Blueprint: Low-Dose Chest Radiography Protocol for Tuberculosis Screening — Implementation Specification

Implementation specification for a low-dose PA chest radiography protocol for tuberculosis screening at 0.0069 mGy entrance surface dose per film, 43.48 times below standard practice, preserving cavities, infiltrates and nodules of 5 mm or larger while explicitly excluding miliary disease. It specifies equipment, exposure, patient procedure, image reading rules, quality control, operating envelope, tolerances, failure modes and safety limits. DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT, NOT CLINICALLY TESTED. Blueprint for the protocol published as DOI 10.5281/zenodo.24108473.
