Abstract

Methods and systems for rending medical images within a web browser application. The web browser application retrieves a worklist and automatically determines an image study from the worklist to be cached. The web browser application retrieves at least one medical image included in the image study. The web browser application creates a web database for storing the at least one medical image within the browser application. When a user selects a medical image for display within the web browser, the web browser application determines whether the medical image is stored in the web database. When the medical image is stored in the web database, the web browser application retrieves the medical image from the web database. When the medical image is not stored in the web database, the web browser application retrieves the medical image from a remote image repository.

First claim

What is claimed is:

1. A method for rendering medical images within a web browser application, the method comprising:
prior to receiving user input selecting a medical image for display:
retrieving, with an electronic processor executing the web browser application, a worklist associated with a user identifier, the worklist including a unique identifier for each of a plurality of image studies;
automatically determining, with the electronic processor executing the web browser application, at least one of the plurality of image studies from the worklist to be cached;
creating, with the electronic processor executing the web browser application, a web database for storing data within the web browser application, the web database embedded within the web browser application; and
pre-downloading at least one medical image included in the at least one of the plurality of image studies to the web database for use as a cache for subsequent user requests by:
retrieving, with the electronic processor executing the web browser application, the at least one medical image included in the at least one of the plurality of image studies from a remote image repository over at least one communication network and storing, with the electronic processor executing the web browser application, the at least one medical image in the web database; and

after pre-downloading the at least one medical image:
receiving, with the electronic processor executing the web browser application, the user input selecting the medical image from the worklist for display within the web browser application,
determining, with the electronic processor executing the web browser application, whether the medical image selected via the user input is stored in the web database, and
in response to the medical image selected via the user input being stored in the web database, retrieving, with the electronic processor executing the web browser application, the medical image from the web database and displaying the medical image on a display device.

2. The method of claim 1 , further comprising retrieving the user identifier from a user via the web browser application.

3. The method of claim 1 , wherein retrieving the worklist includes retrieving the worklist from at least one selected from a group consisting of the remote image repository, a routing server associated with the remote image repository, a storage device of an electronic device including the electronic processor, or a combination thereof.

4. The method of claim 1 , wherein automatically determining the at least one of the plurality of image studies includes selecting a subset of the plurality of image studies included in the worklist.

5. The method of claim 1 , wherein automatically determining the at least one of the plurality of image studies includes selecting the plurality of image studies.

6. The method of claim 1 , wherein automatically determining the at least one of the plurality of image studies includes selecting a most recent image study of the plurality of image studies.

7. The method of claim 1 , wherein storing the at least one medical image in the web database includes storing each of a plurality of medical images included in the at least one of the plurality of image studies in the web database sequentially.

8. The method of claim 1 , wherein creating the web database includes opening a previously-created web database.

9. The method of claim 1 , wherein retrieving the medical image from the remote image repository includes sending an image identifier associated with the medical image to a routing server associated with the remote image repository.

10. A non-transitory computer-readable medium containing instructions that, when executed by an electronic processor, perform a set of functions, the set of functions comprising:
prior to receiving user input selecting a medical image for display:
retrieving, with a web browser application, a worklist associated with a user identifier, the worklist including a unique identifier for each of a plurality of image studies;
automatically determining, with the web browser application, at least one of the plurality of image studies from the worklist to be cached;
creating, with the web browser application, a web database for storing data within the web browser application, the web database embedded within the web browser application; and
pre-downloading at least one medical image included in the at least one of the plurality of image studies to the web database for use as a cache for subsequent user requests by:
retrieving, with the web browser application, the at least one medical image included in the at least one of the plurality of image studies from a remote image repository over at least one communication network and storing, with the electronic processor executing the web browser application, the at least one medical image in the web database; and

after pre-downloading the at least one medical image:
receiving, with the web browser application, the user input selecting the medical image from the worklist for display within the web browser application,
determining, with the web browser application, whether the medical image selected via the user input is stored in the web database, and
in response to the medical image selected via the user input being stored in the web database, retrieving, with the web browser application, the medical image from the web database and displaying the medical image on a display device.

11. The non-transitory computer-readable medium of claim 10 , wherein retrieving the worklist includes retrieving the worklist from at least one selected from a group consisting of the remote image repository, a routing server associated with the remote image repository, a storage device of an electronic device including the electronic processor, or a combination thereof.

12. The non-transitory computer-readable medium of claim 10 , wherein storing the at least one medical image in the web database includes storing each of a plurality of medical images included in the at least one of the plurality of image studies in the web database sequentially.

13. An electronic device for rendering medical images from a remote image repository, the electronic device comprising:
a memory storing instructions; and
an electronic processor coupled to the memory and configured to execute the instructions to implement a web browser application, the web browser application configured to:

prior to receiving user input selecting a medical image for display:
retrieve a worklist associated with a user identifier, the worklist including a unique identifier for each of a plurality of image studies;
automatically determine at least one of the plurality of image studies from the worklist to be cached;
create a web database, the web database embedded within the web browser application; and
pre-download at least one medical image included in the at least one of the plurality of image studies to the web database for use as a cache for subsequent user requests by:
retrieving the at least one medical image included in the at least one of the plurality of image studies from the remote image repository over at least one communication network, and storing the at least one medical image in the web database; and

after pre-downloading the at least one medical image:
receive the user input selecting the medical image for display from the worklist within the web browser application, determine whether the medical image selected via the user input is stored in the web database, and in response to the medical image selected via the user input being stored in the
