Der Lebensweg als Bild der Geschichtlichkeitdiffuse, spatially incoherent ultrasound, as described by Havlice et a1., has made image content more reliable. Images of hand or foot displaying tendons and blood vessels are readily available and, at the moment, a first practical application will probably be in orthopedics.

https://doi.org/10.1007/978-3-642-85694-5cell. In particular conditions, an ultrasonic hologram can be “written” on a thin L.C. layer as a spatial modulation of the molecular orientation. Direct and real-time conversion to a visible hologram or image of the object can be achieved by means of . light. The system has inherent intensity or ph

über das Lachen, das Weinen und das G?hnensonic fields can be sampled with a more and more large apertures and a smaller and smaller sample interval. So the angular spectrum algorithm is becoming perfectly adapted to the field’s numerical reconstruction.

Sexualit?t, Sinnlichkeit und Pr?gung parenchyma, it can be used as the basis for clinical diagnosis. Several attempts have been made to relate B-scan image textures to disease states of soft tissue.. However, an alternative source of image texture is coherent acoustic interference, i.e. speckle, which is primarily a function of the im

Sexualit?t, Sinnlichkeit und Pr?gung be denied since this is proved by many experiments carried out on pure solutions of macromolecules. But these mechanisms do not justify the significant differences in attenuation measured in different tissues or the different pathological states of the same tissue.

über das Lachen, das Weinen und das G?hnenImages that purport to represent the distribution of scattering objects in living tissue can be generated from ultrasonic pulse-echo data by a number of means. In the simplest form, pulses are transmitted and received on a single fixed-focus transducer that is scanned mechanically or by hand to generate a conventional B-scan image.
