WebThomas L. Szabo, in Diagnostic Ultrasound Imaging, 2004 12.5.1 Introduction. Tissue harmonic imaging (THI), also known as “native harmonic imaging,” has been praised as being a breakthrough in ultrasound imaging that is as important as Doppler or color flow imaging. Equally unexpected was its accidental discovery on imaging systems and … WebUltrasound waves are produced by a transducer, which can both emit ultrasound waves, as well as detect the ultrasound echoes reflected back. In most cases, the active elements in ultrasound transducers are made of special ceramic crystal materials called piezoelectrics.

WebUltrasound imaging is also called sonography. It uses a small probe called a transducer and gel placed directly on the skin. High-frequency sound waves travel from the probe through the gel into the body. The probe collects the sounds that bounce back. A computer uses those sound waves to create an image. Ultrasound exams do not use radiation .
WebTraditional ultrasound images are formed by first transmitting ultrasound to a medium of interest and then receiving the ultrasound signals resulting from the interaction of the transmitted signals with the medium. Web7 sep. 2024 · How does ultrasound work?¹. 1. High-frequency sound waves are transmitted from a transducer. 2. These sound waves are then reflected by different tissue types in different ways. 3. The reflected sound waves are then picked up by the ultrasound transducer. 4. The sound waves are then transformed into an image by special software.
