* Instruction: Measurement of brachial artery diameter variation by ultrasound methods has commonly been used to test the endothelial function. It is known that the artery diameter is increased by flow stimulation. Therefore in the present study, the effect of external obstruction, as flow stimulation, on the radial strain of the brachial artery was(More)
OBJECTIVE The purpose of this study is to estimate a patient's organ dose (effective dose) during performance of dual X-ray absorptiometry by using the correlations derived from the surface dose and the depth doses in an anthropomorphic phantom. MATERIALS AND METHODS An anthropomorphic phantom was designed and TLDs (Thermoluminescent Dosimeters) were(More)
Tissue Doppler Echocardiography (TDE) method has been developed which permits quantification of the myocardial. In the clinic conventionally displacement is measured by use of color tissue Doppler imaging and there is no report of myocardial displacement based on integration of maximum myocardial velocity. The purpose of this study was a time integral(More)
The aim of this study was to design a new approach for the acquisition of regional radial strain from the middle portion of the interventricular septum. We designed and wrote a program in Matlab (computer-assisted method) for use on a personal computer so that the septum thickness throughout the cardiac cycle could be measured instantaneously.(More)
