SU-G-IeP3-15: Cloud Based Monitoring of X-Ray Angiography Equipment Performance Based On Automated Daily Sampling of Key Performance Indicators.

PURPOSE: To investigate the feasibility of deploying a novel method for the daily monitoring of x-ray Angiography (XA) equipment performance as a cloud-based service.

METHODS: From previous work, we have developed a novel image based method of testing the performance of XA equipment on a daily basis. A pre-programmed protocol on an XA system is used and images are automatically analyzed using software developed in-house, resulting in a set of Key Performance Indicators (KPI's) that can be tracked over time. The analysis software was deployed in the cloud and a routing rule was set up to automatically transfer images from the XA systems to the cloud. A web based user interface was developed with access to the KPI's for studying auto generated reports, trends and anomalies. Technologists were instructed on how to perform the daily scans with a remotely hosted instructional video and have actively participated in this endeavor for the last 7 months.

RESULTS: Quantitative performance tests have been automated including data aggregation, management, analysis and visualization which enables sampling of KPI's on a daily basis and the developed solution has been migrated to the cloud. The daily performance check routine takes ∼6 minutes per XA system in total including the transfer of images, analysis and reporting. In one instance a significant artifact and a defective pixel has been identified. A generally stable system performance has otherwise been observed as indicated by the process control charts.

CONCLUSION: A cloud based solution for monitoring the performance of XA equipment has been developed. The solution facilitates efficient data collection, enabling useful trend analysis on large data sets.
