Real–Time Imaging of Decimetre–Resolution 3D Seismic Volumes [PDF]

open access: yes, 2009
The 3D Chirp sub–bottom profiler acquires a true 3D seismic volume with decimetric horizontal and centimetric vertical resolutions, providing an ideal platform for shallow–water engineering, archaeology, military, and geological studies.

Integrated Airborne LiDAR Data and Imagery for Suburban Land Cover Classification Using Machine Learning Methods

open access: yesSensors, 2019
It is valuable to study the land use/land cover (LULC) classification for suburbs. The fusion of Light Detection and Ranging (LiDAR) data and aerial imagery is often regarded as an effective method for the LULC classification; however, more in-depth ...

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

open access: yesInternational 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 scanner

open access: yesApplied 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 of a nuclear reactor using muography measurements with Micromegas detectors [PDF]

open access: yesEPJ 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).

High-resolution 3D isotropic MR imaging of mouse flank tumours obtained in vivo with solenoid RF micro-coil [PDF]

open access: yes, 2008
The investigation of mouse flank tumours by magnetic resonance imaging (MRI) is limited by the achievable spatial resolution, which is generally limited by the critical problem of signal-to-noise ratio.
