Abstract

After selecting two or more image series for comparison, images of the image series are interleaved so that they are alternatively displayed in a comparison pane on a display device. In one embodiment, after one or more image series are selected for comparison, an interleaved image series is created containing each of the images of the one or more selected image series, or, alternatively, the interleaved image series comprises links to the images arranged in the interleaved pattern. If differences exist in the images of the multiple image series, these differences may be more easily detectable as the display device cycles between the images. Comparison of images in an interleaved image series may be more advantageous if the images of each selected image series are of a common anatomical area, common image size, and the images are in the same order.

Claims

1. A computer-implemented method comprising:

by one or more processors executing program instructions;

accessing a set of images comprising at least a first plurality of images of a first image series and a second plurality of images of a second image series;

determining values of a first characteristic associated with images of the set of images;

ordering the images of the set of images based at least in part on the values of the first characteristic associated with the images of the set of images to generate an ordered set of images;

determining a first value of a second characteristic associated with a first image of the set of images;

determining a second value of the second characteristic associated with a second image of the set of images, wherein the first image and the second image are adjacent to each other in the ordered set of images;

determining a difference between the first value and the second value of the second characteristic;

adjusting one or more characteristics of the first image or the second image based on the difference between the first value and the second value of the second characteristic;

in response to a first user input, causing display of the first image at a location of an electronic display; and

in response to a second user input, causing display of the second image at the location of the electronic display to replace the first image.

2. The computer-implemented method of claim 1, wherein the first characteristic comprises at least one of a time, a modality, an application of contrast agent, an anatomical position associated with the images of the set of images.

3. The computer-implemented method of claim 1, wherein the second characteristic is a display characteristic and adjusting the one or more characteristics of the first image or the second image comprises adjusting the display characteristic of the first image or the second image.

4. The computer-implemented method of claim 3, wherein the display characteristic comprises at least one of brightness, contrast, size, opacity map, rotation, location, zoom level, cropping, morphing, or color.

5. The computer-implemented method of claim 1, wherein ordering the images of the set of images is further based on at least one of a type of image, an area imaged, a clinical indication, a source of image, a display device, or a user.

6. The computer-implemented method of claim 1, wherein the first image series and the second image series are selected based on characteristics of the first or the second image series comprises at least one of:

a header information item, a filename, a modality, a name, an anatomical area, an image size, or an image orientation of the first or the second image series.

7. A computing system comprising:

an electronic display;

an input device;

a non-transitory computer-readable storage medium configured to store software instructions; and

one or more computer processors in communication with the electronic display, the input device, and the non-transitory computer-readable medium, the one or more computer processors configured to execute the software instructions in order to cause the computing system to;

access a set of images comprising at least a first plurality of images of a first image series and a second plurality of images of a second image series;

determine values of a first characteristic associated with images of the set of images;

order the images of the set of images based at least in part on the values of the first characteristic associated with the images of the set of images to generate an ordered set of images;

determine a first value of a second characteristic associated with a first image of the set of images;

determine a second value of the second characteristic associated with a second image of the set of images, wherein the first image and the second image are adjacent to each other in the ordered set of images;

determine a difference between the first value and the second value of the second characteristic;

adjust one or more characteristics of the first image or the second image based on the difference between the first value and the second value of the second characteristic;

in response to a first user input, causing display of the first image at a location of the electronic display; and

in response to a second user input, causing display of the second image at the location of the electronic display to replace the first image.

8. The computer system of claim 7, wherein the first characteristic comprises at least one of a time, a modality, an application of contrast agent, an anatomical position associated with the images of the set of images.

9. The computer system of claim 7, wherein the second characteristic is a display characteristic and adjusting the one or more characteristics of the first image or the second image comprises adjusting the display characteristic of the first image or the second image.

10. The computer system of claim 9, wherein the display characteristic comprises at least one of brightness, contrast, size, opacity map, rotation, location, zoom level, cropping, morphing, or color.

11. The computer system of claim 7, wherein ordering the images of the set of images is further based on at least one of a type of image, an area imaged, a clinical indication, a source of image, a display device, or a user.

12. The computer system of claim 7, wherein the first image series and the second image series are selected based on characteristics of the first or the second image series comprises at least one of:

a header information item, a filename, a modality, a name, an anatomical area, an image size, or an image orientation of the first or the second image series.

13. A non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by one or more processors to cause the one or more processors to:

access a set of images comprising at least a first plurality of images of a first image series and a second plurality of images of a second image series;

determine values of a first characteristic associated with images of the set of images;

order the images of the set of images based at least in part on the values of the first characteristic associated with the images of the set of images to generate an ordered set of images;

determine a first value of a second characteristic associated with a first image of the set of images;

determine a second value of the second characteristic associated with a second image of the set of images, wherein the first image and the second image are adjacent to each other in the ordered set of images;

determine a difference between the first value and the second value of the second characteristic;

adjust one or more characteristics of the first image or the second image based on the difference between the first value and the second value of the second characteristic;

in response to a first user input, causing display of the first image at a location of an electronic display; and

in response to a second user input, causing display of the second image at the location of the electronic display to replace the first image.

14. The non-transitory computer readable medium of claim 13, wherein the first characteristic comprises at least one of a time, a modality, an application of contrast agent, an anatomical position associated with the images of the set of images.
