Structured mesh generation from doppler ultrasound images

Non-invasive ultrasound imaging of human arteries is a widely form used for medical diagnosis of arterial diseases, like atherosclerosis. The objective of this paper is to present a methodology for patient-specific construction of a structured mesh of the carotid artery bifurcation from images obtained with Doppler ultrasound techniques.

Comparison of different methods of heart rate entropy analysis during acute anoxia superimposed on a chronic rat model of pulmonary hypertension

Acute life-threatening situations are particularly critical when superimposed on chronic diseases. The objective of this study was the assessment of heart rate (HR) dynamics during episodes of acute anoxia superimposed on a rat model of chronic pulmonary hypertension. In 10 adult Wistar rats, five weeks after pulmonary hypertension induction with Monocrotaline, we analysed eight 1-min HR segments, during episodes of baseline, mechanical ventilation and acute anoxia, using linear indices, appr...
