Open Source NIST Phantom

Repository to host the open-source NIST phantom.

CAD Files for 3D Printing

STL files that can be used for 3d printing are located in the stl-files directory.

Files that can be used for modifying the CAD design of the phantom are located in the stp-files directory.

Components

Additional components for the phantom can be found at:

Tools

  • 3.5mm Allen wrench for bolts
  • Adjustable wrench for fill plugs
  • Bolts:
    • Metric tap: M4 x 0.7
    • (Optional) 3.3mm drill bit
  • NPT fill plug:
    • NPT tap (if using NPT fill plug): size: 1/8; threads per inch: 27
    • (Optional) Q drill bit
  • Metric fill plug:
    • Metric tap: M10 x 1.5
    • (Optional) 8.5mm drill bit

Assembly

  1. If printing with water permeable material, you may want to coat the inside of the phantom with a waterproof layer. Plasti Dip can work well for this.
  2. The bolt holes and fill port may need to be expanded if the 3D print resulted in a narrower hole. If so, drill out the holes using the tools described above.
  3. Tap the bolt holes and fill port.
