Sonophoresis also known as phonophoresis, is a method that utilizes ultrasound to enhance the delivery of topical medications through the stratum corneum, to the epidermis and dermis. Sonophoresis allows for the enhancement of the permeability of the skin along with other modalities, such as iontophoresis , to deliver drugs with lesser side ...
Phonophoresis, also known as sonophoresis, is the method of using ultrasound waves to increase skin permeability in order to improve the effectiveness of transdermal drug delivery. This method intersects drug delivery and ultrasound therapy.
Phonophoresis, also known as sonophoresis, is the use of ultrasound to enhance the delivery of topically applied drugs. Home ultrasound allows the application of topically applied analgesics and anti-inflammatory agents through the therapeutic application of ultrasound.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons , muscles , joints, blood vessels, and internal organs, to measure some characteristics (e.g. distances and ...
Ultrasound is sound with frequencies greater than 20 kilohertz. This frequency is the approximate upper audible limit of human hearing in healthy young adults. The physical principles of acoustic waves apply to any frequency range, including ultrasound.
Ultrasound: Another option of drug release is through ultrasound, which is a "longitudinal pressure wave". The ultrasound can either be low-frequency, or LFUS, (between ~20 and ~100 kHz) or high-frequency, HFUS, (>1 MHz).
Schematic of Sonoporation Mechanism. This figure depicts the general understanding of sonoporation where a dedicated sonoporator applies ultrasound to induce microbubble cavitation and eventually pore formation. The therapeutic gene or drug of interest thus may translocate within the cell.
Sonophoresis: Application of an ultrasound at the skin to overcome the skin barrier. Microneedles: Application of micro-sized needles to bypass the stratum corneum for drug delivery, with the intention of decreasing pain and improving patient compliance. Magnetophoresis Application of a magnetic field to increase skin permeability.
Acoustic microscopy is microscopy that employs very high or ultra high frequency ultrasound. Acoustic microscopes operate non-destructively and penetrate most solid materials to make visible images of internal features, including defects such as cracks, delaminations and voids .
In ultrasonic testing, an ultrasound transducer connected to a diagnostic machine is passed over the object being inspected. The transducer is typically separated from the test object by a couplant such as a gel, oil or water, as in immersion testing.
