Ultrasonic diagnostic apparatus |
摘要 |
For the purpose of eliminating a problem that a good harmonic image cannot be obtained due to the tail of a fundamental component of previous received data intruding into a fundamental component of current received data; in the operation in a harmonic mode according to a phase inversion technique, a first ultrasonic pulse is sequentially transmitted to a plurality of foci on the same acoustic line, and a second ultrasonic pulse of a phase opposite to that of the first ultrasonic pulse is sequentially transmitted to the plurality of foci on the same acoustic line.
