Abstract:
A method for realizing a transmit focusing with respect to all imaging points by using plane waves of each pulse pattern having a different traveling direction which is transmitted from a transducer, the transmit focusing realization method comprising the steps of:(a) transmitting each of the pulse patterned plane wave having a linear time delay from a number of elements of the transducer;(b) storing transmit data and receive data with respect to each of the pulse patterned plane waves transmitted in step (a);(c) calculating the imaging points where each of the transmitted pulse patterned plane waves has reached, using the transmit data and the receive data stored in step (b); and(d) finding and linearly overlapping the transmitted pulse patterned plane waves having the same imaging point from the imaging points calculated in step (c).
