abstract

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 patient, it is necessary to improve the panoramic images. this paper presents a new automatic panoramic image enhancement method to reduce the effect of this positioning error. experimental results indicate that the enhanced panoramic images provide with adequate diagnostic information specially in maxilla sinusoid region. hence, this technique dispenses the need for repetition of x-ray imaging.

Evaluation of Image Magnification in Digital Panoramic Radiography

Introdouction: The aim of the present study was to investigate image magnification in digital panoramic radiography and assess the effect of anatomical sites on the magnification in both males and females. Materials and methods: In this retrospective study, digital panoramic radiographs of 48 patients with 202 implants were investigated. Implant diameter and length were measured on pan...

Panoramic radiograph in pathology.

The panoramic radiograph is an excellent extraoral radiograph to reveal abnormalities and pathologic conditions of the jaws and to show calcification of adjacent soft tissue. A single panoramic radiograph provides a significant image of the maxillofacial skeleton and dentition and often is used as a survey or screening film because of the area it covers. The panoramic radiograph does not provid...

Impact of Digital Panoramic Radiograph Magnification on Vertical Measurement Accuracy

Objectives. The purpose of this panoramic radiography study was to assess the impact of image magnification on the accuracy of vertical measurements in the posterior mandible. Methods. Six dental implants, inserted in the posterior segments of a resin model, were used as reference objects. Two observers performed implant length measurements using a proprietary viewer with two preset image magni...
