Abstract
A system improves accuracy of blood flow peak velocity measurements as well as the speed and precision of an MR data acquisition workflow. A system for blood flow velocity determination in MR imaging comprises an MR imaging system. The MR imaging system acquires a three dimensional (3D) MR imaging dataset of a patient anatomical volume of interest and a one dimensional (1D) MR imaging dataset within the volume of interest automatically aligned in response to 3D vector directional information. An image data processor derives the 3D vector directional information by, deriving velocity magnitude data using the acquired 3D MR imaging dataset, identifying maximum velocity data using the derived velocity magnitude data and transforming the identified maximum velocity data to provide the 3D vector directional information. A calculation processor uses the acquired 1D MR imaging dataset to calculate a blood flow velocity in a direction determined by the 3D vector directional information.
