20080294048 | Ultrasonic Diagnosis of Myocardial Synchronization - An ultrasonic diagnostic imaging method and system are described for detecting abnormalities in the synchronicity of heart wall stimulation. Points on opposite sides of a chamber of the heart are identified in a starting ultrasound image, then tracked through at least a portion of the heart cycle. The changing positions of lines extending between pairs of the points are accumulated and displayed in a color kinesis display in which each color depicts the location of a line at a particular point in the cardiac cycle. In an illustrated example the points are tracked through the cardiac cycle by speckle tracking of the speckle pattern of the adjacent myocardial tissue, tracking specific anatomy, or tracking tissue texture. | 11-27-2008 |
20090030313 | Three Dimensional Diagnostic Ultrasonic Image Display - A three dimensional ultrasonic imaging system acquires 3D image data from a volumetric region and processes the image data to produce a live 3D image of the volumetric region, a 2D image of a face or a central cut plane of the volumetric region, and a 2D image of a cut plane which is orthogonal to the plane of the first 2D image. The two 2D images enable the user to quickly orient the position of the anatomy shown in 3D in the live 3D image. | 01-29-2009 |
20090118616 | Three Dimensional Ultrasonic Scanning With a Steerable Volumetric Region - A three dimensional ultrasonic imaging system produces a live steerable 3D image of a volumetric region of a subject. The system includes a user control which is continuously adjustable by a user to sweep the displayed 3D volume between the limits of left and right beam steering angles of an electronically steered matrix array transducer. | 05-07-2009 |
20090149757 | Three Dimensional Ultrasonic Scanning With Live Subvolumes - A three dimensional ultrasonic imaging system includes a matrix array transducer which is capable of scanning beams over a maximal volumetric region. The array transducer is operable to selectively scan one of a plurality of subvolumes of the maximal volumetric region at a real time scanning rate such that a live 3D image of the subvolume is processed and displayed. A user control is actuated to step the system through the scanning of a sequence different subvolumes. In an illustrated embodiment the maximal volumetric region encompasses the heart, and the system can be stepped through the scanning and display of live 3D images of front, center, and back subvolumes of the heart. | 06-11-2009 |
20090156935 | Three Dimensional Diagnostic Ultrasound Imaging System with Image Reversal and Inversion - A three dimensional ultrasonic imaging system acquires 3D image data from a volumetric region and processes the image data to produce a live 3D image of the volumetric region in a given orientation. A user control can be switched by a user to present the image in a different orientation if desired. Both the anatomy in the 3D image and the image format can be inverted, and the left-right appearance of the 3D image can be reversed with a corresponding front-back reversal of the anatomy. | 06-18-2009 |
20130066206 | HIGH VOLUME RATE 3D ULTRASOUNIC DIAGNOSTIC IMAGING - 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. | 03-14-2013 |
20130066207 | HIGH VOLUME RATE 3D ULTRASONIC DIAGNOSTIC IMAGING OF THE HEART - 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. | 03-14-2013 |
20140358004 | SIMULTANEOUS ULTRASONIC VIEWING OF 3D VOLUME FROM MULTIPLE DIRECTIONS - An ultrasonic diagnostic imaging system scans a volumetric region of a body. A clinician defines a three dimensional region of interest within the volumetric region. The three dimensional region of interest is viewed from two different viewing directions to give the clinician a sense of the structure, makeup, and orientation of the region of interest. The three dimensional region of interest can be viewed from viewing directions in 180° opposition to each other, orthogonal, or at an intermediate angle. Manipulation of one view of the three dimensional region of interest causes both views to change, as if the clinician were manipulating both views simultaneously in the same way. | 12-04-2014 |
