Abstract Despite the ubiquitous use over the past 150 years, the functions of the current medical needle are facilitated only by mechanical shear and cutting by the needle tip, i.e. the lancet. In this study, we demonstrate how nonlinear ultrasonics

Localized delivery of drugs into articular cartilage (AC) may facilitate the development of novel therapies to treat osteoarthritis (OA). We investigated the potential of spark-gap-generated sound to deliver a drug surrogate, i.e., methylene blue (MB

Fine-needle aspiration biopsy (FNAB) is a well-known procedure employed in the diagnostics of various tissue pathologies. Despite the common use of fine-needles in biopsy, substantial limitations related to the yield insufficiency of the biopsy sampl

Ultrasonic bursts from two transducers were stroboscopically imaged with a Schlieren setup. A standard optical lens was used to calibrate the Schlieren images. The inverse Abel transform was used to gain the radial pressure distribution at each point

Non-linear acoustic waves were used to excite propagating waves on a curved biological membrane. A non-contact method was used to measure the displacement of the membrane at the pickup point. The frequency content, time-of-flight, and amplitude of th

Localized delivery of drugs into an osteoarthritic cartilaginous lesion does not yet exist, which limits pharmaceutical management of osteoarthritis (OA). High-intensity focused ultrasound (HIFU) provides a means to actuate matter from a distance in

Current lane departure warning systems are video-based and lose data when road- and weather conditions are bad. This study sought to develop a lane departure warning algorithm based on the signal drawn from the steering wheel. The rationale is that a
