Combined drug delivery and treatment monitoring using a single high frequency ultrasound system

International Journal of Hyperthermia
Ultrasound-mediated drug delivery is typically performed using transducers with center frequencies [Formula: see text]1 MHz to promote acoustic cavitation. Such frequencies are not commonly used for diagnostic ultrasound due to limited spatial resolution.

Transducer for harmonic intravascular ultrasound imaging [PDF]

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2005
A recent study has shown the feasibility of tissue harmonic imaging (THI) using an intravascular ultrasound (IVUS) transducer. This correspondence describes the design, fabrication, and characterization of a THI-optimized piezoelectric transducer with oval aperture of 0.75 mm by 1 mm. The transducer operated at 20 MHz and 40 MHz, and was comprised of a

Predicting mammographic density with a linear ultrasound transducer

Senologie - Zeitschrift für Mammadiagnostik und -therapie, 2022
Abstract Background High mammographic density (MD) is a risk factor for the development of breast cancer (BC). Changes in MD are influenced by multiple factors such as age, BMI, number of full-term pregnancies and lactating periods.
