Resorption of retromolar bone grafts after alveolar ridge augmentation—volumetric changes after 12 months assessed by CBCT analysis

International Journal of Implant Dentistry, 2021
In this pilot study, a volumetric analysis of retromolar onlay bone grafts over a period of 12 months was conducted, using repeated CBCT imaging combined with automated image registration.

3D imaging of a nuclear reactor using muography measurements with Micromegas detectors [PDF]

EPJ Web of Conferences, 2023
Transmission muography is a non-invasive and non-destructive imaging method which allows to estimate the integrated density of a volume in a given direction (also referred as opacity).

3D imaging scanner

Applied Optics, 2018
This paper proposes a multi-view three-dimensional display method based on a scanning imaging system with the light-intensity characteristic recorded by an improved flatbed scanner. Within the effective scanning depth of the imaging sensor, two transmission images are each simultaneously acquired by two linear CCD modules with different focal planes ...

3D-Imaging Endoscopy Through Electronic Focusing

IEEE Photonics Journal
Conventional endoscopic systems provide two-dimensional images of three-dimensional structures. Real depth information is lost in these systems. Therefore, depth perception relies uniquely on monocular cues, such as occlusions, shadows or motion parallax.

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.
