Quality control of storage phosphor digital radiography systems

Area of Science:

• Medical Imaging
• Radiography
• Quality Control

Background:

• Storage phosphor (SP) devices are crucial for digital radiography, but their quality control (QC) is complex.
• Self-correcting image-processing software in SP systems complicates traditional QC methods.
• Ensuring diagnostic image quality in Picture Archiving and Communication Systems (PACS) requires robust QC.

Purpose of the Study:

• To address the complexities of QC for storage phosphor digital radiography systems.
• To propose practical QC tests and initial control limit approximations.
• To enhance the reliability of image information for diagnostic purposes.

Main Methods:

• Inspection of hard copy images for reject analysis.
• Examination of imaging plates and cassettes.
• Development of starting approximations for QC test control limits.

Main Results:

• Established practical methods for QC, including image inspection and hardware checks.
• Provided initial approximations for setting control limits in QC tests.
• Highlighted the importance of QC for diagnostic accuracy in digital radiography.

Conclusions:

• Implementing recommended QC tests and approximations can improve storage phosphor system performance.
• Adequate QC is essential for maintaining diagnostic quality in images managed by PACS.
• Further research is needed to refine control limits for SP digital radiography QC.
