Abstract

A system and method for automatically handling data objects within groupings in a PACS network. Where a data object belonging to one grouping is moved to or copied into another grouping, certain associated data objects will automatically be moved or copied to the other grouping. Similarly, where some data objects are deleted from a grouping, data objects associated with objects which will not be deleted are automatically protected from deletion.

Claims

1. A clone management system for duplicating one or more data objects of a plurality of data objects, the plurality of data objects being stored as a first study in a DICOM database, the system comprising:

(a) a memory for storing the plurality of data objects;

(b) a processor coupled to the memory configured for;

(i) categorizing the plurality of data objects into a first category of manually selectable data objects and a second category of automatically selectable data objects;

(ii) receiving input defining an initial base set of manually selected data objects, wherein the initial base set of data objects comprises one or more data objects from the first category of manually selectable data objects;

(iii) duplicating the data objects in the initial base set, the duplicated initial base set being stored in a target study;

(iv) determining one or more automatically selected associated data objects from the second category of automatically selectable data objects, wherein the one or more associated data objects from the second category;

are not included in the duplicated initial base set, and

either reference the one or more data objects in the initial base set or are referenced by the one or more data objects in the initial base set;

(v) duplicating the one or more automatically selected associated data objects from the second category; and

(vi) storing the duplicated one or more automatically selected associated data objects from the second category in the target study.

2. The system of claim 1, wherein (iii) and (vi) include updating references between data objects in the target study by:

(A) selecting a data object in the target study having a reference to a data object from the first category of manually selectable data objects or the second category of automatically selectable data objects, the data object from the first category of manually selectable data objects or the second category of automatically selectable data objects having a duplicate in the target study;

(B) finding the duplicate of the data object from the first category of manually selectable data objects or the second category of automatically selectable data objects in the target study; and

(C) adding a reference from the selected data object in the target study to the duplicate of the data object in the target study.

3. The system of claim 1, wherein (iii) and (vi) include updating references between data objects in the target study by:

(A) selecting a data object in the target study having a reference to a data object from the first category of manually selectable data objects or the second category of automatically selectable data objects, the data object from the first category of manually selectable data objects or the second category of automatically selectable data objects having a duplicate in the target study;

(B) finding the duplicate of the data object from the first category of manually selectable data objects or the second category of automatically selectable data objects in the target study; and

(C) replacing the reference from the selected data object in the target study with a reference to the duplicate of the data object in the target study.

4. The system of claim 1, wherein said categorizing comprises placing data objects from a third category of data objects into the first category of manually selectable data objects or the second category of automatically selectable data objects, the third category of data objects comprising at least one semi-automatically selectable data object that needs to be examined to determine if the object can be handled automatically.

5. The system of claim 1, wherein the processor is further configured for:

(vii) marking a protected set of one or more data objects including data objects from the first category of manually selectable data objects which were not selected in (ii);

(viii) identifying one or more data objects from the second category of automatically selectable data objects which are not included in the protected set and are associated with one or more objects in the protected set;

(ix) adding the data objects identified in (viii) to the protected set;

(x) repeating (viii) to (ix) until no objects are identified in (viii); and

(xi) deleting objects from the plurality of data objects stored in the first study which are not in the protected set.

6. The system of claim 1, wherein the plurality of data objects stored in the first study is to be merged with at least one data object stored in the target study, the data objects selected in (ii) including all the data objects from the first category of manually selectable data objects selected to be merged with the at least one data object in the target study.

7. The system of claim 1, wherein a at least one of the plurality of data objects stored in the first study has been selected to be split from the first study, wherein the data objects selected in (ii) include all the objects from the first category of manually selectable data objects selected to be split from the first study and the target study is initially empty.

8. The system of claim 1, wherein the plurality of data objects stored in the first study has been selected to be segmented into two or more studies and wherein (ii) to (vi) are repeated once for each of the two or more segmented studies and the data objects selected in (ii) in each iteration include all the objects from the first category of manually selectable data objects in the first study which have been selected to be segmented into the current segmented set and the target study defined in (ii) in each iteration is the current segmented study.

9. The system of claim 1, wherein the system operates in an image storage network, the image storage network being a PACS network.

10. The system of claim 1, wherein at least one data object in the first category of manually selectable data objects is selected from the group consisting of:

DICOM MG For Presentation objects, DICOM CT objects, DICOM MR objects, waveform objects, stand-alone overlay objects, and DICOM SR objects.

11. The system of claim 1, wherein at least one data object in the second category of automatically selectable data objects is selected from the group consisting of:

DICOM GSPS objects, DICOM CSPS objects, CAD SR objects and MG For Processing objects.
