| 1. A method for determining a position of a mechanically rocked scan within a volume, the method comprising:
(a) determining first and second velocity parameters of a mechanically rocked array at first and second different positions,
respectively, the velocity parameter being different at each of the first and second positions; and
(b) setting first and second scan positions as a function of the first and second velocity parameters, respectively;
wherein (a) comprises storing an array velocity parameter profile having the velocity parameters for various scan plane positions
throughout the volume scan, the various scan plane positions including the first and second positions.
