Medical ultrasound is a diagnostic imaging technique based on the application of
ultrasound. It is used to see internal body structures such as tendons, muscles,
joints, ... Ultrasound is sound wave...

Dec 16, 2014 ... Because ultrasound images are captured in real-time, they can show ...
Ultrasound imaging (sonography) uses high-frequency sound waves to view
inside the body. ... based on the reflection of the waves off of the body structures.
... as X-rays or other types of imaging systems that use ionizing radiation.
The ultrasound image is created by first transmitting sound waves into the body
and ... This is achieved using a hand held probe which contacts the body via a
water based gel. ... in ultrasound imaging has a profound effect on how structures
appear. ... Shorter pulses can be achieved using higher frequency, so the highest
ultrasound or sonography, in medicine, technique that uses sound waves to
study ... sound waves at tissues in the body to generate images of anatomical
structures. ... A technique called Doppler imaging ultrasonography can also be
used to view .... Because air acts as such a strong reflector of an ultrasonic wave,
gel or ...
The human ear can hear sound waves that have a frequency of 20-20,000 ...

Because of this interface, some of the sound wave will be reflected back and ...
Ultrasound medical imaging produces readable images of inner body structures
In this edition of How Stuff Works, we will look at how ultrasound works, what type
of ... a medical imaging technique that uses high frequency sound waves and
their echoes. ... The sound waves travel into your body and hit a boundary
between tissues (e.g. ... The transducer probe is the main part of the ultrasound
While the term ultrasound generally refers to sound waves with frequencies
above 20,000 ... albeit lower resolution and can be used to image deeper
structures. ... because parts of it are reflected, scattered, absorbed, refracted or
diffracted. ... Typically in soft tissues, the amplitude of an echo produced at a
boundary is only a ...
Ultrasound has been used to image the human body for over half a century. ....
Sound waves can be described in terms of their frequency (measured .... of a
