  10. Abstract Our objective is to build an apparatus to house between one and three zebrafish during a diagnostic micro CT scanning process. The device will be used for an evaluation of carcinogenesis in a zebrafish model research project currently being conducted at the UW hospital. The ultimate goal of this research is to cure cancer using drugs which eliminate the blood supply to malignant tumors. To guarantee the best imaging quality, the device must be composed of materials compatible with the micro CT scanner and must immobilize the fish. The zebrafish must remain alive for the duration of the twenty minute imaging process.

  11. Project Motivation • Client’s Objective • An Evaluation of Carcinogenesis in Zebrafish Model • Ultimate Goal: Cure Cancer by Eliminating Malignant Tumors • Client’s Device • Cardboard • Zebrafish Slits • High Mortality Rate Client’s Current Device

  12. Background Information • CT = Computed Tomography • Benefits of Zebrafish Research • Quick Breeders • Low Maintenance • Mapped Genome • Zebrafish Anatomy • Length: 1-6cm • Lifespan: 2 years • Water Temp: 64-75° F • Bony Fish: Breathe Without Moving Typical CT Scanner

  13. Design Specifications • Max Dimensions: • Width- 4 in • Length- 1 ft • Height- <4 in • No Leakage • Zebrafish Must Survive • Metal, Glass, and Dense Materials Must Not Be Used • Minimize All Motion of the Zebrafish • Disposable or Autoclavable Micro CT Scanner

  14. Testing: Phase 1 Thirty Minute Bob Date: February 11, 2004 Purpose: Determine Zebrafish Survival Rate in Cuvette Procedure: Leave Fish in 3.5 ml Cuvette for 30 min Conclusions: Fish Can Survive in 3.5 ml Cuvette for 30 min No Adverse Behavior in Cuvette Fish Preferred Horizontal Orientation

  15. Testing: Phase 2 • Dates: April 4, April 6, April 12, 2004 • Purpose: Test Restraints in Cuvette • Procedure: • Test Various Restraints in Cuvettes for 20 min 1. 1.5 ml semi-micro cuvette with dense dish scrubber 2. 1.5 ml semi-micro cuvette with low-density tile sponge 3. 3.5 ml cuvette with low-density tile sponge • Conclusions: • 75% Survival Rate with Restraint 1 • 100% Survival Rate with Restraint 2 and 3 • Restraint 2 and 3 Equally Immobilized the Fish

  16. Final Design: Prototype I • Calculated Base • Cuvette Apparatus • Allows 1-7 Zebrafish Standard Cuvette & Sponge Vs. Semi-Micro Cuvette & Sponge

  17. Prototype I: Micro CT Testing Semi-micro Cuvette Flanked by Two Standard Cuvettes

  18. Final Design: Prototype II • Calculated Base • Micro CT Compatible • Allows 1-3 Zebrafish • Standard Cuvette Design for Maximum Immobility Standard Cuvette & Sponge

  19. Prototype II: Micro CT Testing Three Dimensional View of Three Standard Cuvettes

  20. Manufacturing • Cut the Plexiglas • Table Saw • Band Saw • Milling Machine • Gluing • Finish Sanding • Testing

  21. Materials and Costs

  22. System Advantages • High Survival Rate • Immobilizes Zebrafish • Compatible with Micro CT Scanner • Disposable Design • Easy Maintenance • No Cross-Contamination • Flexible 1-3 Zebrafish Design

  23. Future Work • Individually Scan Sponge • Keep Fish Alive for Extended Periods of Time • Determine How to Further Reduce Motion • Find Better Method of Inserting Fish and Sponge into Cuvette
