Fiber-optic realshape sensor for enhanced doppler measurement display

A Doppler ultrasound system, comprising:

• an ultrasound probe configured to transmit an ultrasound beam through a bodily vessel from outside the bodily vessel for generating imaging data illustrative of an ultrasound image of a fluid flow through the bodily vessel;
• a vessel optical shape sensing (OSS) sensor configured to be introduced into the bodily vessel for generating vessel sensing data;
• an OSS controller configured to generate a reconstructed shape of the vessel OSS sensor within the bodily vessel relative to the ultrasound probe from the vessel sensing data;
• and
• a Doppler ultrasound controller for controlling a Doppler measurement of the fluid flow through the bodily vessel in response to the imaging data generated by the ultrasound probe and the reconstructed shape of the vessel OSS sensor,
• wherein the Doppler ultrasound controller is configured to estimate a parametric relationship between the fluid flow through the bodily vessel and a transmission by the ultrasound probe of the ultrasound beam through the bodily vessel based on a registration between the ultrasound probe and the vessel OSS sensor,
• wherein the Doppler ultrasound controller is further configured to derive the Doppler measurement of the fluid flow through the bodily vessel from the estimated parametric relationship between the fluid flow through the bodily vessel and the transmission by the ultrasound probe of the ultrasound beam through the bodily vessel, and
• wherein the parametric relationship between the fluid flow through the bodily vessel and the transmission by the ultrasound probe of the ultrasound beam through the bodily vessel includes at least an angle parameter indicative of an angle between a direction of the fluid flow through the bodily vessel within the ultrasound image relative to a direction of the ultrasound beam transmitted by the ultrasound probe.
