Ultrasonic diagnostic apparatus and ultrasonic wave transmission/reception control method

An ultrasonic diagnostic apparatus includes an memory, an determination unit, an instruction unit, a specifying unit, and an redetermination unit. The memory stores upper limit values of parameters for restricting the powers in display modes. The determination unit determines the powers in the modes so as not to exceed upper limit values of the parameters. The instruction unit inputs an instruction to increase/decrease the power of a specific mode. The specifying unit specifies the parameter value in the specific mode. The redetermination unit determines an upper limit value of the parameter in a mode different from the specific mode based on the upper limit value of the parameter in the specific mode and the parameter value specified by the specifying unit.
