What is Engineering?

• The major goal of engineers is to improve our
  quality of life.
• Take known technologies and improve them
• OR
• Create new technologies

Example Ultrasound

• Imaging technique that detects an object based on
  how well it echoes sound waves
• Used to detect heart defects, age of fetus,
  position in uterus, twins
• Can determine sex of baby by week 18 or 20 of
  pregnancy
• Also used to thermally apply medications to
  injuries

Strengths/Weaknesses

• Strengths
• Easily detects soft tissue and muscle
• Renders live images
• Detects structures of organs

• Weaknesses
• Cannot penetrate bone
• Doctor dependent interpretation
• Possible dangers
• Heat generation
• Bubble formation
