Room: Track 4
In the past two decades diagnostic physics and radiology have invested an enormous amount of effort to optimize patient doses from imaging studies. Currently, doses from many scans are so low that many in the community are beginning to question the utility of further reduction. Although the risk of low-doses of radiation is controversial, there is general acceptance in the imaging community that doses greater than 100 mSv do increase risk of stochastic effects (albeit weakly). Unfortunately, there is little information available in the current literature and little discussion within imaging professional circles regarding patients who receive 100mSv+ from imaging studies.
1. Learn about the prevalence and demographics of patients estimated to receive 100mSv+ of effective dose from imaging studies.
2. Understand the factors leading to the large doses.
3. Review techniques and technology used to keep doses low without sacrificing image quality.
