3-D Tomographic Reconstruction of Rain Field Using Microwave Signals From LEO Satellites: Principle and Simulation Results

Abstract: In this paper, we propose a novel approach for 3-D rain field reconstruction using satellite signals. It uses the estimated signal-to-noise ratio (SNR) at the ground receivers for low-earth ...

Critical basilar expansion of the sphenoidal sinus associated with a spontaneous cerebrospinal fluid fistula: the relevance of multidetector computed tomographic cisternography

A 46-year-old woman presented with an intermittent nontraumatic cerebrospinal fluid (CSF) left rhinorrhea. A multidetector computed tomographic (MDCT) study was performed to investigate a CSF fistula ...
