  abstract     = {{In spite of the outstanding importance of neuronavigational techniques the neurosurgeon has still highly to rely on his visual as well as tactile sense and his experience in distinguishing tumor tissue from intact brain parenchyma. All the more - as neuronavigation is based on preoperative imaging scans - considerable brain shift may occur during surgery and that will lead to erroneous results. Furthermore the surgeon loses his tactile sense during endoscopic surgery. Therefore control of tissue manipulation is limited today to the fiberoptic image techniques, possibly ensured by neuronavigational supervision or haptic feedback systems. In robotic guided surgery the missing tactile sensing will be particularly crucial. The human sense of touch is a highly complex sensory perception comprising epicritical and propiozeptive information processing. The development of a tool for intraoperative tactile perception will be a highly challenging task to improve the safety during surgery. Different sensor concepts (elasticity probe and resonant piezoelectric sensor) have been set up and adapted to distinguish elasticity differences in soft tissue mimicking gel phantoms. The elasticity probe is based on two leaf springs of different bending stiffness. The two tips of the beams act both on the material to be tested. The two deflections measured by strain gauges are processed in a mathematical model calculating the phantoms' stiffness. In contrast to this differential sensing concept the piezoelectric sensor, which is driven at its resonance, measures stiffness and damping of the phantoms by evaluating frequency or phase shift and amplitude change. Gelatine gels of different concentrations (5{\%}, 10{\%}, 20{\%} of gelatine) have been used for a characterization of sensor elements and their sensitivity to elasticity distinctions. Using the hand-guided elasticity probe the determination of gel elasticity is performed with high reliability. By constant mechanical load the piezoelectric sensor also presents a proportional dependency of tissue elasticity.}},

  abstract     = {{Die kontinuierliche und zuverlässige Konzentrationsmessung in Flüssigkeiten
ob zur Dosierung oder Prozessverfolgung stellt auch heute noch eine große
messtechnische Herausforderung dar. Akustische Sensorsysteme sind für diese
Messaufgabe insbesondere unter industriellen Einsatzbedingungen prädestiniert.
Es gibt eine Vielzahl verschiedener sorgfältig entworfener Ultraschallsensoren,
die diese Aufgabe durch Bestimmung der Schallgeschwindigkeit und
der akustischen Impedanz lösen. Sie basieren meist auf senkrechten Durchgängen
des Schalls durch Grenzschichten, was sie sehr empfindlich gegenüber Ablagerungen
macht.
Dieser Beitrag liefert einen neuen Ansatz, indem die gesamte Oberfläche des
Messraumes als akustischer Wellenleiter gestaltet und genutzt wird. Es hat sich
gezeigt, dass sich durch Ausnutzen verschiedener Simulationswerkzeuge die
Hauptkomponenten eines Empfangssignals berechnen lassen, die eindeutig den
verschiedenen modalen Anteilen zugeordnet werden können. Damit ist es möglich,
allein aus dem Empfangssignal eines herkömmlichen Ultraschallwandlers
auf die modalen Anteilsfaktoren zu schließen. Mit Hilfe dieser Koeffizienten
und eines Modells des akustischen Wellenleiters lässt sich ein Gleichungssystem
aufstellen, das den Zusammenhang zwischen Dissipation in der Flüssigkeit
sowie der durch Wellenleitergeometrie und Impedanzverhältnisse bedingten
Signaldämpfung und den Amplituden der modalen Anteilsfaktoren beschreibt.}},

  abstract     = {{In many different ultrasound applications mirrors are often used to deflect ultrasonic waves. The dimensions of the mirror and the applied materials have an essential influence on the output signal characteristics and the obtained measuring quantities. The extension of mirror geometry is not necessarily associated with a higher reflection coefficient. This can be explained with the aid of coincidence condition. A second criterion aims at the avoidance of the mirror resonance. This two conditions lead to an optimal dimensioning of mirror geometry with given material properties and operation mode, as exemplified for a rectangular mirror.}},
