Abstract
An ultrasonic diagnostic imaging system is used to measure volume flow. An ultrasound probe operating in the biplane mode is used to acquire a vessel in a long axis view in a first Doppler image, and simultaneously in a transverse view in a second Doppler image. Volume flow is calculated from the transverse view of the vessel. The plane of the second image is aligned with the Doppler angle of the first image so that angle correction determined for the first image can be used for angle correction in the volume flow calculation.
Claims19
An ultrasonic diagnostic imaging system for analyzing volume flow of blood comprising:
- an ultrasound probe adapted to acquire Doppler image data from two image planes intersecting along a Doppler beam direction;
- an image data processor responsive to the acquired Doppler image data and adapted to produce two Doppler images of flow;
- a display adapted to display the two Doppler images simultaneously;
- a graphics generator, responsive to a user control, and adapted to display a Doppler line and a flow cursor over a first one of the Doppler images;
- and
- a volume flow calculator, responsive to Doppler image data of the second one of the Doppler images and a Doppler angle established by the Doppler line and the flow cursor, which is adapted to determine an angle-corrected measure of volume flow.
A method of using an ultrasonic diagnostic imaging system to conduct an ultrasound exam to measure volume flow comprising:
- scanning with an ultrasound probe adapted to operate in a biplane mode to acquire a first Doppler image of a target vessel in a long axis view;
- scanning with the ultrasound probe in the biplane mode to simultaneously acquire a second Doppler image in a transverse view of the target vessel in an image plane aligned with a Doppler angle of the first image;
- displaying the two images simultaneously;
- determining angle correction in accordance with a Doppler beam direction and a flow direction of the first Doppler image;
- and
- calculating volume flow from data of the second Doppler image using angle correction determined from the first Doppler image.
