    摘要: Apparatus and methods for measuring and analyzing blood flow in vessels in the bodies of living subjects are provided. The true velocity vector, or a projection thereof onto a scan plane, for blood flowing at a location in a vessel is determined from multiple Doppler velocity components. The true velocity vector is displayed as a directional marker on an image comprising the vessel. The true velocity magnitude and angle, and scalar blood flow characteristics derived therefrom, are plotted as a functions of time and/or position across the depiction of the blood vessel in the image. Time intervals for which blood flow characteristic data is displayed and/or determined may be user configurable.

    摘要: An ultrasound probe is equipped with a transducer element array and an internally located position marker trackable by a position sensing system or the like. The position marker is supported by a movement and rotation constraining fixture. The fixture is rigidly connected to the transducer element array of the probe. The fixture constrains the position and orientation of the position marker to match a spatial reference relationship with the transducer element array in the position marker's constrained degrees of freedom. The position marker may moved along and rotated in its unconstrained degrees of freedom to match the spatial reference relationship with the transducer element array.
