摘要： An ultrasonic diagnostic imaging system produces an image with an extended focal range by transmitting a plurality of beams spaced along an array for multiline reception. The receive multilines of a plurality of transmit beams are spatially aligned and are combined with phase adjustment between the respective receive multilines to prevent undesired phase cancellation. The combined multilines produce the effect of an extended transmit focus so that an image produced using the combined multilines exhibits an extended focal range. To prevent motion artifacts the multiline order is adjustable as a function of image motion.

摘要： An ultrasonic diagnostic imaging system transmits a plurality of focused beams normal to the plane of a transducer aperture and receives multiple receive lines in response to each transmitted beam. Sub-apertures of the transducer aperture are defined by apodization and signals of the sub-apertures are aligned and combined to produce signals exhibiting the effect of transmit steering at different angles with respect to the sub-apertures. The steered signals are detected and the detected signals relating to common points in an image field are combined. The combined detected signals are used to produce an ultrasound image with reduced speckle.

摘要： A vascular flow sensor assembly includes an ultrasound transducer (1-5) which is attached to the body by an adhesive or mechanical substrate to create acoustic coupling between the ultrasound transducer and the body. The assembly includes a force sensor (150) responsive to the attachment force which produces a signal representative of the force of attachment. The signal is detected by a monitoring instrument and used to alert a user to improper attachment of the vascular sensor. In an illustrated embodiment the signal actuates an indicator located on the sensor assembly.
