摘要： Apparatus for sensing particles in a fluid medium comprising an ultrasonic resonant cavity for containing a fluid medium. A first transducer on one side of the cavity continuously propagates thereacross ultrasonic compressional waves whose phase and amplitude are perturbed by the presence of particles in the fluid medium. A second transducer positioned on the opposite side of the cavity from the first transducer substantially parallel to and in registry therewith receives the ultrasonic waves and converts them to rf electric waves of the same frequency, the rf electric waves having their phases and amplitudes modulated in response to any perturbations in the ultrasonic waves. The rf waves are amplified and fedback to the first transducer thereby to establish an oscillatory circuit. An attenuator in the oscillatory circuit causes its operation to be marginally oscillatory whereby small changes in the amplitude of the rf waves caused by any perturbations in the ultrasonic waves produce relatively large changes in the amplitude thereof. A detector responsive to perturbations in the rf wave demodulates the amplified rf wave to produce signals indicative of the presence of particles in the fluid medium. Thus, enhanced sensitivity to small changes in the ultrasonic properties of the fluid medium caused by the presence of particles therein is achieved.

The deflectable member may be interconnected to the catheter body by a live hinge. The catheter may include a lumen extending from a proximal end of the catheter body to the distal end. The lumen may be used to deliver an interventional device to a point distal to the distal end of the catheter body.

摘要： A sheath for receiving an ultrasonic probe and for defining the relative position of the probe with respect to a biopsy gun or a rigid needle is used for precise placement of the biopsy gun or needle tip in a structure. The sheath may comprise a keyhole-shaped slot for placement of a rigid needle through a puncture separate from a surgical port through which the sheath itself and the probe are introduced. A flexible catheter can thus be placed in a structure, using the ultrasonic probe to monitor its placement, followed by removal of the probe sheath and surgical port, leaving the catheter in place.

摘要： The present invention provides an apparatus that is useful in obtaining blood flow information. The device includes a carrier that, in preferred embodiments of the invention, includes either a catheter or guide wire. The device further includes at least one transducer that is capable of generating and/or receiving an ultrasonic signal that departs or is received, respectively, by the transducer at an angle to the surface of the transducer that is exposed to the blood flow.

Another embodiment of the device employs a transducer that utilizes the grating lobe effect to transmit and/or receive ultrasonic signals at an angle to the surface of the transducer that is exposed to the blood flow.

摘要： An ultrasonic diagnostic imaging system is described in which a multi-element transducer array transmits a focused beam of energy from the transducer elements. As the depth of focus is varied between near and far field focusing under operator control, the nominal frequency of the transmitted ultrasound energy is varied correspondingly by the system, from relatively high frequency transmission in the near field to relatively low frequency transmission in the far field.

摘要： A system and method for providing a substantially constant volume exhaust or ventilation air terminal system is shown for controlling exhaust and/or return airflow rates in a system having a central fan or ventilator. The system and method permits zone-by-zone or area-by-area airflow regulation or control in non-demand areas in response to a demand or call for ventilation in demand areas. In one embodiment, the system employs at least one constant airflow controller or regulator situated in a damper. In one embodiment, a terminal houses a plurality of sub-ducts each having an airflow regulator. At least one of the sub-ducts has a damper. When the damper is open, a maximum airflow through the terminal is a sum of maximum airflow permitted by the regulators.

摘要： An imaging catheter is provided having a distal end portion selectively rotatable relative to a catheter body. A transducer array is supported by the distal end portion so that a corresponding imaging field may be selectively panned about an axis extending distally from the catheter body. The catheter may be advanced within a patient to a desired location. Optionally, the catheter may then be steered, or curved to position the transducer array. Optionally, the catheter may be rotated to further position the transducer array. Then, the imaging field may be panned without manipulation of the catheter body.
