Multi-Level Pre-Correlation RFI Flagging for Real-Time Implementation on UniBoard

Autor: Cédric, Dumez-Viou, Rodolphe, Weber, Philippe, Ravier

Because of the denser active use of the spectrum, and because of radio telescopes higher sensitivity, radio frequency interference (RFI) mitigation has become a sensitive topic for current and future radio telescope designs. Even if quite sophisticat

4D reconstruction of the left ventricle during a single heart beat from ultrasound imaging

Autor: Rodolphe Weber, Christophe Léger, Claudia Bonciu

Publikováno v: Image and Vision Computing. 19:401-412

A new acquisition system using a continuously rotating 2D ultrasound probe is proposed to reconstruct the movement and deformation of the left cardiac ventricle (LV). During only one cardiac cycle, the system acquires successive conic sections of the
