RT Journal Article SR Electronic T1 A Method for Sizing the Pinhole Thyroid Image JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 207 OP 208 VO 10 IS 4 A1 Blue, Peter W. A1 Carr, James R. YR 1982 UL http://tech.snmjournals.org/content/10/4/207.abstract AB We report use of a frog-shaped thumbsplint, to which Co-57 sources have been attached, to aid in imaging thyroid glands. Properly placed in a camera’s field of view, the device projects a scale from which a full-sized, one-to-one image is produced and from which direct measurements can be made.
