Technische Innovationen zur Optimierung der Ultraschallbildgebung

Zusammenfassung

Aufgrund der hohen Inzidenz von Schilddrüsenerkrankungen besitzt die Ultraschalluntersuchung des Halses in vielen nuklearmedizinischen Abteilungen einen hohen Stellenwert. Ein präzises Sonogramm mit hoher Ortsauflösung und Bildschärfe über den gesamten Abbildungsbereich bei gleichzeitig minimaler Artefaktbelastung, ist die Voraussetzung, um dem Anspruch hoher diagnostischer Genauigkeit in der modernen Medizin gerecht zu werden. In den letzten 20–30 Jahren konnte eine Vielzahl wegweisender technischer Innovationen, wie die Entwicklung des Matrix-Arrays, die elektronische Bildfokussierung, die multidirektionale Abstrahlung, die Artefaktlimitation durch Speckle-Reduktion und Harmonic Imaging sowie die Möglichkeit der Sichtfelderweiterung, umgesetzt werden.

Abstract

Due to the high incidence of thyroid disease, ultrasound examination of the neck has high priority in many nuclear medicine departments. A precise sonogram with high spatial resolution and image sharpness over the entire imaging area, combined with minimal artifacts, is the prerequisite for meeting the demand for high diagnostic accuracy in modern medicine. In the last 20–30 years, a number of significant technical innovations have been implemented, such as the development of the matrix array, electronic image focusing, realtime compound imaging, artifact limitation by speckle reduction and harmonic imaging, as well as the possibility to extend the field of view.
