Abstract

Some embodiments of a workflow management system to process medical image data generated by a medical imaging device have been presented. In one embodiment, a user selects a workflow template with a predefined set of image processing stages, and applies the workflow template to the medical image data. Each of the predefined set of image processing stages in the workflow template includes one or more image processing operations. Each of the image processing operations is capable of generating metadata for processing the medical image data. The medical image data is then processed through each of the predefined image processing stages. The result of processing is a collection of metadata. Each metadata in the collection can be applied to the medical image data to generate a medical image view.
