An Algorithm for Microcirculatory Blood Flow Velocity Measurement Based on Trace Orientation in Spatiotemporal Image


, : An Algorithm for Microcirculatory Blood Flow Velocity Measurement Based on Trace Orientation in Spatiotemporal Image. Sheng Wu Yi Xue Gong Cheng Xue Za Zhi 32(2): 446-450

The velocity of blood in vessels is an important indicator that reflects the microcirculatory status. The core of the measurement technology, which is based on spatiotemporal (ST) image, is to map the cell motion trace to the two-dimensional ST image, and transfer the measurement of flow velocity to the detection of trace orientation in ST image. This paper proposes a trace orientation measurement algorithm is based on Randomized Hough Transformation and projection transformation, and it is able to estimate trace orientation and flow velocity in noisy ST images. Experiments showed that the agreement between the results by manual and by the proposed algorithm reached over 90%.

Background: Over the past 20 years, the parental origin of the extra chromosome in children with trisomy 21 has been investigated with cytogenic methods of identifying morphologic variations in chromosome 21. These studies have concluded that the...
