Embodiment Construction

[0015] first reference figure 1 , an ultrasound probe 10 capable of three-dimensional imaging includes a two-dimensional array transducer 12 that transmits electronically steered and focused beams over a volumetric region and receives a single or multiple receive beams in response to each transmitted beam . Groups of adjacent transducer elements called "patches" or "sub-arrays" are collectively manipulated by a microbeamformer (μBF) in probe 12, which performs Partial beamforming, thereby reducing the number of conductors in the cable between the probe and the main system. Suitable two-dimensional arrays are described in US Pat. No. 6,419,633 (Robinson et al.) and US Pat. No. 6,368,281 (Solomon et al.). US Patents US 5997479 (Savord et al.) and US 6013032 (Savord) describe microbeamformers. The transmit beam characteristics of the array are controlled by a beam launcher 16 which causes the apodized aperture elements of the array to launch a focused beam of desired width in ...

Abstract

A 3D ultrasonic diagnostic imaging system produces 3D cardiac images at a 3D frame rate of display which is equal to the acquisition rate of a 3D image dataset. The volumetric cardiac 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. A sequence of different beam scanline patterns may be continuously repeated, or the patterns of the sequence synchronized with the cardiac phases such that, over a sequence of N heartbeats, the same respective phase is scanned by N different scanline patterns.

Description

technical field [0001] The present invention relates to medical diagnostic ultrasound systems, and in particular, to ultrasound systems that perform real-time 3D imaging of the heart at high display frame rates. Background technique [0002] Ultrasound imaging has been used for many years to scan and display two-dimensional (2D) image planes of the body in real time. Real-time 3D imaging has become commercially available in recent years with the advent of matrix transducer arrays and ultrasound probes that use 2D transducer arrays to electronically scan volumetric regions of the body. An obstacle to real-time 3D imaging is the time required to scan volumetric regions. A typical 2D image plane can be scanned by 128 transmit and receive scan lines to form a 2D image. Even at the maximum diagnostic depth, the velocity at which ultrasound travels through the body, nominally 1580 m / s, enables acquisition of images fast enough for real-time imaging. Real-time imaging generally ...
