Abstract

A digital image management system is described which facilitates image archival with a unique method for grouping customer images and information. As applied to medical environments, the system creates a virtual film jacket and implements the unique method by modeling convention hospital film archival procedures. The invention facilitates archival to a variety of devices including a redundant array of independent disks, magneto-optical storage devices and digital linear tapes and eliminates the need for hospital staff to retrieve several tapes from archive in order for a radiologist to review a patient'"'"'s study. The invention is applicable to any environment where customer images and information are continuously archived and retrieved.

Claims

1. A method for archiving a plurality of digital images, wherein each image is associated with one of a plurality of customers, the method comprising the steps of:

selecting one of the customers;

defining an image group to include all of the images associated with the selected customer;

storing the image group to a short-term storage device having a plurality of individually removable short-term storage media such that all of the images of the image group are maintained on a single short-term storage media;

moving the customer image group from said short-term storage device to a mid-term storage device having a plurality of individually removable mid-term storage media when the customer image group is not accessed by a user within a first predetermined period of time, wherein the mid-term storage device stores the customer image group on a single mid-term storage medium; and

moving the customer image group from the mid-term storage device to a long-term storage device having a plurality of individually removable long-term storage media when the customer image group is not accessed by a user within a second predetermined period of time, wherein the long-term storage device stores the customer image group on a single long-term storage medium.

2. The method of claim 1, wherein the storing step comprises the steps of:

receiving a request from the user to store an input image associated with the selected customer;

accessing the database to read a location of the customer image group associated with the selected customer;

retrieving the customer image group associated with the selected customer from the long-term storage device based on the location read from the database, wherein the retrieved image group is moved to a single short-term storage medium within the short-term storage device;

receiving the input image from an input imaging device; and

storing the received input image on the short-term storage medium having the retrieved customer image group, thereby adding the received image to the retrieved customer image group.

3. The method of claim 1, wherein the short-term storage device is a redundant array of independent disks.

4. The method of claim 1, wherein the mid-term storage device is a magneto-optical storage device.

5. The method of claim 1, wherein the long-term storage device is selected from one of 4 mm tape drive, 8 mm tape drive, and 9-track tape drive.

6. The method of claim 1, wherein the long-term storage device is a digital linear tape device holding a plurality of tapes.

7. The method of claim 2, wherein the retrieving step further comprises the steps of automatically informing a user to physically retrieve a long-term storage medium from a storage facility, and automatically informing the user to physically return the long-term storage medium to the storage facility when the image group is not accessed for a third predetermined period of time.

8. The method of claim 2, wherein the customer is a patient and the received input image is a medical diagnostic image produced by a medical modality.

9. The method of claim 2, wherein the received input image is generated by scanning a photograph.

10. The method of claim 2, wherein the received input image is generated by scanning a negative.

11. The method of claim 2, wherein the received input image is a digitized movie generated by digitizing information stored on a VHS tape.

12. The method of claim 2, wherein the customer image group further includes customer specific information other then the images associated with the customer.

13. The method of claim 12, wherein the customer is a patient and the input image is a medical diagnostic image produced by a medical modality, and further wherein the customer specific information includes at least one of the patient'"'"'s name, a physician'"'"'s name and a modality type for each image of the image group.

14. A digital information management system comprising:

an input imaging device for generating a plurality of images, wherein each image is associated with one of a plurality of customers;

a short-term storage device;

a mid-term storage device;

a long-term storage device;

a database maintaining an entry for each customer; and

a software system executing on a suitably configured computer for managing the plurality of images by performing the steps of;

selecting one of the customers;

defining a customer image group to include all of the images associated with the selected customer;

commanding a short-term storage device having a plurality of individually removable short-term storage media to store all of the images of the customer image group on a single short-term storage medium;

moving the customer image group from said short-term storage device to a mid-term storage device having a plurality of individually removable mid-term storage media when the customer image group is not accessed by a user within first predetermined period of time, wherein the mid-term storage device stores the customer image group on a single mid-term storage medium; and

moving the customer image group from the short-term storage device to a long-term storage device having a plurality of individually removable long-term storage media when the customer image group is not accessed by a user within a second predetermined period of time, wherein the long-term storage device stores the images of the customer image group on a single long-term storage medium.

15. The digital information management system of claim 14, wherein the commanding step of the software program comprises the steps of:

receiving a request from the user to store an input image associated with the selected customer;

accessing the database to read a location of the customer image group associated with the selected customer;

retrieving the customer image group associated with the selected customer from the long-term storage device based on the location read from the database, wherein the retrieved image group is moved to a single short-term storage medium within the short-term storage device;

receiving the input image from an input imaging device; and

storing the received input image on the short-term storage medium having the retrieved customer image group, thereby adding the received image to the retrieved customer image group.

16. The digital information management system of claim 14, wherein the short-term storage device is a redundant array of independent disks.

17. The digital information management system of claim 14, wherein the mid-term storage device is a magneto-optical storage device.

18. The digital information management system of claim 14, wherein the long-term storage device is selected from one of 4 mm tape drive, 8 mm tape drive, and 9-track tape drive.

19. The digital information management system of claim 15, wherein the long-term storage device is a digital linear tape device holding a plurality of tapes.

20. The digital information management system of claim 19, wherein the software system automatically informs a user to physically retrieve a tape from a tape archive, and further wherein the moving step further comprises the step of automatically informing the user to physically return the tape to the archive.

21. The digital information management system of claim 14, wherein the customer is a patient and the input imaging device is a medical modality that produces medical diagnostic images.

22. The digital information management system of claim 15, wherein the input imaging device produces an input image by scanning a photograph.

23. The digital information management system of claim 15, wherein the input imaging device produces an input image by scanning a negative.

24. The digital information management system of claim 15, wherein the input image is a digitized movie and wherein the input image device produces an input image by digitizing information stored on a VHS tape.
