Texray HeadPeace and MindPeace were evaluated for reducing radiation exposure to the head and neck during clinical interventions. A standard thyroid collar and a ceiling-mounted lead glass shield were used as comparisons.
Preliminary TLD data showed that MindPeace (extended thyroid collar) reduce radiation in the throat, chin, and ear slices (A, B, C). Some shielding effect using MindPeace was also seen in the brain and skull slices (D, E). For the standard thyroid collar a reduction was only seen in the throat slice (A) and partly in the chin slice (B). HeadPeace showed a shielding effect in the skull slice (E) up to 2 cm depth where HeadPeace covered the phantom head.
For optimal radiation protection, devices that protect the entire operators head against scattered radiation should be used. However, in clinical practice, this may not always be possible. Moreover, particularly during complex cases when radiation protection may be most relevant, optimal placement of lead glasses may not always be achievable. HeadPeace and MindPeace may therefore provide complimentary protection
