Ultrasound Technology
By Peter Cerce
Introduction
 Ultrasound Technology has been around for many
years.
 The first one was used in 1942 by Karl Dussik.
 It is designed to be used on tissues and organs.
 It is not good on bones.
 It can be used for more than
Just pregnancy.

How They Work
 An ultrasound machine sends sound waves into the
body using a transducer.
 The waves then reflect off the organs back towards the
transducer.
 From there they are turned into electrical waves and
sent into a sonogram.
 The signals are turned into
Pictures.

Tendon Fenestration
 It is an injection into an inflamed or irritated tendon.
 Ultrasound is used to guide the needle through the are
to distribute the medicine.
 One person operates the ultrasound and the works the
needle into the location.
 Makes it very easy to be precise.
 This minimizes pain and problems.

Drug Delivery
 Using ultrasounds in drug delivery is a very new topic.
 It is being tested right now on rabbits.
 The drug would be delivered through the cornea.
 An eye cup is placed over the eye and the solution is
placed in in the cup

Drug Delivery Cont.
 In this case the transducer is set to 400 Hz and 600Hz.
 This makes dealing with illnesses with the eyes easier
to treat.
 This study proved that it can work but needs much
more testing.
 As of right now there are serious risk of doing this
procedure.
Discussion
 Ultrasounds have come a very long way over the years.
 They can be used in a number of medical procedures.
 It can be used for pregnancies, injections, and now
even drug delivery.
 There has been great use for this technology and new
discoveries are being made.
