摘要： A method to measure spatial fluid flow components and their velocity profiles in a number of locations in a cross-sectional area of a lumen or other body cavity by using ultrasound in which the cross-sectional area is interrogated by a plurality of ultrasonic beams; the estimation of the spatial flow components is obtained from a combination of estimations of axial, lateral and total flow; the estimation of one or more flow components is obtained through any combination of time-shift and decorrelation analysis of two or more beam-signals of the interrogating ultrasound transducer; and the estimation accuracy is further improved by the use of a reference decorrelation curve obtained from experiments or beam-theory or both.

摘要： Catheter assembly and method in which an imaging transducer is positioned proximally of a treatment device at the distal end of a catheter. Unrestricted flow between a fluid lumen in the catheter and the treatment device is provided by an annular passageway formed between the walls of a marker tube which extends through the transducer and a guide wire tube which passes through the marker tube, and by a plenum chamber which is formed between the distal end of the catheter and the proximal end of the marker tube in communication with the fluid lumen and the flow passageway. The catheter, the treatment device, and the transducer are all constructed as individual modular units which can be assembled together as desired to form the assembly.

摘要： L'invention se rapporte à un appareil et à un procédé qui permettent de représenter en images des petites cavités du corps humain et dans lesquels des formes d'ondes de référence, destinées à être utilisées pour produire une image améliorée, sont générées in vivo plutôt qu'in vitro comme c'est le cas dans les techniques classiques. Ces formes d'ondes de référence sont utilisées pour débarrasser les signaux d'imagerie des bruits parasites qui sont à l'origine des artefacts apparaissant dans les images générées à partir de ces signaux. La sonde d'imagerie de l'appareil est à cet effet d'abord introduite dans une première zone du système vasculaire devant être représenté en image et les formes d'ondes de référence sont recueillies. Une fois terminée cette opération de collecte des formes d'ondes de référence, la sonde d'imagerie est introduite plus avant dans le système vasculaire jusqu'à une seconde zone devant être représentée en images. Si de nouvelles formes d'ondes de référence sont requises, la sonde d'imagerie est simplement retirée de la première zone du système vasculaire ou de nouvelles formes d'onde de référence sont recueillies, puis la sonde d'imagerie est à nouveau introduite plus avant dans la seconde zone, qui doit être représentée en images. La présente invention décrit également un appareil d'imagerie capable de prendre des images de la région proche de la surface de la sonde et qui, à cet égard, élimine les artefacts dans les formes d'ondes d'imagerie qui habituellement forment une couronne dans l'image visualisée de la région se trouvant au périmètre de la sonde.

摘要： A blood flow detection and imaging method and system is described for displaying images in accordance with signals transmitted from an intravascular ultrasound transducer probe. The image processor includes means for independently designating persistence factors for smoothing calculated speed and power of the dynamic portion of a field of view within a vasculature. Furthermore, the designation of a particular image point within a field of view as a dynamic image point (such as a blood flow region) as opposed to a static image point (such as a tissue region) is determined by averaging signal values for image points proximate to an image point of interest over both time and space.

摘要： An ultrasound transducer assembly of the present invention includes a flexible circuit to which an ultrasound transducer array and integrated circuitry are attached during fabrication of the ultrasound transducer assembly. Integrated circuitry and transducer elements are attached to the flexible circuit while the flexible circuit is in a substantially flat shape. The contacts of the transducer elements are positioned on substantially the same plane such that electrical contact with signal and ground lines on the flexible circuit is established without the need for conductive bridges to physically remote electrodes. In an embodiment of the invention wherein the transducer elements are arranged in a cylindrical array, gaps are entirely filled with backing material having a relatively low acoustic impedance. Structure integrity is enhanced and a path to ground facilitated by electrically conductive disks attached to the ends of the transducer assembly.

摘要： An apparatus and method are described for imaging blood flow from within a vasculature. An ultrasound catheter probe (20) carrying an ultrasound transducer array (24) is inserted within a blood vessel (14). The transducer array emits ultrasound excitation signals and receives ultrasound echo waveforms reflected from blood and tissue in a region of the vasculature. A series of the echo waveforms resulting from a series of excitation signals are combined in a manner such that the echo signals from static features in the region, such as tissue and plaque (12), are significantly attenuated. The combined signal primarily represents the relatively dynamic features in the region (i.e., the blood flow). A blood flow image is constructed from the combined signal. The blood flow image is colored and combined with an image of the relatively static features in the region. Thereafter the combined image is displayed on a video display (28).

摘要： A dilating and imaging apparatus (10) for attaching to and receiving pressurized fluid from a distal end of a catheter. The apparatus includes an inflatable balloon (18) and an imaging device (44) positioned behind an expandable portion of the balloon and upstream of the flow of pressurized fluid into the balloon so as to enable the balloon to deflate and achieve a smaller diameter than that of the imaging device (44), thus enabling the apparatus to enter a stenosis having a smaller diameter than the imaging device. In one embodiment of the invention, the imaging device can be maneuvered within the balloon while the balloon is inflated and dilating the stenosis.

摘要： An ultrasound catheter is disclosed for providing substantially real-time images of small cavities. The ultrasound catheter is characterized by separate and distinct materials for backing the transducers and for carrying the electronics components. The separate materials comprise an electronics carrier meeting the requirements for holding the integrated circuitry of the ultrasound device and a backing material displaying superior characteristics relating to reducing ringing and minimizing the effect of other sources of signal degradation in the transducer assembly. Also, in accordance with the present invention, a technique is described for connecting the conductor lines of the separate transducer assembly and electronics body.
