Senior Project PPT

  1. 1. Melissa Costa Senior Project 09-10Breast Ultrasound Phantom
  2. 2. Introduction to Ultrasound What is ultrasound imaging?  Also called scanning or sonography  Through a transducer or scanhead, the body is exposed to high- frequency sound waves  The sound waves hit features inside the body and reflect back to the scanhead  The microphone in the scanhead records the echoing waves, and the information is sent to a computer  The computer then creates a real-time picture on the monitor  By measuring these echo waves it is possible to determine how far away the object is and its size, shape, and consistency (whether the object is solid or filled with fluid)
  3. 3. Ultrasound Phantoms What are Ultrasound Phantoms and what are they used for?  A Phantom is a material that mimics tissue, for teaching people to learn to scan, or for developing scanheads so engineers dont need live tissue present. What is the difference between homemade and manufactured phantoms?  Manufactured phantoms are not very true to live tissue because manufactured phantoms are very uniform in how they look under ultrasound. (see next slide)

  6. 6. Phantom #1: Recipe Ingredients: H2O, mandarin oranges, gelatin packets, Metamucil (see picture right) Ratios (for every 250 mL of H2O):  1 tbsp Metamucil and 3 gelatin packets1. Boil 250 mL of water2. Gently whisk in 3 gelatin packets (see picture right)3. Slowly stir in 1 tbsp of Metamucil and remove any undissolved chunks
  7. 7. Phantom #1: Recipe cont’d4. Pour 250 mL into container and refrigerate for 1-2 hrs5. Add mandarin oranges and make sure fruit isn’t touching (see picture right)6. Refrigerate for 1 hour7. Repeat steps 1-4 for top layer (see picture right)

  10. 10. Phantom #2: Recipe The recipe is the exact same but instead of 2 layers, there are 3 The measurements for the ingredients in each layer are:  166.6 mL of H2O  2 gelatin packets  2 tsp of Metamucil (3 tsp=1tbsp)

  14. 14. Phantom #3: Recipe My idea for this phantom was to chill 6 layers at different angles, in an attempt to create more amorphous layers The measurements for the ingredients in each layer are:  83.3 mL of H2O  1 gelatin packet  <1 tsp of Metamucil (about 5/6 tsp)

  19. 19. Phantom #4: Recipe1. Pack a container with a can of mandarin oranges, so they just barely touch and stack nicely2. Slowly pour the gelatin/Metamucil solution over the oranges, trying not to disrupt their form, and leaving about half an inch of gelatin/Metamucil solution at the top The measurements for the ingredients in each layer are:  416.6 mL of H2O  5 gelatin packets  5 tsp of Metamucil

  25. 25. Conclusion What I learned/Usefulness: Use less Metamucil than recipe– my project helped the ultrasound engineers know how much Metamucil to use for different body parts, and specifically how much Metamucil to use for breast tissue What I would do next: If I had access to a walk in refrigerator, I would try recipe #4, but rotate the container as the gelatin was congealing
