Imaging the dynamics of cardiac fiber orientation in vivo using 3D Ultrasound Backscatter Tensor Imaging
Clement Papadacci, Victor Finel, Jean Provost +6
The assessment of myocardial fiber disarray is of major interest for the study of the progression of myocardial disease. However, time-resolved imaging of the myocardial structure…
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…
Non-invasive Evaluation of Aortic Stiffness Dependence with Aortic Blood Pressure and Internal Radius by Shear Wave Elastography and Ultrafast Imaging
Clement Papadacci, T. Mirault, B. Dizier +3
Elastic properties of arteries have long been recognized as playing a major role in the cardiovascular system. However, non-invasive in vivo assessment of local arterial stiffness…
Imaging of non tumorous and tumorous human brain tissue with full-field optical coherence tomography
Osnath Assayag, Kate Grieve, Bertrand Devaux +5
A prospective study was performed on neurosurgical samples from 18 patients to evaluate the use of Full-Field Optical Coherence Tomography (FF-OCT) in brain tumor diagnosis. FF-OCT…
