摘要： A VIBER vibrating mechanism (31) is coupled to a cannula or needle (30) and operates to provide flexural vibrations to move the needle (30) and to enable detection via the scanner (22) of the position of a needle within a body of interest by a color ultrasound imaging system (24) having a display (25). The VIBER mechanism exhibits multiple modes of oscillation when energized. The VIBER mechanism is excited to exhibit predetermined oscillations at a given frequency in the X-plane, a predetermined oscillation at another frequency in the Y-plane and another frequency of oscillation in the Z-plane. The frequency of oscillation is a function of the entire system, namely the VIBER mechanism and the tissue. The resonant frequency is preferred as it provides larger vibrational amplitudes. The vibration in the representative planes causes a typical conventional color ultrasound imaging system to display the vibration or movement by means of a color variation.
摘要翻译： VIBER振动机构（31）联接到套管或针（30）并且操作以提供弯曲振动以移动针（30）并且使得能够经由扫描器（22）检测针体内的针的位置由具有显示器（25）的彩色超声成像系统（24）感兴趣。 VIBER机构在通电时表现出多种振荡模式。激励VIBER机构在X平面中的给定频率，在Y平面中的另一频率处的预定振荡和Z平面中的另一振荡频率下呈现预定振荡。振荡频率是整个系统的函数，即VIBER机制和组织。谐振频率是优选的，因为它提供更大的振动振幅。代表性平面中的振动导致典型的常规彩色超声成像系统通过颜色变化来显示振动或运动。

摘要： An ultrasonic transducer (11) for use in locating devices with an ultrasonic ima ging system which is sensitive over a broad range or angles or incident acoustic beams such as those beams (14) emitted in u ltrasonic systems, has a curved surface (21), and is an annular member in shape. The elongated catheter (20) or other device passe s through the opening (22) of the annular transducer (11). Based on the shape of such transducers and the wavelength used. the respon se of the transducers is a function of the angle of the insonifying beam to the catheter axis (r). The particular response of such transducers is shown to depend on the curvature of the annular marker, with the radius of curvature chosen on the basis of the w avelength used in the ultrasonic scanning system between 2-50 wavelengths.

摘要： A VIBER vibrating mechanism is coupled to a cannula or needle and operates to provide flexural vibrations to move the needle and to enable detection of the position of a needle within a body of interest by a color ultrasound imaging system. The VIBER mechanism exhibits multiple modes of oscillation when energized. The VIBER mechanism is excited to exhibit predetermined oscillations at a given frequency in the X plane, a predetermined oscillation at another frequency in the Y plane and still another frequency of oscillation in the Z plane. In this manner, the VIBER mechanism device exhibits motion in all three planes, which motion is detectable by a conventional color ultrasound imaging system. The frequency of oscillation is a function of the entire system, namely the VIBER mechanism, the needle or cannula which is attached to the VIBER mechanism and the tissue. The resonant frequency is preferred as it provides larger vibrational amplitudes. In this manner, a resonant frequency is controlled by means of a feedback control loop, whereby the frequency applied to the VIBER mechanism is monitored to determine resonance and is held at the resonant frequency as the VIBER mechanism or needle is moved. The vibration in the representative planes causes a typical conventional color ultrasound imaging system to display the vibration or movement by means of a color variation. By viewing the display, a system operator, such as a physician can visualize the location of the needle because of the color indication provided by the display.
