Abstract

An ultrasound imaging system (100) includes at least first and second arrays (108) of transducer elements, which are angularly offset from each other in a same plane. Transmit circuitry (112) excites the first and second arrays to concurrently transmit over a plurality of angles. Receive circuitry (114) controls the first and second arrays to concurrently receive echo signals over the plurality of angles. An echo processor (116) processes the received signals, producing a first data stream for the first array and a second data stream for the second array. The first and second data streams include digitized representations of the received echo signals. A sample matcher (118) compares samples of the first and second data streams and determines a cross-correlation there between. A correlation factor generator (120) that generates a correlation factor signal based on the determined cross-correlation. A scan converter (122) generates a 3D image for display based on the correlation factor signal and the first and second data streams.

Description

technical field [0001] The following generally relates to ultrasound imaging, and more particularly to an ultrasound imaging apparatus configured for three-dimensional (3D) and / or four-dimensional (4D) ultrasound imaging. Background technique [0002] Ultrasound imaging systems provide useful information about the internal properties of the object under examination. An exemplary ultrasound imaging system has included an ultrasound probe having a transducer array and a console. The ultrasound probe houses the transducer array including one or more transducer elements. The console includes a display monitor and a user interface. [0003] The transducer array transmits ultrasound signals into the field of view and receives echoes generated in response to the signals interacting with structures therein. The received echoes are processed to produce an image of the scanned structure. These images can be visually presented through a display monitor. Depending on the configurat...
