To date research has focused on investigating the use of ultrasonic speckle to estimate tissue motion. At adequate imaging rates, the characteristics of speckle mean that tissue can be tracked even in ...

It takes a cyclist approximately 12 s to reach a top velocity of 7.5 m/s. To estimate the cyclist's acceleration, use the formula: \(acceleration~(m/s^2) = \frac{change~in~velocity~(m/s)}{ ...
