摘要： An ultrasonic transducer probe is provided, in which the transducer is oscillated by a crank shaft for sector scanning. The crank shaft is driven by a motor having a moving magnet stack assembly in a tubular set of electromagnetic coils. The motor also moves a bimetallic pin through a position sensor coil so that the position of the transducer is represented by the detected inductance change of the coil.

摘要： An ultrasonic transducer assembly and system including a disc-shaped transducer element surrounded by ring-shaped transducer elements of different width to permit dynamic focusing and minimum phase cancellation. The elements are switched so that the output signals for various depths have a small dynamic range whereby the dynamic range of associated amplifiers is significantly reduced.

摘要： Echo data relating to the distance away of reflective elements of an object surface is received by an array of receivers. A signal processing device receives the data and together with information as to the range of the object surface defines equitime loci of the object surface corresponding to the data. Image elements are displayed at positions in an image plane corresponding to the intersections of the equitime loci.

摘要： An ultrasonic probe has a housing, a base pivotally mounted within the housing, an extension formed upon the base, and a scanning ultrasonic transducer disposed upon the distal end of the extension. The extension is preferably configured such that the scanning transducer moves along an arc of approximately 50 degrees having a radius of approximately 40 mm and is thus suitable for imaging elongate anatomical structures such as portions of the peripheral vascular system. A doppler ultrasonic transducer optionally fixedly disposed within the housing proximate the scanning ultrasonic transducer measures fluid flow within the elongate anatomical structure. The doppler ultrasonic transducer is disposed at one end of the arc along which the scanning ultrasonic transducer travels such that the radiation path of the doppler ultrasonic transducer is periodically obscured by the scanning ultrasonic transducer. The doppler ultrasonic transducer measures fluid flow through the elongate anatomical structure when the scanning ultrasonic transducer is not within the radiation path of the doppler ultrasonic transducer.

摘要： An ultrasonic probe has an elongate tubular member and an imaging ultrasonic transducer pivotally mounted proximate the distal end of the tubular member. Reciprocating pivotal motion of the ultrasonic transducer is effected to facilitate scanning. A first cable attached to the imaging ultrasonic transducer effects pivoting thereof in a first direction and a second cable attached to the imaging ultrasonic transducer effects pivoting thereof in a second direction. A linear motor is attached to the first cable for pulling the first cable to effect pivoting of the ultrasonic transducer in the first direction and a tension means is attached to the second cable for pulling the second cable when the linear motor ceases pulling the first cable to effect pivoting of the ultrasonic transducer in the second direction.

摘要： A transducer is pivoted by a linear motor having an electrical coil as the reciprocally moving member. The coil is in a plane orthogonal to the lines of magnetic flux between opposed permanent magnets of opposite polarity affixed to the probe case, providing efficiency. A mechanical linkage between the linear motor electrical coil moving member and the transducer which is forced in pivoting motion transmits only axial force, and not torque, by employing a ball and socket joint at one end of a crankshaft. Electrical connections to the electrical coil are facilitated through springs which additionally mechanically bias the reciprocal movement of the coil. Electrical connections to the pivoting transducer are facilitated through a helical coil wrapping the pivot shaft. These electrical connections accomodate mechanical motions within the probe. A bellows-fold cylindrical air bladder is positioned within the fluid chamber of the probe to allow for thermally-induced changes in fluid volume.

摘要： An ultrasonic prostate probe assembly is disclosed, characterized by the ultrasonic transducer being carried upon a gimbal cup which is rotatably mounted to the probe assembly to allow selection of multiple sector scan directions during operation of the probe. The transducer is pivoted via a spring biased cable linkage connected to a linear motor having an electric coil as the reciprocating moving member. Selective rotation of the gimbal cup is effectuated by manipulation of an additional cable linkage extending axially through the probe assembly. The use of multiple sector scan directions allows improved identification and sizing of problematic body tissue in applications such as prostate applications where space constraints prevent manipulation of the probe into differing scanning positions.

摘要： An ultrasonic transducer probe is provided which utilizes a pivoting transducer to perform an ultrasonic sector scan. The transducer and its drive mechanisms are contained within a fluid chamber. A portion of the wall of the fluid chamber includes a flexible bellows, which expands and contracts as pressure and temperature changes alter the fluid volume, thereby altering the fluid chamber volume.

摘要： An ultrasonic transducer is disclosed comprising a transducer head assembly containing a movable crystal holder containing a crystal which is coupled to a stationary base by mechanical linkage means. A motor adapted to provide linear reciprocating motion is coupled to the mechanical linkage means for causing the crystal holder and crystal, when driven by the motor, to undergo reciprocating swinging motion for transmitting ultrasonic energy to and receiving echo signals from an object in front of the transducer in a sector scanning manner.
