摘要： An ultrasonic flowmeter for measuring a flow rate in a conduit. A pair of ultrasonic transducers are disposed in a conduit so as to oppose each other such that a line connecting the pair of transducers is inclined by a predetermined angle with respect to a fluid flowing direction. The ultrasonic flowmeter includes: driving means for simultaneously driving the pair of ultrasonic transducers; means for measuring the primary time difference between a time when one ultrasonic transducer receives an ultrasonic wave which is radiated from the other ultrasonic transducer and a time when the other transducer receives an ultrasonic wave which is radiated from the first ultrasonic transducer. Additionally, a time difference between the time measured when one ultrasonic transducer receives an ultrasonic wave radiated from one ultrasonic transducer and reflected by the other ultrasonic transducer and a time measured when the other ultrasonic transducer receives an ultrasonic wave radiated from the other ultrasonic transducer and reflected by one ultrasonic transducer. Primary and secondary time difference data is produced by adding signs in accordance with the arrival order of the ultrasonic waves. Time difference data is used to calculate an actual flow rate of the fluid using data of the propagation time difference data.

摘要： A plurality of impedance pneumographs for measuring impedances at the locations of a human thorax are provided together with a pneumotachograph for measuring an amount of respiration. An impedance value measured at the inhalation starting point is subtracted from an impedance value measured at other time points to obtain an impedance variation. The impedance variations corresponding to the locations of the thorax are added to obtain a sum of the impedance variations. A ratio of the impedance at each location of the thorax to the sum of the impedance variations is calculated and an amount of ventilation at each location of the thorax is found by the impedance ratio and respiration amount.

摘要： An ultrasonic lithotrity apparatus is held such that its installation position can be adjusted with respect to a stone formed in a living body, and has an ultrasonic lithotrity transducer for emitting an intense ultrasonic wave for breaking up the stone. The ultrasonic lithotrity transducer emits a weak ultrasonic wave immediately before every single or every predetermined number of intense ultrasonic waves is emitted. The position of a stone in the living body can be determined in accordance with a reflected wave of the weak ultrasonic wave. On the basis of reception of the reflected echo signal, the position of the stone is determined. In accordance with the determination result, electronic circuits determine whether the weak or intense ultrasonic wave is to be emitted from the ultrasonic lithotrity transducer.

摘要： An ultrasonic wave medical treatment in which the position of the focal point of the ultrasonic waves, the temperature in a vicinity of the object to be treated, and the effect of the treatment can be determined easily and accurately. The three-dimensional image information of the object to be treated obtained by a computed tomography device is utilized in locating the focal point. In case of using a nuclear magnetic resonance imaging device as the computed tomography device, the T2 weighted image and the chemical shift data can be used in checking the effect of the treatment and the temperature in a vicinity of the object. The endocavitary probe equipped with temperature and intensity sensors may also be used. The ultrasound tomographic images obtained by the ultrasound tomographic imaging device may also be used in conjunction with the three-dimensional image information. Sequential shifting of the focal point of the ultrasonic waves may be employed to reduce adverse influence due to the cavitation.

摘要： An ultrasound therapy system comprises an annular array ultrasound transducer, a mechanical driver, a transmitter/receiver, and a controller. The controller includes an imaging controller, a heating controller, and a select controller. The mechanical driver mechanically drives the transducer to change at least one of the position and direction of ultrasound beams transmitted and received by the transducer. The transmitter/receiver may supply drive signals to the respective elements of the transducer, and receive the ultrasound echo signals from the elements. The imaging controller gives a first drive command to the transmitter/receiver, and at the same time drives the mechanical driver, radiates scanning ultrasound beams for tomographing through the transducer, and obtains a tomogram of a target portion in a patient from the echo signal derived from the transmitter/receiver. The heating controller drives the transmitter/receiver by a second drive signal to cause the transducer to radiate heating ultrasound beams. The heating ultrasound beams heat the target. These imaging and heating controllers are selectively activated by the select controller.
