The present invention relates to an apparatus for tracking a position of an interventional device respective an image plane of an ultrasound field. The position includes an out-of-plane distance (Dop). A geometry-providing unit (GPU) includes a plurality of transducer-to-distal-end lengths (Ltde.sub.1 . . . n), each length corresponding to a predetermined distance (Ltde) between a distal end of an interventional device and an ultrasound detector attached to the interventional device, for each of a plurality of interventional device types (T.sub.1 . . . n). An image fusion unit (IFU) receives data indicative of the type (T) of the interventional device being tracked; and based on the type (T): selects from the geometry-providing unit (GPU), a corresponding transducer-to-distal-end length (Ltde); and indicates in a reconstructed ultrasound image (RUI) both the out-of-plane distance (Dop) and the transducer-to-distal-end length (Ltde) for the interventional device within the ultrasound field.

To register a position and an angle of a scanning surface of an ultrasound probe easily and accurately. A phantom including two or more wires stretched in a non-parallel manner is disposed in a real space in which a position detection sensor is disposed. An ultrasound probe, to which a probe position detection marker is attached, is moved on the phantom in a parallel manner while keeping an orientation of a main plane of the ultrasound probe constant. Two or more ultrasound images of the phantom are acquired while detecting a position of the probe position detection marker in the real space with the position detection sensor. Positions of cross-sectional images of the two or more wires included in each of the two or more ultrasound images are obtained. A relation between the position of the probe position detection marker in the real space and orientations and positions of the captured ultrasound images in the real space is calculated based on a relation between the obtained positions of the cross-sectional images. The calculated relation as probe coordinate transformation information is registered in a storage unit.

For clutter reduction in ultrasound elasticity imaging, the contribution of clutter to different frequency components (e.g., the transmit fundamental and the propagation generated second harmonic) is different. As a result, a difference in displacements determined at the different frequency bands is used to reduce clutter contribution to displacements used for elasticity imaging.

An analysis apparatus includes processing circuitry configured to obtain quantitative values of a plurality of types of tissue properties relating to a region of interest of a subject, and generate a diagram of the region of interest based on the quantitative values.

An ultrasonic diagnostic imaging system is used to measure volume flow. An ultrasound probe operating in the biplane mode is used to acquire a vessel in a long axis view in a first Doppler image, and simultaneously in a transverse view in a second Doppler image. Volume flow is calculated from the transverse view of the vessel. The plane of the second image is aligned with the Doppler angle of the first image so that angle correction determined for the first image can be used for angle correction in the volume flow calculation.

An ultrasound diagnostic system (1) includes an ultrasound probe (2), a handheld type diagnostic apparatus main body (3), and a remote apparatus (4), the ultrasound probe (2) includes a position sensor (14) that detects a measurement position of the ultrasound probe (2), the diagnostic apparatus main body (3) includes an image generation unit (22) that generates an ultrasound image and a monitor (24), the remote apparatus (4) includes an organ detection unit (32) that detects an organ of a subject by analyzing the ultrasound image, a score of the measurement position with respect to an optimum position in a case of measuring the organ detected by the organ detection unit (32) by the ultrasound probe (2) is input to the remote apparatus (4) and is transmitted from the remote apparatus (4) to the diagnostic apparatus main body (3) to be displayed on the monitor (24).

Disclosed is a method for displaying an ultrasonic image, comprising the steps of: identifying a lesion area included in an ultrasonic image; diagnosing the lesion area to obtain a diagnostic result; generating a diagnostic image by displaying, in the lesion area of the ultrasonic image, a first area which is at least one area on which the lesion is diagnosed; and displaying a user interface screen including the diagnostic image and the diagnostic result.

An imaging system comprises an ultrasounds probe (102) including a housing (108) with a probe orientation marker (116) disposed on the housing. The imaging system further comprises a display (132). The imaging system further comprises a console (104), electrically interfaced with the probe and the display, that includes a controller (128). The controller is configured to visually present an ultrasound image, in electronic format and via the display, with an image orientation marker visually displayed superimposed over the image and selectively located with respect to the displayed image based on the location of the probe orientation marker on the housing.

Disclosed is a method of changing at least one of a direction and position of a plane selection line for acquiring an image of a plane of interest of an object. The method includes acquiring a medical image of an object, displaying a first plane image acquired along a first plane selection line of the medical image, setting a pattern which is used to change at least one of the direction and position of the plane selection line, changing at least one of the direction and position of the plane selection line, based on the set pattern, and displaying a second plane image acquired along the changed plane selection line.
