Authors introduce polarization field displays as an optically-efficient design for dynamic light field display using multi-layered LCDs. Such displays consist of a stacked set of liquid crystal panels with a single pair of crossed linear polarizers.
Computer tomography (CT) has wide application in medical imaging and reverse engineering. Due to the limited number of projections used in reconstructing the volume, the resulting 3D data is typically noisy. Contouring such data, for surface extraction, yields surfaces with localised artifacts of complex topology.
Fast and efficient statistically based image reconstruction is highly demanded for state-of-art high-resolution PET scanners. The system matrix that defines the mapping from the image space to the data space is the key to high-resolution image reconstruction.
Performance improvements for iterative electron tomography reconstruction using graphics processing units
Iterative reconstruction algorithms are becoming increasingly important in electron tomography of biological samples. In this technical note, we demonstrate that by making alternative design decisions in the GPU implementation, an additional speedup can be obtained, again of an order of magnitude.
The x-ray imaging dose from serial cone-beam computed tomography (CBCT) scans raises a clinical concern in most image-guided radiation therapy procedures. It is the goal of this paper to develop a fast graphic processing unit (GPU)-based algorithm to reconstruct high-quality CBCT images from undersampled and noisy projection data so as to lower the imaging dose.
The CUBLAS and CULA acceleration of adaptive finite element framework for bioluminescence tomography
In this paper, we for the first time introduce a new kind of acceleration technology to accelerate the AFE framework for BLT, using the graphics processing unit (GPU). Besides the processing speed, the GPU technology can get a balance between the cost and performance.
Shortly after its commercial release in May 2010, Digisens is pleased to announce the growing success of its novel electron tomography software DigiECT, which is the result of a two-year fruitful collaboration with Dr. Sergio Marco, Research Director Inserm U759, Institut Curie, Orsay, France. Moreover, DigiECT has been recently adopted by IPCMS-CNRS, a french nanotechnology institute based in Strasbourg, along with two other well-renowned research centers.
