摘要： A sputtering target (24) under test is irradiated with an ultrasonic pulse (20). The ultrasonic pulse (20) has a wavelength in the sputtering target (24) in the range of the average grain size for the target (24) under test. Backscattering echoes (28) are produced by the interaction of the pulse (20) with grain boundaries in the target (24) under test. The backscattering echoes (28) are detected and a representative electrical signal is generated. The number of occurrences of the backscattering echoes (28) having amplitudes within predetermined ranges are determined. A histogram of the number of occurrences versus amplitude is plotted. The histogram for the target (24) under test is compared with reference histograms for sputtering targets having known crystallographic orientations to determine the texture of the target (24) under test.

摘要： Temporal variations in backscatter from an ultrasound contrast agent located in the vascular system and induced by movement of the scatterers are used to visualise the presence of contrast agent by determining areas where correlation between successive ultrasound images is poor. This low level of correlation arising from intravascular contrast agent movement permits distinction between stationary bulk tissue and moving bulk tissue since movement of the latter solid tissue scatterers is correlated.

摘要： A process for forming the image of a spatially fixed object uses a primary (wave) radiation, in particular ultrasonic radiation, directed towards the object. The image formation is carried out by means of echo signals received by an echo signal receiver, on the basis of their propagation time and/or amplitude with respect to an axis of the object oriented in the direction in space of the primary radiation. The object (1) is located between the primary radiation emitter/echo signal receiver (2) and a reference surface (6) oriented perpendicularly to the direction (5) in space of the primary radiation (3) and which reflects the primary radiation (3) as an echo signal (4) more strongly than other areas of the object located in the field of representation. The mean or expected propagation time and/or amplitude of an echo signal (4') from the primary radiation (3') which passes through the object (1), is reflected by the reference surface (6) and received by the primary radiation emitter/echo signal receiver (2), is determined or predetermined as a reference signal. The propagation time and/or amplitude of an echo signal (4) from the primary radiation (3) which passes through the object (1), is reflected by the reference surface (6) and received by the primary radiation emitter/echo signal receiver (2), is determined, and the deviation between the echo signal (4) reflected by the reference surface (6) and the reference signal is evaluated.

摘要： Echo signals obtained from a range zone (BZ) opposite a focal point (F) are processed by processor (38) and supplied to hold circuit (60) to provide an image pixel signal value. A compensation pixel signal value for hold circuit (64) is obtained by repeating the transmitting-receiving operation using a beam which is unfocused at any point along the beam axis between the transducer (10) and backscatter zone (BZ). The image and compensation pixel signals from hold circuits (60) and (64) are combined at combiner (68) to provide for a compensated image pixel signal output from the combiner. Artifacts which otherwise would result from non-uniform reflective properties of the backscatter zone (BZ) are removed by this process. Compensated image pixel signals are displayed at display (72).

摘要： A method is disclosed for determining a flow acceleration directly from beamformed ultrasound data, i.e. independent of velocity estimates. The method includes extracting data from two different times and a same position, or two different positions and a same time, from the beamformed ultrasound data, and producing cross- correlation data to directly estimate the flow acceleration. The flow acceleration estimate may be processed to derive information for analyzing ventricular performance, studying hemodynamics or estimating pressure gradients in the circulatory system. An apparatus includes a beamformer (112) configured to process electrical signals indicative of received echoes produced in response to an interaction of a transmitted ultrasound signal with tissue and generate RF data, and an acceleration flow processor (114) configured to directly process the RF data and generate a flow acceleration therefrom.
