Taking the guesswork out of evaluation
Using established and novel image processing techniques (Harris corner thresholding, KLT feature-tracking, pyramidal segmentation, etc.) I developed algorithms for automating inferior vena cava (IVC) measurements via subcostal ultrasound. In this way the dynamic interplay of the respiratory and cardiac cycles as a function of volume status could be studied rigorously.
Conducting this research led to the discovery of new physiological phenomenon including detecting a respiratory induced variability to the cardiac signal present in the IVCs motion.
