Abstract:Objective To study the DR (Digital Radiography) image re-photography factors resulting from
bad image quality and related improvement measures. Methods Altogether 98503 cases in PACS (Picture
Archiving and Communication System) were analyzed retrospectively to analyze the factors of the DR
image re-photography and put forward related improvement measures. Pre- and post-improvement DR
image re-photography ratios were compared. Results The DR image re-photography ratio was 4.89%
and factors that caused re-photography included wrong position (2697 cases, 56.05%), foreign materials
(990 cases, 20.57%), patients’ mobility (577 cases, 11.99%), machine fault (355 cases, 7.37%) and the
inappropriate X-ray dosage (193 cases, 4.02%). Having taken improvement measures, the ratio of the DR
image re-photography reduced from 4.38% to 3.81% in 6 months. Conclusion Regular analysis of the
DR image re-photography factors and formulation of related improvement measures could improve the
image quality, which were also effective measures for quality control and quality assurance.
