DeepMB: Deep neural network for real-time optoacoustic image reconstruction with adjustable speed of sound

no code implementations29 Jun 2022 Christoph Dehner, Guillaume Zahnd, Vasilis Ntziachristos, Dominik Jüstel

Multispectral optoacoustic tomography (MSOT) is a high-resolution functional imaging modality that can non-invasively access a broad range of pathophysiological phenomena by quantifying the contrast of endogenous chromophores in tissue.

Carotid artery wall segmentation in ultrasound image sequences using a deep convolutional neural network

1 code implementation28 Jan 2022 Nolann Lainé, Guillaume Zahnd, Herv é Liebgott, Maciej Orkisz

The objective of this study is the segmentation of the intima-media complex of the common carotid artery, on longitudinal ultrasound images, to measure its thickness.

Adaptive Image-Feature Learning for Disease Classification Using Inductive Graph Networks

no code implementations8 May 2019 Hendrik Burwinkel, Anees Kazi, Gerome Vivar, Shadi Albarqouni, Guillaume Zahnd, Nassir Navab, Seyed-Ahmad Ahmadi

We propose a new network architecture that exploits an inductive end-to-end learning approach for disease classification, where filters from both the CNN and the graph are trained jointly.

Dynamic Block Matching to assess the longitudinal component of the dense motion field of the carotid artery wall in B-mode ultrasound sequences -- Association with coronary artery disease

no code implementations6 Sep 2018 Guillaume Zahnd, Kozue Saito, Kazuyuki Nagatsuka, Yoshito Otake, Yoshinobu Sato

Purpose: The motion of the common carotid artery tissue layers along the vessel axis during the cardiac cycle, observed in ultrasound imaging, is associated with the presence of established cardiovascular risk factors.
