摘要： The ultrasound transducer array defines an average row spacing along the elevation for receiving transducer elements that differs from an average row spacing along the elevation for transmitting transducer elements. In one embodiment a relatively "coarse" row spacing is used for reception and a relatively "fine" row spacing is used for transmission. The differing spacings lead to different transmit-elevation and receive-elevation beam-patterns. In one configuration the number of transducer elements, and correspondingly the number of ultrasound processing channels, is reduced. In an alternative configuration the beam-pattern "footprint" is increased without increasing the number of transducer elements or processing channels. The array includes dedicated transmit-only elements and/or dedicated receive-only elements, together with coincident, time-shared transmit/receive elements. The coarse-fine spacings enable improved elevational focus without substantially increasing side lobe levels in a focal plane and far field portion of a resulting beam-pattern.

摘要： An auscultation system aids a clinician's diagnosis of the heart sounds by visually displaying at least an S1 heart sound and an S2 heart sound, and ascertaining an onset of at least one of the heart sounds. A corresponding audio representation of the heart sounds can be provided to the clinician. The auscultation system includes a sensor for sensing heart sounds from at least one chest location of the patient and for transducing the heart sounds into electrical signals. The auscultation system also includes a signal processor for selectively filtering the electrical signals thereby highlighting frequency differences of the heart sounds, and further includes a video display for selectively displaying the selectively filtered electrical heart signals. In some embodiments, the auscultation system also displays calipers corresponding to the time domain and the frequency domain of the heart sounds, permitting the clinician to zoom in and out portions of the heart sounds of particular interest and also to take more accurate measurements of these portions of the heart sounds.

摘要： Methods and apparatus for non-uniform rotation distortion detection for enhanced intravascular ultrasound imaging. The present invention provides methods and apparatus which detect non-uniform rotation in an improved manner without using beacons which may create shadowing of tissue behind the beacons or other undesired artifacts in the image. In specific embodiments, the present invention may provide a particularly simple and useful solution for addressing the problem of non-uniform rotation distortion in intravascular ultrasound imaging in systems which use mechanical scanning. In specific embodiments, the present invention utilizes correlation of received signals in an image vector from reverberating ultrasound in a bubbly liquid-flushed catheter to determine non-uniform rotation of the transducer within the catheter. In other embodiments, the present invention utilizes correlation of imaging vectors within a blood speckle region given a particular beamwidth of ultrasound energy from a transducer to determine non-uniform rotation of the transducer.
