摘要： A schlieren imaging system provides quantitative images suitable for testing medical equipment. One embodiment includes precision optics which form an image of a volume of a medium through which an ultrasonic acoustic wave propagates. A spatial filter passes diffracted light but blocks other light. A camera forms an image of the medium from the diffracted light so that regions of the medium which diffract light have higher light intensity in the image. From image intensities, a processor determines acoustic pressures or intensities, typically as a value indicating an integral of the acoustic pressure or intensity along an optical path through the volume. Integrated pressure is determined from a look-up table which relates predicted light intensity to pressure values which cause the predicted light intensity. The system is calibrated by forming an image of a reference ultrasonic acoustic wave and determining a relation between the image intensities and predicted intensities. The system may include a timing circuit which periodically activates and deactivates a transducer and causes emission of synchronized pulses of light. The pulses of light are synchronized with a selected delay after activations of the transducer, so that an image is formed which shows an ultrasonic acoustic wave that has evolved during the delay.

摘要： Hair is permanently removed from a patient's skin by transcutaneously focusing high intensity acoustic energy at a hair follicle and applying sufficient energy to destroy the follicle, whereby hair is removed and regrowth is prevented. Typically, a region of a patient's skin would be ultrasonically imaged to show the location of a plurality of individual hair follicles. The individual imaged hair follicles are then treated using a system which automatically directs the high intensity acoustic energy at each follicle.

摘要： A treatment tool such as a catheter, MIS or other surgical tool apparatus for placement within a heart chamber, organ aperture or other body opening and axial ranging therein, the apparatus particularly adapted for laser-assisted percutaneous transmyocardial revascularization (MTR). At the distal end of the tool is an annular ultrasound transducer with associated structure, positioned to transmit ultrasound signals substantially axially aligned with the axis of the treatment tool to the cardiovascular tissue, the transducer further receiving returning signals from the cardiovascular tissue to be treated. In a preferred embodiment, the transducer comprises a piezoelectric crystal material. The transducer assembly is attached to the distal tip of the tool such that a laser delivery means or other functional device can be extended through the lumen of the tool and the annular ultrasound transducer. In a preferred embodiment, the invention is a modular ultrasound device capable of being detachably attached to a steerable catheter, MIS or other surgical tool apparatus. The system also comprises a signal interface extending from the ultrasound transducer and signal processing component operatively connected to the signal interface for real time determination of at least one boundary surface of cardiovascular tissue relative to one or more positions of the distal tip of the treatment tool. A method of delivering laser energy to tissue is disclosed, the method including the steps of positioning the firing tip of a laser delivery means adjacent the front surface of the tissue, delivering laser energy to the tissue, transmitting ultrasound energy to the tissue, receiving ultrasound signals reflected from at least the rear surface of the tissue, and determining the distance betwveen the firing tip of the laser delivery means and the rear surface of the tissue. In a preferred embodiment, the method includes quantitative determination of the contractility or motion of the beating heart, such that changes in the depth of tissue can be used to control the channel depth or other treatment parameters. Retrolasing can also be achieved by mechanically piercing the tissue to a determined depth based on axial ranging measurements, and retracting the treatment tool while simultaneously delivering laser energy therefrom.

摘要： Hair is permanently removed from a patient's skin by transcutaneously focusing high intensity acoustic energy at hair follicles and at dermal papilla regions during a telogen phase of hair growth and applying sufficient energy to destroy said follicles and said dermal papilla regions, so that hair is removed and regrowth is prevented. Typically, a region of a patient's skin is first ultrasonically imaged to show the location of a plurality of individual hair follicles and dermal papilla regions. The imaged hair follicles and dermal papilla regions are then treated using a system which automatically directs high intensity acoustic energy at each follicle and dermal papilla region.

摘要： The effect of ultrasound irradiation of a human or other animal body portion is enhanced by operating the body portion as a trapped mode resonator. The intensity and location of resonances within the body portion is controlled by controlling such variables as the amplitude, frequency and/or phase of the ultrasound irradiation. This minimizes the overall energy required to be applied to the body portion in order to achieve a desired localized intensity level.

摘要： A method of treatment by ultrasound comprises providing a first, ultrasound field intensity-to-voltage transducer sized for insertion into the vicinity of a treatment site and a second ultrasound treatment transducer. The free field intensities created by the second transducer in response to various second transducer exciting signal levels are determined. The first transducer outputs in the free field in response to various second transducer exciting signal levels are also determined. The first transducer is inserted into the vicinity of the treatment site, and the second transducer is positioned to create an ultrasound field at the treatment site. The distance from the second transducer to the first transducer is determined. An exciting signal is applied to the second transducer. The output of the first transducer is determined. The level of the exciting signal applied to the second transducer, the determined distance and the first transducer output are employed to determine the attenuation coefficient of the tissues between the second transducer and the first transducer.
