The image display method includes performing a position adjustment operation on an initial volume view in an image display interface to obtain at least one reference volume view, storing position information of the at least one reference volume view, and creating at least one label to point to the position information, the at least one label being displayed in the image display interface.

Apparatus and methods of use are provided for complex flow imaging and analysis that is non-invasive, accurate, and time-resolved. It is particularly useful in imaging of vascular flow with spatiotemporal fluctuations. This apparatus is an ultrasound-based framework called vector projectile imaging (VPI) that can dynamically render complex flow patterns over an imaging view at millisecond time resolution. The VPI apparatus and methods comprise: (i) high-frame-rate broad-view data acquisition (based on steered plane wave firings); (ii) flow vector estimation derived from multi-angle Doppler analysis (coupled with data regularization and least-squares fitting); and (iii) dynamic visualization of color-encoded vector projectiles (with flow speckles displayed as adjunct).

The processing circuitry estimates a position of a structure in a subject based on data obtained by scanning with respect to the subject and analyzes tissue characterization in the subject. The display circuitry displays an analysis result of the tissue characterization obtained by the processing circuitry with respect to a plurality of positions in the subject except for the estimated structure position.

An ultrasonic diagnostic apparatus is provided for allowing a displacement between a direction of an acoustic line of ultrasound and a direction of movement of biological tissue to be recognized. The apparatus includes a strain calculating section for calculating a strain in biological tissue based on two temporally different echo signals in an identical acoustic line acquired by an ultrasonic probe; an elasticity image data generating section for generating data for an elasticity image according to the strain calculated by the strain calculating section; a movement detecting section for detecting movement of the biological tissue in a B-mode image; an angle calculating section for calculating an angle between a direction of an acoustic line of ultrasound transmitted/received by the ultrasonic probe and a direction of movement of the biological tissue detected by the movement detecting section; and an image display processing section for displaying an indicator indicating the angle.

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.

Systems and methods for triggering the acquisition of elastography measurements based on motion data are disclosed. Motion data may be acquired by Doppler mode imaging in some embodiments. The motion data may be used to generate a trigger signal. The trigger signal may be provided to a transmit controller. The transmit controller may cause an ultrasound transducer to acquire elastography measurements responsive to the trigger signal.

An ultrasound system performs duplex colorflow and spectral Doppler imaging, with the spectral Doppler interrogation performed at a sample volume location shown on the colorflow image. The colorflow image is displayed in a color box overlaid on a co-registered B mode image. A color box position and steering angle processor analyzes the spatial Doppler data and automatically sets the color box angle and location over a blood vessel for optimal Doppler sensitivity and accuracy. The processor may also automatically set the flow angle correction cursor in alignment with the direction of flow. In a preferred embodiment these optimization adjustments are made automatically and continuously as a user pauses at points for Doppler measurements along a length of the blood vessel.

An ultrasound probe acquires a 3D image dataset of a volumetric region of the body. The 3D image data is reformatted into a sequence of successive parallel image planes extending in one of three orthogonal directions through the volume. The sequence of images is preferably formatted in accordance with the DICOM standard so that a clinician can review the 3D image data as a sequence of DICOM images on an image workstation.

Provided is an ultrasonic imaging apparatus capable of obtaining a more accurate shear wave elastic image by removing inefficient areas such as blood vessels using a shear wave observation signal in a section where an object is not affected by a push pulse, and a method for controlling the same. The ultrasonic imaging apparatus according to an embodiment includes: an ultrasonic probe configured to irradiate a push pulse to generate a shear wave to an object, irradiate a first observation signal to the object after the push pulse is irradiated, and irradiate a second observation signal to the object before the push pulse is irradiated or after the first observation signal is irradiated; a controller configured to determine an inefficiency region of the object based on displacement data for each region of the object obtained from the irradiated second observation signal, and generate a shear wave elastic image based on the determined inefficiency region and displacement data for each region of the object obtained from the irradiated first observation signal; and a display configured to display the generated shear wave elastic image.
