Parallelization of iterative reconstruction algorithms in multiple modalities [PDF]

2014 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC), 2014
In this work we have parallelized the Maximum Likelihood Expectation-Maximization (MLEM) and Ordered Subset Expectation Maximization (OSEM) algorithms for improving efficiency of reconstructions of multiple pinholes SPECT, and cone-bean CT data. We implemented the parallelized versions of the algorithms on a General Purpose Graphic Processing Unit ...

Semantics-Reconstructing Hashing for Cross-Modal Retrieval [PDF]

, 2020
Retrieval on Cross-modal data has attracted extensive attention as it enables fast searching across various data sources, such as texts, images and videos. As one of the typical techniques for cross-model searching, hashing methods project features with high dimension into short-length hash codes, thus effectively improving storage and retrieval ...

Wavefront reconstruction by modal decomposition

Optics Express, 2012
We propose a new method to determine the wavefront of a laser beam based on modal decomposition by computer-generated holograms. The hologram is encoded with a transmission function suitable for measuring the amplitudes and phases of the modes in real-time. This yields the complete information about the optical field, from which the Poynting vector and

Building a Modal-balanced BlockChain with Semantic Reconstruction

CoRR, 2023
The current large blockchain systems (BTC Lightning network, Ethereum, etc.) are generally facing the problems of low persistence rates and high storage costs. Therefore, users tend to store single modal (textual) information on the existing blockchain systems.

DIFFERENT MODALITIES OF RECONSTRUCTION IN FOURNIER GANGRENE [PDF]

Zagazig University Medical Journal, 2013
Background: Fournier gangrene is an acute and potentially lethal necrotising fasciitis that involves the scrotum and perineum. This disease can result in the loss of skin and soft tissue. Multiple options for reconstruction of the scrotum are available. To repair the scrotal and perineal defects remains a surgical challenge.

Modal Shapes Selection Criterion for Modal Reconstruction Aimed at Structural Health Monitoring

Engineering Proceedings
This paper aims to demonstrate the applicability of a modal selection criterion based on strain energy potential for describing static deformations in a commonly used engineering geometry, specifically a circular plate. The analytical model relies on the

Surface Measurement Using Compressed Wavefront Sensing

Photonic Sensors, 2018
Compressed sensing leverages the sparsity of signals to reduce the amount of measurements required for its reconstruction. The Shack-Hartmann wavefront sensor meanwhile is a flexible sensor where its sensitivity and dynamic range can be adjusted based on
