Microwave measurements from an antenna array placed around the head can be used to detect changes in dielectric properties of the brain. In this paper an algorithm is developed to provide localization information of the site of an intra cerebral hemorrhage. The algorithm is based in the hypothesis that scattering parameters for an antenna pair close to the site of the bleeding will undergo larger changes. The change is measured using a feature derived from the scattering measurements using higher order singular value decomposition and is compared with the feature derived from measurements from a control group of healthy subjects. The proposed algorithm is evaluated on clinical data and the result is compared with computed tomography images of the patients. |
