OBJECTIVE. The purpose of this study was to provide enough information so beginners can feel comfortable starting and completing a simple radiology process improvement project. CONCLUSION.

Addressing these issues improves patient care and operational efficiency. We provide a review of our approach to process improvement and the established improvement methods. Many organizations and companies are available to support medical practices as they enter this field.
