Systems and methods for data storage

A system for accessing medical image data, comprising:

• at least one storage device including a set of instructions;
• and
• at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor is directed to cause the system to perform operations including:
• obtaining, by the at least one processor, from a user terminal, a request for accessing a medical image file, wherein the medical image file includes a plurality of image slices, and the medical image file is generated from a medical imaging device;
• obtaining, by the at least one processor, from a first storage device, metadata of the medical image file based on the request, wherein the metadata of the medical image file includes index information of the plurality of image slices, wherein the index information of the plurality of image slices is determined by:
• identifying, by the at least one processor, a series instance unique identifier (UID) of the plurality of image slices;
• and
• determining, by the at least one processor, the index information of the plurality of image slices based on the series instance UID, wherein the index information includes a hash value for each of the plurality of image slices, wherein the determining, by the at least one processor, the index information of the plurality of image slices based on the series instance UID includes:
• determining a hash value of a first image slice which is immediately next to a second image slice of the plurality of image slices based on a hash value of the second image slice;
• obtaining, by the at least one processor, from the first storage device, access information of at least one second storage device that stores image data of the medical image file based on the metadata, wherein the first storage device is different from each of the at least one second storage device;
• obtaining, by the at least one processor, from the at least one second storage device, at least one sub-image data set of the image data;
• and
• obtaining, by the at least one processor, the medical image file by combining the metadata and the at least one sub-image data set.
