Abstract

A system for computer-aided triage includes a router, a remote computing system, and a client application. A method for computer-aided triage includes receiving a data packet associated with a patient and taken at a point of care; checking for a suspected condition associated with the data packet; in an event that the suspected condition is detected, determining a recipient based on the suspected condition; and transmitting information to a device associated with the recipient.

Claims (27)

1. A method for automatically detecting a potential ischemic condition, the method comprising:

receiving a first set of images associated with a patient;

producing a mirror image version of each of the set of images, thereby producing a mirrored set of images;

overlaying the mirrored set of images with the first set of images, thereby producing a set of overlaid images;

automatically detecting the potential ischemic condition with a model, wherein the model receives as input the first set of images and the set of overlaid images.

2. The method of claim 1 , further comprising, in response to detecting the potential ischemic condition, automatically determining a specialist associated with a treatment of a potential ischemic condition.

3. The method of claim 2 , further comprising notifying the specialist on a device associated with the specialist.

4. The method of claim 3 , wherein the device is at least one of a mobile user device and a workstation.

5. The method of claim 2 , wherein the first set of images is taken at a first point of care and wherein the specialist is associated with a second point of care.

6. The method of claim 1 wherein the model is a machine learning model.

7. The method of claim 1 , wherein the ischemic condition is an ischemic core.

8. The method of claim 1 , further comprising, with the model, segmenting an ischemic region from the first set of images, wherein the potential ischemic condition is determined based on the ischemic region.

9. The method of claim 1 , wherein automatically detecting the potential ischemic condition supplements a standard radiology workflow.

10. A method for automatically detecting a potential ischemic condition, the method comprising:

receiving a first set of images associated with a patient;

processing the first set of images with a model, wherein processing the set of images comprises segmenting an ischemic region corresponding to the ischemic condition, and wherein a set of inputs of the model comprises the first set of images and a mirrored version of the first set of images; and

automatically detecting the potential ischemic condition based on the segmented ischemic region.

11. The method of claim 10 , wherein the ischemic condition is an ischemic core.

12. The method of claim 10 , wherein the model is a machine learning model.

13. The method of claim 12 , wherein the machine learning model is a deep learning model.

14. The method of claim 10 , further comprising, in response to detecting the potential ischemic condition, automatically triggering the transmission of a notification to a device.

15. The method of claim 14 , wherein the notification comprises a compressed version of at least one of the first set of images.

16. The method of claim 15 , wherein the at least one of the first set of images corresponds to a maximum cross section of the ischemic region.

17. The method of claim 14 , wherein the device is associated with a specialist at a first point of care.

18. The method of claim 17 , wherein the first set of images is taken at a second point of care remote from the first point of care.

19. The method of claim 18 , wherein the device is a mobile user device.

20. The method of claim 10 , wherein automatically detecting the potential ischemic condition supplements a standard radiology workflow.
