Claims
- 1. An ultrasonic therapeutic apparatus comprising:a source of therapeutic ultrasonic waves; driving means for driving said source to generate therapeutic ultrasonic waves; a magnetic resonance diagnostic apparatus or measuring the temperature distribution in the vicinity of the focus onto which said therapeutic ultrasonic waves converge; and means for adjusting drive conditions of said drive means according to said temperature distribution.
- 2. An ultrasonic therapeutic apparatus comprising:a source of therapeutic ultrasonic waves; an ultrasonic probe; driving means for driving said source to generate first ultrasonic waves; forming means for forming intensity distribution of the first ultrasonic waves on the basis of echoes of said first ultrasonic waves received through said ultrasonic probe; magnetic resonance diagnostic means for measuring one-dimensional temperature distribution; and estimation means for estimating two-dimensional temperature distribution on the basis of said intensity distribution and said one-dimensional temperature distribution.
- 3. The apparatus according to claim 2, wherein said estimation means estimates said two-dimensional temperature distribution on the basis of a total energy of said first ultrasonic waves and said one-dimensional temperature distribution.
