm enables construction of a merit function in optical design software, which returns a number proportional to the total intensity of ghost stray light. WebThe tooth appearance on the OPG was determined as a ghost image of the impacted distomolar at the contralateral side. Following the extraction of the distomolar, another OPG was performed and the ...

WebGhost artifacts are commonly seen in transverse echograms of pelvic organs because the re … A ghost artifact is produced when refraction of an ultrasound beam occurs in one part of a scanning plane. WebConversely, when the structure is located between the tube head and rotation centre, there can be formation of a secondary or ghost image. This secondary image appears on the opposite side of the film in a slightly superior position, and is magnified and distorted.
WebThis is a simplified diagram replicating a common artefact seen on OPG. As the x-ray source and detector rotate around the patient dense objects (such as an earring) at the edge of the case, outside the focal trough - can cause 'ghost images'. These are seen at the contralateral aspect of the image and are distorted.
