Recent advances in opg is a compilation of the latest trends in the field of orthopantogram .it gives an insight of panorama "an unobstructed view of a region in every direction "at present scar. A technology (selectively compliant articulated robor arm) in panoramic radiography where no mechanical constraints for the imaging geometry is required and image layer is fully formed by software. Promax x- ray's unique software-driven robotic arm creates more imaging program possibilities than other panoramic x-rays. In fact, the promax digital panoramic offers more than 30 different imaging programs. It provides a view of built-in specialized software automatically moves the robotic arm to the exact position necessary for your image of choice, resulting in excellent image quality time after time. Promax is also the first panoramic x-ray to offer future upgradeability to cone beam volumetric tomography (cbvt). As panoramic radiography is an essential element in present day, knowledge about panoramic radiography is must for an oral radiologist to deliver the best in the field of radiology.
