摘要： A system for identifying tissue includes a subject-specific tissue signature (48) derived from an ultrasound image. The tissue signature has specified ranges of characteristics based on analysis of a reference tissue of a subject having a confirmed pathology. A searching module (140) is stored in memory and is configured to search through images (134) for a volume of the subject to identify tissues in the images for comparison. A comparison module (124) configured to identify tissue matches between the tissue signature of the reference tissue and the tissue signature of the tissues in the volume in accordance with a score based upon the specified ranges of characteristics.

摘要： A method for ablation treatment using ultrasound data begins by identifying pathology to be treated and one or more blood vessels proximate the treatment site in a medical diagnostic image. The identified ROI and the blood vessels are automatically indicated in an ultrasound image Ultrasonic Doppler velocity data is acquired from the flow within the vessels and the Doppler data is used to calculate the volume blood flow through the vessels. The thermal effect of the heat transported by this blood flow is considered in the planning or conduct of the ablation treatment, as by modifying the size of a burn zone graphic around the tip of the ablation probe.

摘要： An ultrasound system is used to measure the percent stenosis of a vessel in terms of residual lumen area. A measurement of volume blood flow is made at an unobstructed point of the vessel near the site of the stenosis. A measurement of the time averaged mean blood flow velocity is made at the stenosis. The quotient of these two values is computed to produce an estimate of the residual lumen area and the percent stenosis at site of the obstruction.

摘要： An ultrasonic diagnostic imaging system is used to measure volume flow. An ultrasound probe operating in the biplane mode is used to acquire a vessel in a long axis view in a first Doppler image, and simultaneously in a transverse view in a second Doppler image. Volume flow is calculated from the transverse view of the vessel. The plane of the second image is aligned with the Doppler angle of the first image so that angle correction determined for the first image can be used for angle correction in the volume flow calculation.

摘要： An ultrasound system includes a 3D imaging probe and a needle guide which attaches to the probe for guidance of needle insertion into a volumetric region which can be scanned by the 3D imaging probe. The needle guide responds to the insertion of a needle through the guide by identifying a plane for scanning by the probe which is the insertion plane through which the needle will pass during insertion. The orientation of the insertion plane is communicated to the probe to cause the probe to scan the identified plane and produce images of the needle as it travels through the insertion plane.

摘要： An ultrasound system and method are described for acquiring standard views of the fetal heart simultaneously with real-time imaging. A matrix array probe is manipulated until a first standard view such as a 4-chamber view is acquired. The first standard view image is matched to its corresponding plane in a fetal heart model. From the matched plane of the heart model, the orientations of the other standard views are known from the geometrical relationships of structures within the heart model. This orientation information is used to control the matrix array probe to automatically scan the planes of all of the standard views simultaneously in real-time.

摘要： An ultrasound system with a matrix array (500) probe (10) operable in the biplane mode is used to assess stenosis of a blood vessel by simultaneously displaying two color Doppler biplane images (60a, 60b) of the vessel, one a longitudinal cross-sectional view (60a) and the other a transverse cross-sectional view (60b). The two image planes intersect along a Doppler beam line (68) used for PW Doppler. A sample volume graphic (SV) is positioned over the blood vessel at the peak velocity location in one image, then positioned over the blood vessel at the peak velocity location in the other image. As the sample volume location is moved in one image, the plane and/or sample volume location of the other image is adjusted correspondingly. Spectral Doppler data (62) is then acquired and displayed from the sample volume location.
