Class MergeCompositeContext


  • public class MergeCompositeContext
    extends java.lang.Object

    A class containing an application for merging the patient composite context of multiple instances for consistency.

    Patient identity is determined by being within the same study (having the same Study Instance UID), or referencing each others SOP Instance UIDs.

    It is assumed that one patient's instances can only cross-reference those of the same patient and not other patients. If there are no instance cross-references, then no commonality can be established across studies and no contexts are merged across studies.

    There is no assumption that any particular patient entity level key is the same (e.g., Patient ID).

    Various known dummy values are treated as if they were zero length or absent if conflicting with non-dummy values.

      • main

        public static void main​(java.lang.String[] arg)

        Merge the patient composite context of multiple instances for consistency.

        The files are processed in the order in which they are specified on the command line, and when there is a conflict, the first values are used. This can be used to make sure that all PatientIDs, for example are coerced to those first specified.

        For example, if a folder of images for multiple patients is specified first, and then a folder of structured reports or presentation states referencing (some of) those images but with different patient level identifiers is specified second, then the latter (the reports or presentation states) will be cooerced to have the same patient context as the former (the images).

        Parameters:
        arg - array of 2 or more strings - one or more source folder or DICOMDIR (to merge and use as a source of context), and a destination folder
