A stereotaxic mechanical arm device is proposed to improve the power resolution and spatial localization of ultrasound probes for measuring arterial velocity profiles.
Ultrasonic velocimetric methods used to measure the velocity profiles in the human cardiovascular system encounter technological limitations that can be grouped into two categories: power resolution and spatial localization. The authors propose a rational procedure for obtaining arterial velocity profiles which should permit at the same time an increase of the power resolution and a reliable spatial localization. A stereotaxic device (mechanical arm) permits this procedure to be used in the clinical field. Preliminary results are presented and discussed.>
