2. OVERVIEW
 Why the USG
 Mechanics and principles of USG
 FAST
 E FAST

3. Why the USG
 Stethoscope of Emergency
Physician
 Clinical assessment of critically
ill patients
 No radiation , better portability
 Real time imaging ,faster
 Low cost

4. USG

5. Probe
 Transducer converts one type of energy in
to sound wave
 Transducer contains piezoelectric
elements /crystals which produce the
ultrasound pulses
 These elements converts electrical energy
into a mechnical ultrasound wave
