Storing and retrieving large images via DICOM
Systems, methods, and media for storing a digital image using the Digital Imaging and Communication in Medicine (DICOM) standard. In an embodiment, a digital image at a first resolution is divided into a plurality of regions. Each of the plurality of regions is stored as a separate DICOM image file. In addition, each of the DICOM image files is associated with a DICOM series representing the digital image at the first resolution.
1. A system for storing a digital image using the Digital Imaging and Communication in Medicine (DICOM) standard, the system comprising:
at least one processor; and
one or more software modules configured to, when executed by the at least one processor,
operate an image capture device and acquire digital slide image data representative of a physical slide specimen,
divide the digital slide image data at a first resolution into a first plurality of regions and create a plurality of first DICOM images from each of said first plurality of regions,
divide the digital slide image data at a second resolution into a second plurality of regions and create a plurality of second DICOM images from each of said second plurality of regions, and
associate the plurality of first DICOM images and the plurality of second DICOM images with a DICOM study representing the digital image at a plurality of resolutions and store the DICOM study in a non-transitory computer readable medium.
2. The system of claim 1 , wherein the one or more modules are configured to capture a plurality of digital slide images, and 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 system of claim 1 , wherein the one or more modules are further configured to receive a request for the digital slide image at the first resolution and in response to the request, retrieve one or more of the first DICOM images.
4. The system of claim 1 , wherein a first one of the plurality of first DICOM images has a different dimension than a second one of the plurality of first DICOM images.
5. The system of claim 1 , wherein the one or more modules are further configured to store alignment information in one or more headers of the plurality of first DICOM images and the plurality of second DICOM images in the DICOM study.
6. The system of claim 5 , wherein the one or more modules are further configured to receive a request for the digital image at the first resolution and in response to the request, retrieve two or more of the plurality of first DICOM image files and align the two or more of the plurality of first DICOM image files based on the alignment information.
7. A method for storing a digital image using the Digital Imaging and Communication in Medicine (DICOM) standard, wherein the method comprises for each of one or more digital images, using at least one hardware processor to:
obtain a first plurality of regions of the digital image at a first resolution;
identify each region in the first plurality of regions as one of a plurality of first DICOM images;
obtain a second plurality of regions of the digital image at a second resolution;
identify each region in the second plurality of regions as one of a plurality of second DICOM images;
associate the plurality of first DICOM images and the plurality of second DICOM images as a DICOM study representing the digital image at a plurality of resolutions; and
storing the DICOM study in a non-transitory computer readable medium.
8. The method of claim 7 , further comprising using the at least one processor to associate a first DICOM study and a second DICOM study with a DICOM case for a single patient.
9. The method of claim 7 , further comprising using the at least one processor to store alignment information in one or more headers of the plurality of first DICOM images and the plurality of second DICOM images in the DICOM study.
10. The method of claim 7 , further comprising using the at least one processor to receive a request for the digital image at the first resolution and in response to the request, retrieve two or more of the plurality of first DICOM image files and align the two or more of the plurality of first DICOM image files based on the alignment information.
11. A non-transitory computer-readable medium having instructions stored thereon, wherein the instructions, when executed by a processor, cause the processor to:
operate an image capture device and acquire digital slide image data representative of a physical slide specimen;
divide the digital slide image data at a first resolution into a first plurality of regions and create a plurality of first DICOM images from each of said first plurality of regions;
divide the digital slide image data at a second resolution into a second plurality of regions and create a plurality of second DICOM images from each of said second plurality of regions; and
associate the plurality of first DICOM images and the plurality of second DICOM images with a DICOM study representing the digital image at a plurality of resolutions and store the DICOM study in a non-transitory computer readable medium.
12. The medium of claim 11 , wherein the instructions, when executed by a processor, cause the processor to capture a plurality of digital slide images, and 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.
13. The medium of claim 11 , wherein the instructions, when executed by a processor, cause the processor to receive a request for the digital slide image at the first resolution and in response to the request, retrieve one or more of the first DICOM images.
14. The medium of claim 11 , wherein a first one of the plurality of first DICOM images has a different dimension than a second one of the plurality of first DICOM images.
15. The medium of claim 11 , wherein the instructions, when executed by a processor, cause the processor to store alignment information in one or more headers of the plurality of first DICOM images and the plurality of second DICOM images in the DICOM study.
16. The medium of claim 11 , wherein the instructions, when executed by a processor, cause the processor to receive a request for the digital image at the first resolution and in response to the request, retrieve two or more of the plurality of first DICOM image files and align the two or more of the plurality of first DICOM image files based on the alignment information.
