Panoramic Coronary Angiography

open access: yesJournal of the American College of Cardiology, 1998
We describe a new imaging technique for coronary angiography.The conventional approach to coronary angiography exploits static perspective imaging over multiple cardiac cycles, using a limited number of empirically selected views. This approach entails both lack and redundancy of information and may result in suboptimal visualization of the individual ...

Forensic Gender Determination by Using Mandibular Morphometric Indices an Iranian Population: A Panoramic Radiographic Cross-Sectional Study

open access: yesJournal of Imaging, 2023
Gender determination is the first step in forensic identification, followed by age and height determination, which are both affected by gender. This study assessed the accuracy of gender estimation using mandibular morphometric indices on panoramic ...

Panoramic ghosts

open access: yesOral Surgery, Oral Medicine, Oral Pathology, 1987
The panoramic artifact of ghost images is discussed and explained. The three-dimensional area within which an object must be to produce a ghost image is depicted for three panoramic machines. The radiographic features of ghosts and the objects or anatomic structures that cause them are listed.

MreNet: A Vision Transformer Network for Estimating Room Layouts from a Single RGB Panorama

open access: yesApplied Sciences, 2022
The major problem with 3D room layout reconstruction is estimating the 3D room layout from a single panoramic image. In practice, the boundaries between indoor objects are difficult to define, for example, the boundary position of a sofa and a table, and

History of Panoramic Radiography [PDF]

open access: yesActa Radiologica, 1996
The first attempts to image the whole jaw were made with intraoral radiation sources at the beginning of this century. The narrow-beam principle was described in 1922. Experimental work and development of equipment in the 1950s resulted in commercially available machines in the early 1960s. The panoramic technique originated from the need to image the
