The problem of inter-slice magnetic resonance (MR) image reconstruction is encountered
often in medical imaging applications. In such scenarios, there is a need to approximate
information not captur...
Velocity Measurement of the Flow in a Dialyzer:Visualization in the Header Using Particle Imaging Velocimetry
hollow-fiber dialyzer flow visualization particle imaging velocimetry validation data bio-fluid engineering
2009/6/9
Flow visualization was conducted in a dialyzer header using particle imaging velocimetry. A full-scale model for visualization and a mixed solution mixed with glycerin and a sodium iodide solution as ...
Development of a Miniaturized Fiber-optic Laser Doppler Velocimetry Sensor for Local Blood Velocity Measurement—Measurement of Velocity Profile of Pulsatile Blood Flow in Model Vessel—
fiber-optic LDV sensor pulsatile flow opaque fluid local velocity measurement flow
2009/6/8
In order to measure local velocity in a pulsatile flow, the optical system and the curvature of the fiber sensor tip were improved. The fiber sensor was inserted at an insertion angle of 120 deg. thr...
Measurement of Postural Responses in Horizontal Perturbation Using Angular Velocity
Horizontal perturbation Fall Angular velocity Balance
2009/6/8
The decline of the balance function induces the elderly people to fall and it causes the decrease of daily activity to become bedridden or fear of falling. The fall occurs when sudden external forces ...
Complex myograph allows the examination of complex muscle contractions for the assessment of muscle force, shortening, velocity, and work in vivo
complex muscle contractions muscle force work in vivo
