Abstract

An MRI image processing and analysis system may identify instances of structure in MRI flow data, e.g., coherency, derive contours and/or clinical markers based on the identified structures. The system may be remotely located from one or more MRI acquisition systems, and perform: error detection and/or correction on MRI data sets; segmentation; visualization of flow superimposed on anatomical structure, quantification; verification; and/or generation of patient specific 4-D flow protocols. A protected health information (PHI) service is provided which de-identifies medical study data and allows medical providers to control PHI data, and uploads the de-identified data to an analytics service provider (ASP) system. A web application is provided which merges the PHI data with the de-identified data while keeping control of the PHI data with the medical provider. A Trusted Broker Service (TBS) is integrated with the PHI service pipeline and allows an authorized third party to control access to data that has been uploaded to the ASP from an authorized uploader.

Claims (63)

1. A method of operating a medical analytics platform, the medical analytics platform including an analytics service provider (ASP) system, the method comprising:

receiving, by at least one processor of the ASP system, a request from a medical study data uploader (MSDU) system for an authentication token and an address of a trusted broker service (TBS) system;

storing, by at least one processor of the ASP system, the unique identifier of the medical study data on the ASP system;

sending, by at least one processor of the ASP system to the TBS system, a request for access instructions for the received medical study data, wherein the request includes the unique identifier of the medical study data;

receiving, by at least one processor of the ASP system from the TBS system, the access instructions in response to the request for access instructions, wherein the access instructions include a pre-signed, time-expiring access uniform resource locator (URL) generated by the TBS system with an associated access policy; and

storing, by at least one processor of the ASP system, the medical study data using the received access instructions by at least uploading the medical study data to the pre-signed, time-expiring access URL according to the associated access policy.

2. The method of claim 1 wherein the access instructions include encryption information for encrypting the medical study data and wherein the storing the medical study data includes encrypting the medical study data for storage using the encryption information.

3. The method of claim 1 further comprising:

receiving, by at least one processor of the ASP system, a request from a client processor-based device for the medical study data;

retrieving, by at least one processor of the ASP system, the unique identifier of the medical study data from storage on the ASP system in response to receiving the request for the medical study data;

sending, by at least one processor of the ASP system, a request for retrieval access instructions for the medical study data, wherein the request for retrieval access instructions includes the unique identifier of the medical study data;

receiving, by at least one processor of the ASP system, the retrieval access instructions in response to the request for the retrieval access instructions;

accessing, by at least one processor of the ASP system, the medical study data using the received retrieval access instructions; and

sending, by at least one processor of the ASP system, the accessed medical study data to the client processor-based device in response to the request received from the client processor-based device.

4. The method of claim 3 wherein the retrieval access instructions include decryption information for decrypting the medical study data and wherein the accessing the medical study data includes decrypting the medical study data using the decryption information.

5. The method of claim 3 further comprising:

retrieving from storage on the ASP system, by at least one processor of the ASP system, a file name associated with the medical study data in response to receiving the request for the medical study data, wherein the retrieval access instructions include a pre-signed download uniform resource locator (URL) and wherein the accessing the medical study data includes requesting, by at least one processor of the ASP system, the medical study data at a location specified by the pre-signed download uniform URL.

6. The method of claim 1 , wherein the request from the MSDU includes an application programming interface (API) key and unique secret stored on the MSDU system, and wherein authenticating the request from the MSDU system is based on the API key and the unique secret.

7. The method of claim 1 wherein the MSDU system is part of a protected health information (PHI) system.

8. The method of claim 7 wherein the medical study data is de-identified medical study data that is de-identified by the PHI system.

9. A non-transitory computer-readable storage medium storing contents that, when executed by one or more processors of an analytics service provider (ASP) system, cause actions to be performed, the actions comprising:

receiving a request from a medical study data uploader (MSDU) system for an authentication token and an address of a trusted broker service (TBS) system;

authenticating the request from the MSDU system;

sending the authentication token and the address of the TBS system to the MSDU system based on authentication of the request from the MSDU system;

receiving a request from the TBS system for verification of the authentication token received from the MSDU system;

verifying the authentication token and sending verification of the authentication token to the TBS system;

receiving from the MSDU system, medical study data along with a unique identifier of the medical study data, wherein the unique identifier of the medical study data is generated by the TBS system;

storing the unique identifier of the medical study data on the ASP system;

sending to the TBS system, a request for access instructions for the received medical study data, wherein the request includes the unique identifier of the medical study data;

receiving from the TBS system, the access instructions in response to the request for access instructions, wherein the access instructions include a pre-signed, time-expiring access uniform resource locator (URL) generated by the TBS system with an associated access policy; and
