A simple microwave technique for in vivo monitoring of human pulmonary and
cardiac activity is here presented. The technique is based on detecting the
changes in the modulation envelope of amplitude modulated waves passing through
the human body. A simplified human chest model was developed, proving an
unambiguous correlation between heart blood filling and microwave transmission
through the chest... hiện toàn bộ

Glaucoma is a progressive optic neuropathy with characteristic structural
changes in the optic nerve head reflected in the visual field. The visual-field
sensitivity test is commonly used in a clinical setting to evaluate glaucoma.
Standard automated perimetry (SAP) is a common computerized visual-field test
whose output is amenable to machine learning. We compared the performance of a
number of m... hiện toàn bộ
