Chen, C. (author), Pertijs, M.A.P. (author)As medical ultrasound imaging moves from conventional cart-based scanners to new form factors such as imaging catheters, hand-held point-of-care scanners and ultrasound patches, there is an increasing need for integrated transceivers that can be closely integrated with the transducer to provide channel-count reduction, improved signal quality...journal article 2021

Tams, Jelle (author)This work presents a type of low noise amplifiers (LNA) that are used for ultrasound imaging systems. To account for the attenuating nature of ultrasound echo signals, a so-called time gain compensation (TGC) circuit is required. By increasing the gain over time, the output dynamic range is decreased, while the switching artifacts are suppressed...master thesis 2020
