    摘要: A method and system for indicating the position and orientation of a scan plane relative to a patient is provided. The image as presented on a display is oriented in accordance with the orientation of a transducer. The orientation may provide for displaying an image where the transducer is not in a transducer up or transducer down position, but is rotated away from vertical of the display. Alternatively or additionally, a two or three-dimensional graphical generic representation is provided with a scan plane indicated as a polygon or image rendering within a generic representation to show relative positioning of the scan plane with respect to the patient.

    摘要: A catheter and method for determining a position of the catheter within the cardiovascular system is provided. Local bending and twisting is measured at multiple locations along the catheter. By integrating the measurements, the position and orientation of the catheter is determined. Based on the catheter position information, the location and orientation of an ultrasound transducer array connected with the catheter is known. The imaging array position and orientation information may be used to assist a physician in determining the tissue structure or fluid being scanned and/or assist in the accurate generation of three-dimensional representations.

    摘要: A system and related method for obtaining volumetric cardiac data of a subject. The data is generated by forming a plurality of focused ultrasound images corresponding to a series of ranges, generating myocardial boundary data for each of the plurality of ultrasound images, calculating the area of the region defined by said myocardial boundary data for each of the plurality of ultrasound images, multiplying the area for each of the plurality of ultrasound images by a slice depth corresponding to said ultrasound image to obtain the slice volume of each slice, and summing the slice volumes to obtain a total volume. In an alternative embodiment the system and related method combine an automated volumetric ultrasound system for finding chamber volumes and myocardial thicknesses, with a diagnostic electrocardiogram system to enable simultaneous diagnosis of mechanical and electrical cardiac problems.

    摘要: Images of the heart are formed by using multiple sets of ultrasound data. Each set of data is acquired and processed responsive to a different set of imaging parameters. The imaging parameter sets differ in at least one parameter, such as array position, temporal frequency response or transmit focal depth, so that the images formed using these data sets have, either laterally or axially, different spatial spectra. A set of images is formed responsive to a first imaging parameter set for a first cardiac cycle. Another set of images is formed responsive to a second imaging parameter set for a second cardiac cycle. The two sets of images are temporally aligned so that they correspond to the same set of phases of the cardiac cycle. Since the data acquisition and processing are distributed over multiple cycles of the motion, assuming regular periodic heart cycle, temporal resolution is maintained.

    摘要: A method and system for reducing speckle for two and three-dimensional images is disclosed. For two-dimensional imaging, a one and a half or a two-dimensional transducer is used to obtain sequential, parallel or related frames of elevation spaced data. The frames are compounded to derive a two-dimensional image. For three-dimensional imaging, various pluralities of two-dimensional frames of data spaced in elevation are compounded into one plurality of spaced two-dimensional frames of data. The frames of data are then used to derive a three dimensional set of data, such as by interpolation. Alternatively, the various pluralities are used to derive a three-dimensional set of data. An anisotropic filter is applied to the set of data. The anisotropic filter filters at least along the elevation dimension. In either situation, various displays may be generated from the final three-dimensional set of data. A method and system for adjustably generating two and three-dimensional representations is also disclosed. For three-dimensional imaging, at least two sets of three-dimensional data corresponding respectively to two types of Doppler or B-mode data are generated. The sets of data are then combined. An image or a quantity may be obtained from the combined data. By combining after generating the three-dimensional sets of data, the same data (sets of data) may be combined multiple times pursuant to different relationships. Thus, a user may optimize the image or quantity. Likewise, frames of data may be combined pursuant to different persistence parameters, such as different finite impulse response filter size and coefficients. The frames of data may then be re-combined pursuant to different persistence parameters. Original ultrasound data may also be used to re-generate an imaging using the same ultrasound image processes as used for a previous image.

    摘要: A method and system for identifying constrictions in a vessel are provided. Total blood volume flow is measured at various locations along the vessel. The total volume flow must be conserved. Regions with a different volume flow than expected (e.g. areas associated with a lower volume that violates conservation of flow) are identified as suspicious. Suspicious regions are likely associated with dropout artifact. Actual constrictions are determined from the geometry of images where the region is not suspicious.
