Vector blood velocity estimation in medical ultrasound
Two methods for making vector velocity estimation in medical ultrasound are presented. All of the techniques can find both the axial and transverse velocity in the image and can be used for displaying both the correct velocity magnitude and direction. The first method uses a transverse oscillation in the ultrasound field to find the transverse velocity. In-vivo examples from the carotid artery ...

15 صفحه اولEarly atherosclerotic lesions spiraling through the femoral artery.
Atherosclerosis is common in the adductor hiatus region. The aim of this study was to evaluate atherosclerosis in relation to themorphological structure of the femoropopliteal region. Two anatomic features are thought to play an important role in the origin of these lesions: (1) curvature of the vessel, which may lead to unfavorable local hemodynamic factors that change during leg flexion; and ...
متن کاملMinimum-Time Roll Around the Velocity-Vector Maneuver of Aircraft
In this paper, some results are provided for minimum time roll about velocity vector maneuvering with thrust-vectoring and aerodynamic control in effect. The mathematical model for attitude motions of the aircraft is developed. First order necessary conditions for optimality using Pontryagen principle is applied, and the existence of an extreme family of solutions for the maneuver is shown. Mul...
