Rotational panoramic radiographs-unusual triple images
Currently clinicians advice rotational panoramic radiography (RPR) for preliminary investigation. Despite few inherent limitations, rotational panoramic radiography still remains the diagnostic tool of choice. Abnormal structures such as a supernumerary tooth or a device falling within the certain central regions in conventional RPR images may mislead the clinicians towards an inaccurate diagno...
متن کاملRotational panoramic versus intraoral rectangular radiographs for evaluation of peri-implant bone loss in the anterior atrophic mandible.
PURPOSE In patients with atrophic mandibles, elevation of the floor of the mouth often prevents intraoral rectangular radiography for longitudinal follow-up studies, while extraoral techniques such as panoramic radiographs tend to produce distorted views of the interforaminal region. In this study, intraoral rectangular radiographs and panoramic radiographs were compared for their accuracy in e...
متن کاملThe information content of panoramic images I: The rotational errors and the similarity of views in rectangular experimental arenas.
Animals relocating a target corner in a rectangular space often make rotational errors searching not only at the target corner but also at the diagonally opposite corner. The authors tested whether view-based navigation can explain rotational errors by recording panoramic snapshots at regularly spaced locations in a rectangular box. The authors calculated the global image difference between the...
متن کاملPersonal Panoramic Perception
For a myriad of military and educational situations, video imagery provides an important view into a remote location. These situations range from remote vehicle operation, to mission rehearsal, to troop training, to route planning, to perimeter security. These situations require a large field of view and most would benefit from the ability to view in different directions. Recent research has le...
متن کاملMultiperspective panoramic depth imaging
In this chapter we present a stereo panoramic depth imaging system, which builds depth panoramas from multiperspective panoramas while using only one standard camera. The basic system is mosaic-based, which means that we use a single standard rotating camera and assemble the captured images in a multiperspective panoramic image. Due to a setoff of the camera’s optical center from the rotational...
