Ultrasound system and method, and ultrasound probe

An ultrasound system comprising:

• a transmission circuit which transmits a first transmission signal and a second transmission signal obtained by polarity inversion of the first transmission signal;
• an ultrasound probe which transmits a first ultrasound signal to an irradiation subject based on the first transmission signal from the transmission circuit, receives a first reflection ultrasound signal from the irradiation subject, transmits a second ultrasound signal to the irradiation subject based on the second transmission signal from the transmission circuit and receives a second reflection ultrasound signal from the irradiation subject;
• a reception circuit which receives a first reception signal corresponding to the first reflection ultrasound signal received by the ultrasound probe and a second reception signal corresponding to the second reflection ultrasound signal received by the ultrasound probe;
• a memory which stores correction data for correcting a positive-negative asymmetry between the first and second transmission signals based on an addition result of adding the first reception signal and the second reception signal in a calibration mode;
• and
• a processor configured to execute a correction computation in which an addition, a subtraction, a multiplication, or a division between the addition result and the correction data stored in the memory is performed in a diagnostic mode to compensate for the positive-negative asymmetry between the first and second transmission signals, wherein the processor performs a Fourier transform on the addition result and an inverse Fourier transform on the correction data.
