The propagation of ultrasonic waves is nonlinear. Phenomena associated with the
propagation of diagnostic ultrasound pulses cannot be predicted using linear assumptions …

Processes that can produce a biological effect with some degree of heating (ie, about 1° C
above the physiologic temperature) act via a thermal mechanism. Investigations with …

Fast and accurate tissue elasticity imaging is essential in studying dynamic tissue
mechanical properties. Various ultrasound shear elasticity imaging techniques have been …

Acoustic characterization of high intensity focused ultrasound (HIFU) fields is important both
for the accurate prediction of ultrasound induced bioeffects in tissues and for the …

Background The stimulation of nerve or cortical tissue by magnetic induction is a relatively
new tool for the non-invasive study of the brain and nervous system. Transcranial magnetic …

The thermal index (TI) has been used as a relative indicator of thermal risk during diagnostic
ultrasound examinations for many years. It is useful in providing feedback to the clinician or …

Reliable acoustic characterization is fundamental for patient safety and clinical efficacy
during high-intensity therapeutic ultrasound (HITU) treatment. Technical challenges, such as …

This article reports spatiotemporal deconvolution methods and simple empirical formulas to
correct pressure and beamwidth measurements for spatial averaging across a hydrophone …

Biomedical applications of ultrasound have experienced tremendous growth over the past
50 years. Early work in thermal therapy and surgery soon was followed by diagnostic …

The spatiotemporal transfer function for a needle or reflectance-based fiber-optic
hydrophone is modeled as separable into the product of two filters corresponding to …
