Development Project - Ground Work The Biology Landscape • Tissue properties • Acoustic • Thermal • Irreversible changes • Ranges of variations – model and human • Anatomical • Physiologic • In vitro vs. in vivo • Transferability across species • Animal model not available for all conditions • Diet matters • Size matters 18
Development Project Project outline: Biology first and last 1. Determine the effect sought 2. Understand the tissue 3. Model the interaction 4. Design and model the beam 5. Design the transducer and system (Des. Control) 6. Test on repeatable (phantom) model 7. Measure 8. Iterate from 3 until confident with the physics 9. Test in tissue 10. Iterate from 2 until confident with the biology 11. Test in humans 12. Iterate from 2 until confident with the results 19
