An ultrasonic diagnosis apparatus according to an embodiment includes a transmission unit, a reception unit, a generator, and a display controller. The transmission unit causes an ultrasonic probe to transmit a displacement-producing ultrasonic wave and causes the probe to transmit a displacement-observing ultrasonic wave. The reception unit generates reflected-wave data based on a reflected wave received by the probe. The generator calculates displacement at each of a plurality of positions in the scan area over a plurality of time phases, based on the reflected-wave data, determines a time phase when the calculated displacement is substantially maximum, for each of the positions, and generates image data representing positions where the determined time phases are substantially the same as each other, among the positions. The display controller superimposes an image based on the image data on a medical image corresponding to an area including the scan area.

Aspects of the technology described herein relate to instructing an operator to move an ultrasound device along a predetermined path relative to an anatomical area in order to collect first ultrasound data and second ultrasound data, the first ultrasound data capable of being transformed into an ultrasound image of a target anatomical view, and the second ultrasound data not capable of being transformed into the ultrasound image of the target anatomical view.

A steerable multi-plane ultrasound imaging system (MPUIS) for steering a plurality of intersecting image planes (PL.sub.1 . . . n) of a beamforming ultrasound imaging probe (BUIP) based on ultrasound signals transmitted between the beamforming ultrasound imaging probe (BUIP) and an ultrasound transducer (S) disposed within a field of view (FOV) of the probe (BUIP). An ultrasound tracking system (UTS) causes the beamforming ultrasound imaging probe (BUIP) to adjust an orientation of the first image plane (PL.sub.1) such that a first image plane passes through a position (POS) of the ultrasound transducer (S) by maximizing a magnitude of ultrasound signals transmitted between the beamforming ultrasound imaging probe (BUIP) and the ultrasound transducer (S). An orientation of a second image plane (PL.sub.2) is adjusted such that an intersection (AZ) between the first image plane and the second image plane passes through the position of the ultrasound transducer (S).

2019PF00643 32 ABSTRACT Disclosed is an ultrasound roadmap image generation system. The system includes a processor configured for communication with an ultrasound imaging device that is movable relative to a patient. The processor receives a first bi-plane or 3D image representative of a first volume within the patient and a second bi-plane or 3D image representative of a second volume within the patient. The processor then registers the first bi-plane or 3D image and the second bi-plane or 3D image to determine the motion between the first bi-plane or 3D image and the second bi-plane or 3D image. The processor then generates a 2D roadmap image of a region of interest by combining the first bi-plane or 3D image and the second bi-plane or 3D image, based on the determined motion; and outputs a screen display comprising the 2D roadmap image.

A 3D ultrasonic diagnostic imaging system produces 3D display images at a 3D frame rate of display which is equal to the acquisition rate of a 3D image dataset. The volumetric region being imaged is sparsely sub-sampled by separated scanning beams. Spatial locations between the beams are filled in with interpolated values or interleaved with acquired data values from other 3D scanning intervals depending upon the existence of motion in the image field. A plurality of different beam scanning patterns are used, different ones of which have different spatial locations where beams are located and beams are omitted. In a preferred embodiment the determination of motion and the consequent decision to use interpolated or interleaved data for display is determined on a pixel-by-pixel basis.
