Abstract:
1. An ultrasound imaging apparatus comprising: a probe that transmits and receives ultrasound signals to and from an object to be examined; a transmission controller that controls the ultrasound signals to be transmitted from the probe; a signal processing unit that processes the ultrasound signals received by the probe, wherein the transmission controller is configured to control the probe so as to transmit a first transmission signal and a second transmission signal, the first transmission signal is a first ultrasound signal having a center frequency of nf, the second transmission signal is a second ultrasound signal having a center frequency of mf, in which n is an even natural number, m is an odd natural number, the least common multiple of n and m is nk the signal processing unit is configured to perform: a processing to obtain a first echo signal having a center frequency of nk
