Calculation of volume flow rate by the proximal isovelocity surface area method: Simplified approach using color Doppler zero baseline shift

Objectives. The goal of this study was to develop an accurate, simplified proximal isovelocity surface area (PISA) method for calculating volume flow rate using lower blue-red interface velocity produced by a color Doppler zero baseline shift technique. Background. The Doppler color proximal isovelo...
