Summary

A novel paper phantom for Single Photon Emission Computed Tomography (SPECT) evaluation was developed using an ink-jet printer. This method allows for accurate activity control and easy phantom creation, provided the paper source pitch is under 10 mm.

Area of Science:

  • Medical Imaging
  • Nuclear Medicine
  • Radiopharmacy

Context:

  • Accurate phantoms are crucial for SPECT system calibration and performance evaluation.
  • Existing phantom fabrication methods can be complex and time-consuming.
  • Developing cost-effective and easily reproducible phantoms is an ongoing need in nuclear medicine.

Purpose:

  • To develop a simple and accurate paper phantom for SPECT evaluation.
  • To investigate the feasibility of using ink-jet printing for creating SPECT phantoms.
  • To establish parameters for optimal paper phantom performance.

Summary:

  • A paper phantom was created using an ink-jet printer with technetium-99m (99mTc) labeled ink.
  • The phantom's accuracy, activity control, and reproducibility were evaluated.
  • Optimal performance, with %RMSU <= 5%, was achieved when the paper surface source pitch did not exceed 10 mm.

Impact:

  • This study presents a simple and controllable method for phantom fabrication in SPECT experiments.
  • The developed paper phantom offers a cost-effective alternative for SPECT quality assurance.
  • The findings facilitate easier control of activity density in phantom-based research.
