Multi-frequency MRE for elasticity quantitation and optimal tissue discrimination: a two-platform liver fibrosis mimicking phantom study
Fatiha Andoh, Jin Long Yue, Felicia Julea +8
In the framework of algebraic inversion, Magnetic Resonance Elastography (MRE) repeatability, reproducibility and robustness were evaluated on extracted shear velocities (or elasti…
Partial-Field Illumination Ophthalmoscope: improving the contrast of a camera-based retinal imager
Léa Krafft, Elena Gofas-Salas, Yann Lai-Tim +5
Effective and accurate in-vivo diagnosis of retinal pathologies requires high performance imaging devices, combining a large field of view and the ability to discriminate the balli…
Waveform analysis of human retinal and choroidal blood flow with laser Doppler holography
Léo Puyo, Michel Paques, Mathias Fink +2
Laser Doppler holography was introduced as a full-field imaging technique to measure blood flow in the retina and choroid with an as yet unrivaled temporal resolution. We here inve…
Choroidal vasculature imaging with laser Doppler holography
Léo Puyo, Michel Paques, Mathias Fink +2
The choroid is a highly vascularized tissues supplying the retinal pigment epithelium and photoreceptors. Its implication in retinal diseases is gaining increasing interest. Howeve…
Development of a miniaturized motion sensor for tracking warning signs of low-back pain
Jérôme Molimard, Tristan Delettraz, Etienne Ojardias
Low-back pain (LBP) is a widespread disease which can also be highly disabling, but physicians lack of basic understanding and diagnosis tools. During this study, we have designed…
Rapidly-converging multigrid reconstruction of cone-beam tomographic data
Glenn R. Myers, Andrew M. Kingston, Shane J. Latham +5
In the context of large-angle cone-beam tomography (CBCT), we present a practical iterative reconstruction (IR) scheme designed for rapid convergence as required for large datasets…
