Abstract
A system and methods for measuring the volume flow of fluid in an enclosed structure with an ultrasound system is provided. Manual designation of flow angles and areas may not be necessary. Velocities along two or more different scan lines in a first scan plane are obtained to determine an angle of flow within the enclosed structure. A Doppler spectrum parameter is measured from a transmission in a second scan plane substantially perpendicular to the first scan plane. Volume flow is calculated from the flow angle and the parameter. The scan planes are associated with rotating a linear array transducer or holding a multi-dimensional transducer in place. A C-scan method with a linear transducer may also be used.
