Focused ultrasound may be used to generate highly localized heating to treat cysts and tumors (benign or malignant). This is known as Magnetic Resonance guided Focused Ultrasound (MRgFUS) or High Intensity Focused Ultrasound (HIFU).
Focused-ultrasound-mediated diagnostics or FUS-mediated diagnostics are an area of clinical diagnostic tools that use ultrasound to detect diseases and cancers. Although ultrasound has been used for imaging in various settings, focused-ultrasound refers to the detection of specific cells and biomarkers under flow combining ultrasound with lasers, microbubbles, and imaging techniques.
Focused assessment with sonography in trauma (commonly abbreviated as FAST) is a rapid bedside ultrasound examination performed by surgeons, emergency physicians, and paramedics as a screening test for blood around the heart (pericardial effusion) or abdominal organs (hemoperitoneum) after trauma.
The treatment is an incisionless surgery, by which several ultrasound beams are focused down to millimeter accuracy, carefully creating a small lesion in a specific part of the brain. The patient lies in an MRI scanner that allows frequent scans to monitor the location, size and temperature of the lesion being created.
The bottom probe demonstrates the use of ultrasound for therapeutic benefits, which often utilize high-energy, focused ultrasound beams. In the above applications, the ultrasound passes through human tissue where it is the main source of the observed biological effect (the oscillation of abrasive dental tools at ultrasonic frequencies therefore ...
Ultrasound imaging deposits energy over a large area while therapeutic ultrasound focuses the energy on one target site. Focused ultrasound for intracrainial drug delivery is a non-invasive technique that uses high-frequency sound waves (focused ultrasound, or FUS) to disrupt tight junctions in the blood–brain barrier (BBB), allowing for increased passage of therapeutics into the brain.
"Advances in focused ultrasound technology offer the potential for non-invasive, targeted, and temporary opening of the blood-brain barrier.
The focused ultrasound waves generate high temperatures within smaller areas. The temperature when maintained for sufficient a period of time results in the ablation of the fibroids. The therapy procedure is guided by Magnetic Resonance Imaging (MRI) with real time feedback, which helps in the focused ablation of the target location. [3]
