Method to Measure Wall Motion and Wall Thickness Using Contrast Enhanced Fluoroscopy

C11284 Method to Measure Wall Motion and Wall Thickness Using Contrast Enhanced Fluoroscopy BackgroundMost invasive angiograms end in the measurement of heart function by performing a ventriculogram. Performance of left ventriculography (LVG) requires additional contrast agent (about 30 – 40ml), catheter and time. Scientists at Johns Hopkins...
