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.

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

However, an alternative source of image texture is coherent acoustic interference, i.e. speckle, which is primarily a function of the im

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 GähnenImages 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.
