Abstract:
Objective To study the quality assurance(QA) and quality control(QC) of PACS image display device in the department of radiology equipped with PACS and radiology information system (RIS). Methods Routine maintenance and periodic calibration were performed using photometer and automatic calibration software according to American Association of Physicists in Medicine Task Group 18 (AAPM TG18) test patterns and evaluating criterion. Digital image and communication in medicine (DICOM) gray scale standard display function (GSDF) standard calibration ,maximum luminance and minimum luminance,luminance uniformity,display resolution and geometry distortion adjustment were performed quarterly on BARCO CRT displays. Results All the results were well conformed to the criteria recommended by the AAPM TG18. About 95 percents of radiological images were interpreted on the PACS diagnostic image display.Conclusion The QC program of PACS image display device is an essential to ensure high-quality in digital medical environment.
