A Feasibility Study on Microwave Imaging for Brain Stroke Monitoring
The adoption of microwave imaging as a tool for noninvasive monitoring of brain stroke has recently gained increasing attention. In this respect, the paper aims at providing a twofold contribution. First, we introduce a simple design tool to devise guidelines to properly set the working frequency as well as to choose the optimum matching medium needed to facilitate the penetration of the probin...
متن کاملMicrowave Head Imaging for Stroke Detection
This paper proposes an algorithm for wide-band microwave imaging for the detection of a hemorrhagic stroke. A realistic head phantom and finite-difference time-domain program are used to estimate back-scattered signals which are subsequently used in the image reconstruction process. The proposed imaging approach can lead to a portable and cost effective system; particularly suitable for rural m...
متن کاملMicrowave Imaging Using SAR
Polarimetric Synthetic Aperture Radar (Pol.-SAR) allows us to implement the recognition and classification of radar targets. This article investigates the arrangement of scatterers by SAR data and proposes a new Look-up Table of Region (LTR). This look-up table is based on the combination of (entropy H/Anisotropy A) and (Anisotropy A/scattering mechanism α), which has not been reported up now. ...
متن کاملA Data Focusing method for Microwave Imaging of Extended Targets
This paper presents a data focusing method (DFM) to image extended targets using the multiple signal classification (MUSIC) algorithm. The restriction on the number of transmitter-receiver antennas in a microwave imaging system deteriorates profiling an extended target that comprises many point scatterers. Under such situation, the subspace-based linear inverse scattering methods, like the MUSI...
متن کاملUtility of repeat brain imaging in stroke.
PURPOSE To determine the utility of repeat brain imaging in patients with stroke. METHODS We reviewed the medical records of 98 consecutive patients in whom stroke was diagnosed between January 1 and December 31, 1991. We noted the number of brain scans performed, the indications cited, and whether repeat imaging changed the therapeutic decisions or final diagnosis. RESULTS Ninety-eight pat...
