Dual-modal Image Reconstruction for Electrical Impedance Tomography with Overlapping Group Lasso and Laplacian Regularization [PDF]

, 2023
Objective: Electrical Impedance Tomography (EIT) is a promising biomedical imaging modality, yet EIT image reconstruction remains an open challenge due to its severe ill-posedness. High-quality EIT image reconstruction algorithms are desired.

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.

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

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.
