Some ultrasound passes through the head to point B, and is reflected back to the detector. This reflection produces pulse B on the CRO. The reflection of a sound wave is called an echo.

Ultrasound can be used in industry to detect defects in metals. Materials can be tested for internal faults and cracks that could lead to the failure of a structure under certain conditions ...

SRF (Speckle Reduction Filter™) enhances image quality by reducing or eliminating the appearance of speckle echoes from ultrasound images. The degree of speckle reduction implemented is user ...

The Accuvix V20's ultrasound imaging system represents the ... enhances border detection and contrast resolution while decreasing speckle echoes. DMR+™ is particularly helpful when evaluating ...

This echo is then converted to an image that may be visualized on the ultrasound monitor. Ultrasound images are correlated with the relative intensities of their echoes on the basis of a "gray scale." ...

Medically reviewed by Rony Kampalath, MD Breast cancer ultrasound can help detect signs of potential cancer, such as ...

From January 1999 to October 2002, we prospectively studied 31 patients (mean age 57 years, range 36-82 years) with a cystic pancreatic lesion at the conventional ultrasound. Eleven patients ...

This signal triggers echoes, which are received via on-board feedback microphones. We observe that the tiny ear canal skin displacement and heartbeat vibrations modulate these ultrasound echoes.
