abstract

introdouction: the mapping of ghost images of the maxilla and the nasal cavity, which are complex structures, is very important. the position of objects that create a ghost image can differ when using various devices. the purpose of this investigation was to study the mapping of ghost images of the maxilla and the nasal cavity using a cranex d digital panoramic machine. materials and methods: the mapping of ghost images of the maxilla and the nasal cavity, which are complex structures, is very important. the position of objects that create a ghost image can differ when using various devices. the purpose of this investigation was to study the mapping of ghost images of the maxilla and the nasal cavity using a cranex d digital panoramic machine. results: when the lead ball was located in the posterior third of the septum in the anterior-posterior direction and in the middle third above the base of the septum, a ghost image was detected in panoramic view. if the ball was placed in the posterior nasal spine, the image of the object appeared extremely elongated in a horizontal direction. the same was seen when the ball was located in the posterior third of the septum in the anterior- posterior direction and near the base of the septum. conclusion: this in vitro study examining ghost image mapping of the maxilla and the nasal cavity, using a cranex d machine, revealed that the ghost envelope was limited. digital panoramic device manufacturers have attempted to reduce ghost images, and this has now been achieved with this particular digital machine.

Image quality enhancement in digital panoramic radiograph

One of the most common positioning errors in panoramic radiography is palatoglossal air space above the apices of the root of maxillary teeth. It causes a radiolucency obscuring the apices of maxillary teeth. In the case of this positioning error, the imaging should be repeated. This causes the patient be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to the pati...
