Radiography of overweight and obese patients can be challenging and frequently requires higher radiation dose due to increased body thickness and tissue density. Occasionally, results may be suboptimal or non-diagnostic due to reduced image quality. The purpose of this study was to evaluate the impact of different body habitus (soft tissue thickness) on the quality of Thoracic Skeleton and Chest/Lungs Digital Tomosynthesis (DTS) compared to radiography.
