Abstract

A patient image data processing system comprises a first validation processor for parsing a message conveying patient medical image data from an image provider to identify image metadata indicating first characteristics of the image. The first validation processor performs a first comparison by comparing the metadata with configuration data indicating predetermined characteristics of images required for a particular use and provides first acceptability data indicating the image is unacceptable for the use in response to an unsuccessful first comparison. A second validation processor parses imaging metadata representing the image to identify image metadata indicating second characteristics of the image. The second validation processor performs a second comparison by comparing header data with configuration data indicating predetermined characteristics of images required for a particular use and provides second acceptability data indicating the image is unacceptable for the use in response to an unsuccessful second comparison. A data processor generates performance data using the first and second acceptability data indicating quality of images provided by the image provider.
