The γ value for all the subjects of this study as a function of age.
<p>Healthy volunteers, patients with brain condition of edema and of hematoma are marked with different symbols.</p
Computer tomography (CT) of the brain of the patients involved in the study, prior to the VEPS measurements.
<p>The CT’s are divide into two groups according to clinical neurology pathology valuation: <i>Edema</i> and <i>Hematoma</i>. Moderate to severe diffuse brain edema without hemorrhage or hematomas, and subdural or epidural well located haematomas regions are evident. A description of the particular pathology is given next to each CT image.</p
Table <b>2.</b> Statistical analysis with a Mann-Whitney U test of the VEPS/CP (degrees/cm) data for the experimental groups and subgroups in ranges of frequencies in which a statistically significant difference of P<0.05 between them, was found.

Schematic of the VEPS Head/coil configuration and a block diagram of the experimental prototype.
<p>The system consists of five modules: digital synthesizer, transceiver, phase detector, data acquisition and data processing.</p
