An ultrasonic medical treatment scheme for optimally controlling the irradiation energy of the intense ultrasonic waves. In this scheme, an ultrasonic energy of the ultrasonic waves irradiated at a tissue boundary surface such as a body surface is obtained, and at least one of the driving power and the irradiation time of the ultrasonic wave generation source in the applicator is controlled such that the ultrasonic energy at the tissue boundary surface becomes less than a prescribed threshold which is determined in view of an influence on the tissue boundary surface due to the ultrasonic waves. In addition, the ultrasonic energy of the ultrasonic waves irradiated at a focal point of the ultrasonic waves can also be obtained and the applicator can be controlled such that the ultrasonic energy at the focal point becomes greater than another prescribed threshold determined in view of a medical treatment effect at the focal point due to the ultrasonic waves at the same time.
