Researchers from the University of Buffalo and the University Health Network of Toronto recently developed a contrast agent called Porshe Microbubbles which offers better visibility in (PAT). A relatively new imaging technology, PAT is the combination of photoacoustic (PA) and ultrasound imaging, bringing together their advantages; high contrast visibility and deep penetration. Photoacoustic was introduced [...]
High Intensity Focused Ultrasound (HIFU) is a newly designed non-invasive cancer treatment that has the ability to accurately destroy tumors , basically the HIFU operates by bringing numerous beams of ultrasound to a point within the tumor, this effectively destroys the tumor and the surrounding tissue remains unharmed. This sound wave will pass through the [...]
A type of technology that has shown real worth in the clinical setting is shortwave diathermy, as it can aid greatly in controlling pain and increasing the blood flow to damaged muscle areas. Shortwave diathermy acts with deep heat, as opposed to sound waves. In conjunction with other non medication-based therapies, shortwave diathermy can help a large number of patients with varying degrees of injury, as well as different types of injury.
Ultrasound elastography is the use of ultrasound to produce measurements or images of tissue stiffness. Several different approaches are used, but all rely on creating some form of displacement of the tissue and measuring the response. Ultrasound elastography can be implemented in a number of ways; from simple add-ons for conventional ultrasound scanners, to dedicated [...]
Diagnostic ultrasound is an imaging modality that is useful in a wide range of clinical applications, particularly prenatal diagnosis. There is, to date, no evidence that diagnostic ultrasound has produced any harm to humans (including the developing fetus). Diagnostic ultrasound is generally perceived by users and patients as a safe technique with no adverse effects. [...]
Obstetric ultrasound is the use of ultrasound scanning in pregnancy. Since its introduction in the 1950′s, ultrasonography has become a very useful diagnostic tool in obstetrics. Traditional obstetric sonograms are done by placing a transducer on the abdomen of the pregnant woman. One variant is a transvaginal sonography which is performed with a probe placed [...]
