A multipurpose anthropomorphic neck phantom was designed and fabricated for use in medical
applications. The designed neck phantom is composed of seven elliptic cylindrical slices with semi-major
axis of 14cm and semi-minor axis of 12.5 cm, each having the thickness of 2cm.Thyroid gland, bony part
of the neck, and the wind pipe were also built inside the neck phantom. For the purpose of medical
dosimetry, some holes were drilled inside the phantom to accommodate the TLDs with different shapes 30
and dimensions. For testing the qualities of images in nuclear medicine, the thyroid gland was built
separately to accommodate the radioactive iodine. Lastly, the application of the phantom in external
dosimetry was tested by exposing the phantom to 662 keV photons from Cs-137, using TLD-100 chips.
Finally, the nuclear medicine images were obtained by inserting 131I in both male and female thyroid
parts.
