Quantitative evaluation of treadmill test induced ST-T changes using body surface mapping.

Treadmill exercise test using body surface mapping. A quantitative diagnostic method for coronary artery disease.

In order to evaluate coronary artery disease quantitatively we recorded body surface maps before and after treadmill exercise in 27 patients suspected of having coronary artery disease. Electrocardiograms were recorded from 87 points on the anterior and posterior chest wall. The pre-exercise ST level was subtracted from post-exercise ST level at each lead point and an ST difference MAP was cons...

Total body surface potential mapping during exercise: QRS-T-wave changes in normal young adults.

Total body surface potential distributions were recorded from 20 normal young adults, 20-35 years old, during multistage maximal exercise testing on a bicycle ergometer. Using a system for measuring total body surface potential distributions from measurements at 24 locations, high-quality potential maps were obtained during exercise without requiring wave form averaging or special modes of exer...

Diagnosis of patients with Parkinson's disease using quantitative susceptibility mapping

Introduction: Parkinson'sdisease isassociated withirondeposition in the brain. The T2-weighted imaging, T2* mapping, R2 mapping and Quantitative Susceptibility Mapping (QSM) are three common methods to evaluating the iron deposition in brain. Among three methods the QSM is more sensitive than others. Few studies have been used QSM for evaluating the iron deposition in the basa...

Quantitative Evaluation of Human Body Surface Modeling Methodology

Evaluation of a Virucidal Quantitative Carrier Test for Surface Disinfectants

Surface disinfectants are part of broader preventive strategies preventing the transmission of bacteria, fungi and viruses in medical institutions. To evaluate their virucidal efficacy, these products must be tested with appropriate model viruses with different physico-chemical properties under conditions representing practical application in hospitals. The aim of this study was to evaluate a q...
