Abstract

An image viewer and method for using the same in a medical image management system are described. In one embodiment, the system comprises: a network communication interface to receive compressed image pixel data; an image cache memory to cache the compressed DICOM image pixel data and rendered images; one or more processors coupled to the network connection interface and the memory and configured to implement an image rendering pipeline to perform image rendering in response to opening a healthcare study for review, wherein the image rendering includes determining whether compressed image pixel data associated with an image selected for display is in an image cache memory, and if so, then fetching the compressed image pixel data from an image cache, where the image pixel data represents a pre-rendered version of an image from a series in the healthcare study, and rendering a displayable image for display with a viewer on the display, and if not, then downloading from a remote location a version of the displayable image for display with the viewer; and a display coupled to the one or more processors to display the displayable image with a viewer.

Claims

1. A system comprising:

a network communication interface to receive compressed image pixel data;

an image cache memory to cache the compressed DICOM image pixel data and rendered images;

one or more processors coupled to the network connection interface and the memory and configured to implement an image rendering pipeline to perform image rendering in response to opening a healthcare study for review, wherein the image rendering includes determining whether compressed image pixel data associated with an image selected for display is in an image cache memory, and if so, then

fetching the compressed image pixel data from an image cache, the image pixel data representing a pre-rendered version of an image from a series in the healthcare study,

decompressing the compressed image pixel data to obtain the image pixel data,

performing one or more image processing operations on the image pixel data,

generating a displayable image from the image pixel data that has undergone image processing, and

rendering the displayable image for display with a viewer on the display, and if not, then downloading from a remote location a version of the displayable image for display with the viewer;

a display coupled to the one or more processors to display the displayable image with the viewer.

2. The system defined in claim 1 wherein the processor is further operable to request compressed image pixel data from a server remotely located with respect to the system via the network connection and download the compressed image pixel data into the image cache.

3. The system defined in claim 2 wherein the processor is further operable to:

generate and queue the request in response to the healthcare study being opened;

send, using a loader, the request to the remotely located server; and

receive and store in the image cache the compressed image pixel data received from the remotely located server.

4. The system defined in claim 3 wherein the processor requests the compressed image pixel data from the server in response to determining the compressed image pixel data is not stored in the image cache.

5. The system defined in claim 4 wherein the compressed image pixel data is requested by the processor based on a priority.

6. The system defined in claim 5 wherein compressed image pixel data associated with an image that is part of a series selected for display on the display has a higher priority and is requested before compressed image pixel data associated with an image that is not part of the series selected for display on the display.

7. The system defined in claim 1 wherein the processor is operable to request compressed image pixel data from an image cache over requesting the compressed image pixel data from a server remotely located from the server in order to compensate for a low network speed environment in which network speed is below a threshold.

8. The system defined in claim 1 wherein the image comprises a DICOM image.

9. The system defined in claim 1 wherein the processor is operable to download compressed image data to the image cache as a background process before the study is opened for review.

10. The system defined in claim 1 wherein the viewer is part of a browser.

11. A method for displaying images from a healthcare study in a graphical user interface (GUI), the method comprising:

determining whether compressed image pixel data associated with an image of a healthcare study selected for display is in an image cache memory of a medical image management system;

if the compressed image pixel data associated with an image of a healthcare study selected for display is in an image cache memory of a medical image management system, then

fetching the compressed image pixel data from an image cache, the image pixel data representing a pre-rendered version of an image from a series in the healthcare study,

decompressing the compressed image pixel data to obtain the image pixel data,

performing one or more image processing operations on the image pixel data,

generating a displayable image from the image pixel data that has undergone image processing, and

rendering the displayable image for display with a viewer on the display;

if the compressed image pixel data associated with an image of a healthcare study selected for display is not in an image cache memory of a medical image management system, then downloading from a remote location a version of the displayable image for display with the viewer; and

displaying the displayable image with the viewer.

12. The method defined in claim 11 further comprising requesting compressed image pixel data from a server remotely located with respect to the system via the network connection and downloading the compressed image pixel data into the image cache.

13. The method defined in claim 12 wherein downloading from a remote location a rendered version of the displayable image for display with the viewer comprises:

generating and queuing the request at the medical image management system in response to the study being opened;

sending, by a loader of the medical image management system, the request to the remotely located server; and

receiving and storing in the image cache, by the medical image management system, the compressed image pixel data received from the remotely located server.

14. The method defined in claim 11 wherein the compressed image pixel data is fetched based on a priority.

15. The method defined in claim 14 wherein compressed image pixel data associated with an image that is part of a series selected for display on the display has a higher priority and is requested before compressed image pixel data associated with an image that is not part of the series selected for display on the display.

16. The method defined in claim 11 wherein the image comprises a DICOM image.

17. The method defined in claim 11 wherein the viewer is part of a browser.

18. A non-transitory computer readable storage media having instructions stored thereupon which, when executed by a system having at least a processor and a memory therein, cause the system to perform a method for displaying images from a healthcare study in a graphical user interface (GUI), wherein the method comprises:
