Patient-specific reconstruction of volumetric computed tomography images from a single projection view via deep learning [PDF]

Nature Biomedical Engineering, 2019
Tomographic imaging using penetrating waves generates cross-sectional views of the internal anatomy of a living subject. For artefact-free volumetric imaging, projection views from a large number of angular positions are required. Here we show that a deep-learning model trained to map projection radiographs of a patient to the corresponding 3D anatomy ...

Three-Dimensional Photon Counting Optical Encryption With Enhanced Visual Quality and Security Level

IEEE Access, 2021
In this paper, we propose three-dimensional (3D) photon counting double random phase encryption (DRPE) with enhanced visual quality and security level. Conventional 3D photon counting DRPE can quickly encrypt the data by using the 4f optical system and ...

Three-Dimensional (3D) Visualization under Extremely Low Light Conditions Using Kalman Filter

Sensors, 2023
In recent years, research on three-dimensional (3D) reconstruction under low illumination environment has been reported. Photon-counting integral imaging is one of the techniques for visualizing 3D images under low light conditions. However, conventional

Intervertebral Disc Segmentation and Volumetric Reconstruction From Peripheral Quantitative Computed Tomography Imaging [PDF]

IEEE Transactions on Biomedical Engineering, 2009
An automatic system for segmenting and constructing volumetric representations of excised intervertebral discs from peripheral quantitative computed tomography (PQCT) imagery is presented. The system is designed to allow for automatic quantitative analysis of progressive herniation damage to the intervertebral discs under flexion/extension motions ...
