store each of the first plurality of regions as a separate first DICOM images;
associate each of the first DICOM images with a first DICOM series representing the digital image at the first resolution;
obtain the digital image at a second resolution that is different than the first resolution;
divide the digital image at the second resolution into a second plurality of regions;
store each of the second plurality of regions as a separate second DICOM images;
associate each of the second DICOM images with a second DICOM series representing the digital image at the second resolution; and
associate the first DICOM series and the second DICOM series with a DICOM study representing the digital image at a plurality of resolutions.
2. The non-transitory computer-readable medium of claim 1 , wherein the one or more digital images comprises a plurality of digital images, and wherein the instructions further cause the processor to associate a first DICOM study, representing a first one of the plurality of digital images at a plurality of resolutions, and a second DICOM study, representing a second one of the plurality of digital images at a plurality of resolutions, with a DICOM case representing a plurality of digital images for a single patient.
3. The non-transitory computer-readable medium of claim 1 , wherein the instructions further cause the processor to:
receive a request for the digital image at the first resolution; and,
in response to the request, retrieve one or more of the first DICOM images.
4. The non-transitory computer-readable medium of claim 1 , wherein one or more of the first DICOM images have a different dimension than one or more other ones of the first DICOM image files.
5. The non-transitory computer-readable medium of claim 1 , wherein the instructions further cause the processor to store alignment information for the first plurality of regions in one or more headers for one or more of the first DICOM images and the first DICOM series.
6. The non-transitory computer-readable medium of claim 5 , wherein the instructions further cause the processor to:
receive a request for the digital image at the first resolution; and,
in response to the request, retrieve a plurality of the first DICOM images, and align at least a portion of the plurality of first DICOM images based on the alignment information.
7. A system for storing a digital image using the Digital Imaging and Communication in Medicine (DICOM) standard, the system comprising:
at least one hardware processor; and
one or more modules that, when executed by the at least one hardware processor, for each of one or more digital images,
divide the digital image at a first resolution into a first plurality of regions,
store each of the first plurality of regions as a separate first DICOM images,
associate each of the first DICOM images with a first DICOM series representing the digital image at the first resolution,
obtain the digital image at a second resolution that is different than the first resolution,
divide the digital image at the second resolution into a second plurality of regions,
store each of the second plurality of regions as a separate second DICOM images,
associate each of the second DICOM images with a second DICOM series representing the digital image at the second resolution, and
associate the first DICOM series and the second DICOM series with a DICOM study representing the digital image at a plurality of resolutions.
8. The system of claim 7 , wherein the one or more digital images comprise a plurality of digital images, and wherein the one or more modules further associate a first DICOM study, representing a first one of the plurality of digital images at a plurality of resolutions, and a second DICOM study, representing a second one of the plurality of digital images at a plurality of resolutions, with a DICOM case representing a plurality of digital images for a single patient.
9. The system of claim 7 , wherein the one or more modules further:
receive a request for the digital image at the first resolution; and,
in response to the request, retrieve one or more of the first DICOM image files.
10. The system of claim 7 , wherein one or more of the first DICOM image files have a different dimension than one or more other ones of the first DICOM image files.
11. The system of claim 7 , wherein the one or more modules further store alignment information for the first plurality of regions in one or more headers for one or more of the first DICOM images and the first DICOM series.
12. The system of claim 11 , wherein the one or more modules further:
receive a request for the digital image at the first resolution; and,
in response to the request, retrieve a plurality of the first DICOM image files, and align at least a portion of the plurality of first DICOM image files based on the alignment information.
13. A method for storing a digital image using the Digital Imaging and Communication in Medicine (DICOM) standard, wherein the method comprises using at least one hardware processor to, for each of one or more digital images:
divide the digital image at a first resolution into a first plurality of regions;
store each of the first plurality of regions as a separate first DICOM images;
associate each of the first DICOM images with a first DICOM series representing the digital image at the first resolution;
obtain the digital image at a second resolution that is different than the first resolution;
divide the digital image at the second resolution into a second plurality of regions;
store each of the second plurality of regions as a separate second DICOM images;
associate each of the second DICOM images with a second DICOM series representing the digital image at the second resolution; and
associate the first DICOM series and the second DICOM series with a DICOM study representing the digital image at a plurality of resolutions.
14. The method of claim 13 , wherein the one or more digital images comprise a plurality of digital images, and wherein the method further comprising using the at least one hardware processor to associate a first DICOM study, representing a first one of the plurality of digital images at a plurality of resolutions, and a second DICOM study, representing a second one of the plurality of digital images at a plurality of resolutions, with a DICOM case representing a plurality of digital images for a single patient.
15. The method of claim 13 , further comprising using the at least one hardware processor to:
receive a request for the digital image at the first resolution; and,
in response to the request, retrieve one or more of the first DICOM image files.
16. The method of claim 13 , wherein one or more of the first DICOM image files have a different dimension than one or more other ones of the first DICOM image files.
