Abstract
The invention relates generally to systems and methods for a medical data marketplace where de-identified medical data can be offered for sale or licensing, and prospective customers can search for the medical data using various criteria. The marketplace facilitates clinical research activities, clinical trials, medical research, medical technology development, and the like, while preserving HIPAA privacy protections, and allows medical data owners to monetize the data in an efficient manner.
Core Innovation
The invention provides a medical data marketplace in which a database stores a plurality of de-identified medical data sets, and each de-identified medical data set is owned by a different data owner. A server is coupled to the database, and an interface is generated to allow a customer to submit a search request that includes at least one criteria. The system receives the search request, queries the database using the criteria to retrieve at least one matching medical data set, and displays the matching medical data set on the interface.
The marketplace workflow is tied to financial transaction facilitation between the respective data owner and the customer. The criteria used for search is selected from a group consisting of modality type, an equipment manufacturer, a body part, a study description, a protocol name, a requested procedure description, a scheduled procedure step description, and a keyword. Matching de-identified medical data sets are then presented to the customer as part of the marketplace exchange.
In certain embodiments, the system performs a de-identification process on diagnostic image sets to generate de-identified diagnostic image sets prior to marketplace search and display. The de-identification process is described as including sanitizing of medical reports and DICOM diagnostic images, including preservation of controlled re-identification capability through encrypted header/parsed document storage associated with a unique identification key.
The de-identification includes modality-specific sanitization profiles that use blackout zones for patient-information areas, with selectable steps such as preview/confirmation and quality control. The description further includes validation of sanitized images, including OCR and gradient-boundary/region-of-interest analysis, and handling of remaining content by clearing, blacking out, or re-encapsulating the sanitized output back into DICOM format for marketplace transmission.
Claims Coverage
The independent claims are directed to a medical data marketplace storing de-identified medical data sets, a marketplace that de-identifies diagnostic image sets and then enables searching, and a marketplace that de-identifies medical data sets and uses modality-specific de-identification profiles and sanitization validation. The main inventive features are marketplace system structure, customer search by defined criteria, display of matching de-identified datasets, and facilitation of a financial transaction, with additional de-identification of medical content in the image and medical data claims.
Medical data marketplace with de-identified medical data sets owned by different data owners
A system including a database storing a plurality of de-identified medical data sets, wherein each de-identified medical data set is owned by a different data owner; a server coupled to the database; and a computer-readable storage medium operably connected to a processor coupled to the server.
Customer search interface using defined criteria group
Generate an interface that allows a customer to submit a search request that includes at least one criteria selected from a group consisting of a modality type, an equipment manufacturer, a body part, a study description, a protocol name, a requested procedure description, a scheduled procedure step description, and a keyword; receive the search request; and query the database using the criteria to retrieve at least one matching medical data set from the plurality of de-identified medical data sets.
Display of matching de-identified medical data sets and facilitation of financial transaction
Display the at least one matching medical data set on the interface and facilitate a financial transaction related to the at least one matching medical data set between a respective data owner and the customer.
De-identification of diagnostic image sets prior to marketplace search and display
A system including a database storing a plurality of diagnostic image sets, wherein each diagnostic image set is owned by a different data owner; a server coupled to the database; and a computer-readable storage medium operably connected to a processor coupled to the server, where the instructions cause the processor to perform a de-identification process on each of the plurality of diagnostic image sets to generate a plurality of de-identified diagnostic image sets.
Marketplace search, display, and financial transaction for de-identified diagnostic image sets
Generate an interface that allows a customer to submit a search request that includes at least one criteria selected from a group consisting of a modality type, an equipment manufacturer, a body part, a study description, a protocol name, a requested procedure description, a scheduled procedure step description, and a keyword; receive the search request; query the database using the criteria to retrieve at least one matching diagnostic image set from the plurality of de-identified diagnostic image sets; display the at least one matching diagnostic image set on the interface; and facilitate a financial transaction related to the at least one matching diagnostic image set between a respective data owner and the customer.
De-identification of medical data sets prior to marketplace search and display
A system including a database storing a plurality of medical data sets, wherein each medical data set is owned by a different data owner; a server coupled to the database; and a computer-readable storage medium operably connected to a processor coupled to the server, where the instructions cause the processor to perform a de-identification process on each of the plurality of medical data sets to generate a plurality of de-identified medical data sets.
Marketplace search, display, and financial transaction for de-identified medical data sets
Generate an interface that allows a customer to submit a search request that includes at least one criteria selected from a group consisting of a modality type, an equipment manufacturer, a body part, a study description, a protocol name, a requested procedure description, a scheduled procedure step description, and a keyword; receive the search request; query the database using the criteria to retrieve at least one matching medical data set from the plurality of de-identified medical data sets; display the at least one matching medical data set on the interface; and facilitate a financial transaction related to the at least one matching medical data set between a respective data owner and the customer.
Modality-specific de-identification profiles with blackout zones
Performing a de-identification process includes determining a modality for a medical image, obtaining a modality-specific de-identification profile indicating patient-information areas, and using a sanitizing engine to apply a blackout zone to those areas to delete the patient information.
Sanitization validation using diagnostic boundary and handling remaining pixels via DICOM format encapsulation
Detecting a diagnostic boundary when no characters are found after a blackout zone, checking for non-black pixels outside that boundary, and then either converting those outside pixels to black or encapsulating the image into a DICOM format if none are detected outside the boundary.
Across the independent claims, the invention centers on a medical data marketplace system that stores de-identified medical data sets or de-identifies diagnostic image sets and medical data sets, provides a customer search interface using a defined criteria group, displays matching de-identified results, and facilitates a financial transaction between data owner and customer. Dependent claim refinements add modality-specific de-identification profiles with blackout zones and validation and handling logic for remaining content, including conversion to black or encapsulation into DICOM format.
