15 صفحه اولpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Phantom validation of 4D flow: independent validation of flow velocity quantification using particle imaging velocimetry
Background 4D phase contrast magnetic resonance blood flow measurements (4D PC-MR) is a promising tool for clinical assessment of cardiac function, but lack of independent validation may limit clinical adoption. Previous validation studies are limited by lack of pulsatility [1,2] or by the need of a post hoc correction factor to compensate for differences in experimental setup between 4D PC-MR ...
متن کاملFrame Rate Up-conversion Using HOE (Hierarchical Optical flow Estimation) Based Bidirectional Optical Flow Estimation
We propose a frame rate up-conversion algorithm using bidirectional optical flow estimation at each pixel based on a previously proposed Hierarchical Optical flow Estimation (HOE) algorithm. The HOE is extended from unidirectional flow estimation to bidirectional flow estimation in which a 3×3×2 multi-dimensional filter and a motion compensated image method are used for high accuracy of flow es...
متن کاملAccuracy and limitations of vector flow mapping: left ventricular phantom validation using stereo particle image velocimetory
BACKGROUND The accuracy of vector flow mapping (VFM) was investigated in comparison to stereo particle image velocimetry (stereo-PIV) measurements using a left ventricular phantom. VFM is an echocardiographic approach to visualizing two-dimensional flow dynamics by estimating the azimuthal component of flow from the mass-conservation equation. VFM provides means of visualizing cardiac flow, but...
