Frequency and failure of high-resolution monitors in a filmless imaging department

摘要

Abstract: The purpose of this study was to assess the rate of failure of the high resolution monitors used for primary diagnosis in a filmless radiology department and to analyze the type of problems encountered as well as the action taken to report the monitors. Data were collected from PACS service logs to determine rates of monitor adjustment and replacement, the symptoms reported, and the action taken. Analysis of monitor service records demonstrated a high rate of monitor replacement resulting in a relatively short 'life expectancy of 2.4 years. The result of this study support our subjective impression and those of other colleagues in the PACS community of an unacceptably high monitor failure rate with 2,000 pixel monitors used for primary diagnosis. Requests for proposals for PACS and service contracts must carefully specify requirements for monitor images quality and conditions under which the vendor is required to replace these monitors. !9
