Background: Recently, ultrasonic neuromodulation research has been an important and interesting issue. Ultrasonic neuromodulation is possible by the use of low-intensity transcranial focused ultrasound (tFUS) to stimulate or inhibit the neural structures. The primary capability of this method is the improvement in the treatment progress of certain neurological and psychiatric disorders noninvas...

Ultrasound guided epidural anaesthesia, regional blocks, internal jugular vein cannulations, ultrasound lithotripsy and ultrasound assisted thrombolytsis are some of the current medical applications of ultrasound technology [1,2]. Low-intensity ultrasound produces physiological effects such as stimulation of bone-growth, and has the potential to temporarily disrupt the blood-brain barrier for d...

Ultrasound images are characterized by their special speckle appearance, low contrast, and low signalto-noise ratio. It is always challenging to extract important clinical information from these images. An important step before formal analysis is to transform the image to significant features of interest. Intensity based methods do not perform particularly well on ultrasound images. However, it...

Ultrasonic hearing is widespread among moths, but very few moth species have been reported to produce ultrasounds for sexual communication. In those that do, the signals are intense and thus well matched for long distance communication. By contrast, males of the Asian corn borer moth (Crambidae) were recently shown to whisper extremely low-intensity ultrasonic courtship songs close to females. ...
