Claim Text:
1. An ultrasonic diagnostic apparatus comprising: an ultrasonic probe configured to transmit and receive ultrasonic waves having acoustic powers based on supplied powers, the acoustic powers corresponding to a plurality of display modes for a predetermined time width at a time; transmission circuitry configured to supply powers to the ultrasonic probe; an upper limit storage memory configured to store upper limit values of parameters for restricting the acoustic powers in the respective display modes, wherein the parameters include an index associated with an action of ultrasonic waves on a living body, the first parameter including at least one of Ispta (spatial-peak temporal average Intensity), TI (Thermal Index), and an increase in surface temperature of the ultrasonic probe, and the second parameter comprises MI (Mechanical Index); and processing circuitry configured to determine the acoustic powers in the respective display modes so as not to exceed upper limit values of the parameters stored in the upper limit storage memory; input an instruction to increase/decrease an acoustic power, of the acoustic powers determined by the processing circuitry, which is associated with a specific display mode; specify the parameter value in the specific display mode in accordance with an input from the processing circuitry; determine an upper limit value of the parameter in a display mode different from the specific display mode based on the upper limit value of the parameter in the specific display mode stored in the upper limit storage memory and the parameter value specified by the processing circuitry; and control the transmission circuitry to supply a power to the ultrasonic probe in accordance with the specified parameter value in the specific display mode, and supply a power to the ultrasonic probe in accordance with the determined upper limit in in the display mode different from the specific display mode.
