Choroid Plexus Cyst. The second trimester ultrasound examination (sonogram) will sometimes identify a cyst or cysts in the choroid plexus. The choroid plexus is a tissue in the brain that produces cerebrospinal fluid. Fluid-filled cysts, called choroid plexus cysts or CPCs, are identified by ultrasound in approximately 1-3% of all pregnancies scanned between 16 and 24 weeks gestation.

Interpolation is a specific case of curve fitting, in which the function must go exactly through the data points. A different problem which is closely related to interpolation is the approximation of a complicated function by a simple function.Suppose we know the function but it is too complex to evaluate efficiently.elated concepts Edit. The term extrapolation is used if we want to find the value of f at a point x which is outside of the points x k at which f is given. In curve fitting problems, the constraint that the interpolant has to go exactly through the data points is relaxed.
