A Method for Sizing the Pinhole Thyroid Image

[摘要] 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.
