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...
travel at different speeds through materials of different densities. ... An ultrasound
system can produce images of body structures because sound waves?
In this edition of How Stuff Works, we will look at how ultrasound works, what type
of ... The sound waves travel into your body and hit a boundary between tissues (
e.g. ... The reflected waves are picked up by the probe and relayed to the
machine. ... Ultrasound image of a growing fetus (approximately 12 weeks old)
inside a ...
Ultrasound imaging uses sound waves to produce pictures of the inside of the
body. ... Because ultrasound images are captured in real-time, they can show the
structure and movement of the body's internal organs, as well as blood flowing ...
While the term ultrasound generally refers to sound waves with frequencies
above ... albeit lower resolution and can be used to image deeper structures. ...
as it passes through tissue because parts of it are reflected, scattered, absorbed,
... Typically in soft tissues, the amplitude of an echo produced at a boundary is
only a .....
This is because sound waves are actually vibrations passing through a material.
... Some of the pulses will be reflected by internal body structures and send ...
Echoes, which show up as bright or white spots in the image are produced by ...
The basic functional components of an ultrasound imaging system are shown
The term "ultrasound" actually applies to sound waves spanning a range of ...
because speed of sound is basically consistent within a particular medium under
... Baleen whales like the blue whale can produce sound with a frequency of 10
Hz, ... of different densities in the body; denser structures will cause a stronger
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
An ultrasound scan uses high-frequency sound waves to make an image of a ...
The ultrasound machine directs high-frequency sound waves at the internal body
structures ... Sometimes, doctors will use ultrasound scanning to monitor and
guide ... easily by ultrasound because air prevents the transfer of the sound
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,
