7. The method according to claim 5 wherein the warning message is displayed in a pop-up window that appears on a display of a local computer coupled to the plurality of respective local servers.

8. The method according to claim 7 , wherein the pop-up window includes

a countdown timer that indicates a remaining time before the local severs will automatically execute the update file to update the medical synchronization application, and

an additional warning message that notifies the user that the medical synchronization application will be automatically shut down when the countdown timer expires.

9. The method according to claim 5 , wherein the request to update the medical synchronization application cannot be canceled once the cloud server executes the request.

10. The method according to claim 1 , wherein

each of the local servers is coupled to a local computer with a display, and

the local computer is coupled to a modality in a medical facility.

11. The method according to claim 1 , wherein the cloud repository on the cloud server is a repository for a cloud-based Picture Archiving and Communication System (PACS).

12. A non-transitory computer-readable medium (CRM) storing instructions that cause a cloud server coupled to a computer to perform an operation to update a system that synchronizes medical data between a cloud repository on the cloud server and a plurality of local repositories on a plurality of local servers of healthcare facilities connected to the cloud server, the operation comprising:

receiving, by the cloud server, a request to update a medical synchronization application stored on the cloud server and each of the local servers using an update file;

determining, by the cloud server, a version information of the medical synchronization application on all of the local servers; and

executing, by the cloud sever, the update file to update the medical synchronization application on the cloud server only in the event that cloud server determines that the medical synchronization application of all of the local servers have been updated; and

in response to one of the plurality of local servers establishing a connection with the cloud server, causing the cloud server to:

determine the version information of the medical synchronization application of the local server establishing the connection; and

in the event that the version information of the medical synchronization application of the local server establishing the connection is different from the version information of the medical synchronization application on the cloud server, transmit an instruction to update the medical synchronization application to the local server establishing the connection, wherein

the instruction includes the update file; and

in response to one of the plurality of local servers re-establishing a connection with the cloud server after being disconnected from the cloud server, causing the cloud server to:

determine the version information of the medical synchronization application on the local server establishing the connection; and

in the event that the version information of the medical synchronization application on the local server re-establishing the connection is different from the version information of the medical synchronization application on the cloud server, transmit the instruction to update the medical synchronization application to the local server re-establishing the connection.

13. The CRM according to claim 12 , wherein the local server establishing or re-establishing the connection to the cloud server is permitted to synchronize medical data with the cloud server only if the version information of the medical synchronization application on the local server establishing or re-establishing the connection is the same as the version information of the medical synchronization application on the cloud server.

14. The CRM according to claim 12 , wherein

the update file is stored in the cloud repository, and

the cloud server is first out of all of the cloud server and the local servers to execute the update file.

15. A system that synchronizes medical data, comprising:

a cloud server comprising a hardware processor;

a cloud repository comprising a memory on the cloud server; and

a plurality of local repositories on a plurality of local servers of healthcare facilities connected to the cloud server, wherein

the cloud server:

receives a request to update a medical synchronization application stored on the cloud server and each of the local servers using an update file,

determines, a version information of the medical synchronization application on all of the local servers, and

executes the update file to update the medical synchronization application on the cloud server only in the event that cloud server determines that the medical synchronization application of all of the local servers have been updated,

in response to one of the plurality of local servers establishing a connection with the cloud server, the cloud server:

determines the version information of the medical synchronization application of the local server establishing the connection, and

in the event that the version information of the medical synchronization application of the local server establishing the connection is different from the version information of the medical synchronization application on the cloud server, transmits an instruction to update the medical synchronization application to the local server establishing the connection,

the instruction includes the update file; and

in response to one of the plurality of local servers re-establishing a connection with the cloud server after being disconnected from the cloud server, the cloud server:

determines the version information of the medical synchronization application on the local server establishing the connection; and

in the event that the version information of the medical synchronization application on the local server re-establishing the connection is different from the version information of the medical synchronization application on the cloud server, transmits the instruction to update the medical synchronization application to the local server re-establishing the connection.

16. The system according to claim 15 , wherein the local server establishing or re-establishing the connection to the cloud server is permitted to synchronize medical data with the cloud server only if the version information of the medical synchronization application on the local server establishing or re-establishing the connection is the same as the version information of the medical synchronization application on the cloud server.
