Title
Estimated Radiation Dose to Participants Receiving Chest X-Rays in the National Lung Screening Trial (NLST)
Summary
Data from part A of the “Chest X-ray Screening Examination Form (XRY)” describing the radiographic technique used for each chest xray examination in the trial will be used to deduce the effective radiation dose of each examination. The radiographic techniques along the radiation beam quality obtained as a part of annual QA tests will be analyzed using a Monte Carlo radiation transport analysis to compute effective dose. The individual results will be provided to WESTAT for incorporation in the trial database. Summary statistics from the results will be reported.
Aims

1. Deduce the effective radiation dose associated with individual NLST chest x-ray examinations.
2. Describe the distribution of NLST effective dose chest x-ray values.
