    • An ultrasound system and method for intravascular ultrasonic imaging includes an array of beacons that are fixed to direct ultrasonic energy toward an imaging transducer, with individual beacons being identifiable in order to determine the angular position of the imaging transducer. Based upon the data related to beacon identification, operation of the imaging device is adaptively adjusted in order to compensate for variations in angular velocity of the transducer. Adaptive compensation may be performed by adjusting the pulse repetition rate of transmitted ultrasonic energy, by adjusting the scan conversion algorithm or mapping reflected ultrasonic energy, or by varying control of the drive structure for rotating the transducer. The beacons are preferably piezoelectrically active, but passive beacons may also be used. Position identification may be performed by techniques including amplitude sensing, phase sensing, pulse length sensing, and frequency sensing. As an alternative to rotation of the transducer, ultrasonic signals may be formed at a proximal end of a probe and then conducting the energy to the distal end via a waveguide.
    • 用于血管内超声成像的超声系统和方法包括固定以朝向成像换能器直接超声能量的信标阵列,其中各个信标是可识别的,以便确定成像换能器的角位置。 基于与信标识别相关的数据,自适应地调整成像装置的操作,以补偿换能器的角速度的变化。 可以通过调整扫描转换算法或映射反射的超声能量,或者通过改变用于旋转传感器的驱动结构的控制来调节发射的超声能量的脉冲重复率来执行自适应补偿。 信标优选地是压电有源的,但也可以使用被动信标。 可以通过包括幅度感测,相位感测,脉冲长度感测和频率感测的技术来执行位置识别。 作为换能器旋转的替代方案,可以在探针的近端处形成超声波信号,然后经由波导将能量传导到远端。

    • An ultrasonic probe for imaging tissues from inside a patient's body cavity is disclosed. The ultrasonic probe includes a housing near to the probe's distal end, an ultrasonic beam emitting assembly having a pivotable part, and a driver for producing a pivotal motion on the pivotable part. The housing has a portion that is acoustically transparent. The pivotable part is movable and is operatively connected to the housing. The pivotable part can either have mounted on it a transducer for emitting ultrasound or a reflector for reflecting ultrasound. In either case, when the pivotable part pivots it sweeps ultrasonic energy over a selected angle. The driver is located near to the transducer such that all driving motions for driving the pivotal motion occur near the distal end of the ultrasonic probe.
