Abstract: A probe (10) transmits and receives diagnostic ultrasound and therapeutic ultrasound. A transmission unit (12) forms a transmission beam of the therapeutic ultrasound having a higher wave number than the diagnostic ultrasound and scans the transmission beam of the therapeutic ultrasound in a therapeutic region set inside a diagnostic region by controlling the probe (10). Since the therapeutic ultrasound having a higher wave number than the diagnostic ultrasound is used, the therapeutic effect is higher than when using a therapeutic ultrasound having a similar wave number to the diagnostic ultrasound, and since the transmission beam of the therapeutic ultrasound is scanned in the therapeutic region, the therapeutic effect is higher than when the transmission beam of the therapeutic ultrasound is not scanned.

Abstract: A modulation frequency control unit (36) controls a displacement-use transmission unit (34) such that displacement-use ultrasonic beam (EB) is subjected to modulation processing using a relatively high modulation frequency and a relatively low modulation frequency. A displacement measurement unit (24) measures the displacement of a tissue in a treatment area (P) at each of the modulation frequencies, and a coagulation measurement unit (25) measures local coagulation in the treatment area (P) on the basis of the measurement result of the displacement at the relatively high modulation frequency, and measures wide-area coagulation in the treatment area (P) on the basis of the measurement result of the displacement at the relatively low modulation frequency.

Abstract: A signal generation unit 10 generates, and sends to a transmission circuit 12, a driving signal for forming a transmission pulse. A probe 14 is transmission controlled to transmit ultrasound at a transmission frequency which is set using, as a reference, a resonance frequency of a bubble administered into a living organism, and also at a transmission sound pressure which is set using an expansion ratio of the bubble as a reference. The signal generation unit 10 outputs a transmission pulse having a waveform corresponding to a center frequency of about 1.5 MHz and a transmission sound pressure of about 200 to 300 kPa. With this structure, it is possible to increase a harmonic component obtained from the bubble while suppressing a harmonic component obtained from real tissue, so that extremely high CTR can be obtained.

Abstract: When reagent was discharged in a physiological tissue reagent treatment apparatus, it was troublesome to retain the sample so that it was not discharged together with the reagent. This apparatus offers an improvement on this point, saves work involved in reagent treatment and enables lower costs to be attained. Samples 70 are held in separate sample containers 8. The base of this sample container 8 comprises a mesh 64. Consequently, when the sample container 8 is inserted in a reagent bath 6 in which reagent has collected, reagent flows from this mesh 64 into the container 8. Reagent may flow also from a flow hole 66. The reagent which has flowed into the container 8 acts on the sample 70, and reagent treatment takes place. The reagent in a plurality of the sample containers 8 set in a container holder 10, is then aspirated by a pump 30, or by a nozzle inserted together with the container 8 in the reagent bath, via the mesh 64 of the container.

Abstract: A physiological tissue sample on a glass slide is treated by a reagent. A reagent bath is formed so that its horizontal depth becomes progressively larger from the lower part to the upper part. In a first treatment mode, a small amount of reagent is introduced in the reagent bath, and a sample plate is introduced into the bath up to a first treatment position. In a second treatment mode, a large amount of reagent is introduced in the reagent bath, and a sample plate is introduced into the bath up to a second treatment position.
