Effect of thyroid shielding during mammography : measurements on phantom and patient as well as estimation with Monte Carlo simulation [PDF]

, 2018
Background: During mammography, the thyroid is exposed to scattered radiation from breast tissue and device. This may increase the risk of radiation induced thyroid cancer. Methods: We investigated the scatter radiation exposition of the thyroid and the

Deriving target exposure indices for common radiography exams based on automatic exposures of flat‐field phantoms

Journal of Applied Clinical Medical Physics, Volume 27, Issue 5, May 2026.
Abstract Background The IEC exposure index (EI), deviation index (DI), and target exposure index (EIT), represent critical standardized metrics for the evaluation of exposure and quality in radiographic imaging. Purpose This work develops and validates a systematic procedure to estimate the EIT for eight of the most common radiography imaging protocols
