Abstract

A medical scan artifact detection system is operable to receive, via a receiver, a medical scan of a patient. Artifact detection data is generated by executing an artifact detection function on the medical scan, where the artifact detection data indicates at least one artifact detected in the medical scan. A notification is transmitted, via a transmitter, a client device for display via a display device, where the notification indicates the at least one artifact.

First claim

What is claimed is:

1. A medical scan artifact detection system comprising:
at least one processor; and
a memory that stores operational instructions that, when executed by the at least one processor, cause the medical scan artifact detection system to:
receive, via a receiver, raw signal data of a medical scan of a patient as a data stream from a medical imaging machine as the medical scan is being captured;
generate artifact detection data by executing an artifact detection function on the raw signal data of the data stream of the medical scan received prior to completion of capturing the medical scan, wherein the artifact detection data indicates at least one artifact detected in the medical scan prior to the completion of capturing the medical scan; and
transmit, via a transmitter, a notification to a client device for display via a display device, wherein the notification indicates the at least one artifact.

2. The medical scan artifact detection system of claim 1 , wherein the medical scan corresponds to a magnetic resonance imaging (MRI) scan.

3. The medical scan artifact detection system of claim 1 , wherein the artifact detection function is further performed on image data of the medical scan, and wherein the image data is generated by performing at least one Fourier transform on the raw signal data of the medical scan.

4. The medical scan artifact detection system of claim 1 , wherein the artifact detection function is performed a plurality of times upon portions of the raw signal data received prior to each of the plurality of times, wherein the at least one artifact is detected in performing the artifact detection function one of the plurality of times, and wherein no artifact is detected in performing of the artifact detection function at least one other one of the plurality of times prior to the one of the plurality of times.

5. The medical scan artifact detection system of claim 1 , wherein a Fourier transform is performed on the raw signal data to produce image data, and wherein the Fourier transform is performed after the artifact detection function is performed on the raw signal data.

6. The medical scan artifact detection system of claim 5 , wherein the operational instructions, when executed by the at least one processor, further cause the medical scan artifact detection system to:
generate artifact location data by determining at least one location of the at least one artifact in the image data based on the artifact detection data, wherein the image data and the artifact location data is transmitted to the client device, and wherein display of the artifact location data is superimposed upon the image data indicate the at least one location of the at least one artifact.

7. The medical scan artifact detection system of claim 6 , wherein the operational instructions, when executed by the at least one processor, further cause the medical scan artifact detection system to:
receive a response transmission from the client device in response to the notification, wherein the response transmission is generated based on user input to an interactive interface displayed on the client device, and wherein the user input is entered by a user in response to a prompt displayed by the interactive interface to indicate whether the at least one artifact was detected correctly; and
regenerate the artifact detection data to remove the at least one artifact in response to the response transmission indicating the at least one artifact was detected incorrectly.

8. The medical scan artifact detection system of claim 4 , wherein the artifact detection function is performed on the data stream in response to each of a plurality of new data segments of the data stream being received to generate the artifact detection data.

9. The medical scan artifact detection system of claim 8 , wherein the operational instructions, when executed by the at least one processor, further cause the medical scan artifact detection system to:
generate an interrupt instruction for transmission to the medical imaging machine in response to the artifact detection data indicating the at least one artifact before capturing of the medical scan is complete, wherein the medical imaging machine foregoes completion of the capturing of the medical scan in response to receiving the interrupt instruction.

10. The medical scan artifact detection system of claim 8 , wherein the medical scan is captured by a medical imaging machine in accordance with a plurality of scan parameters, and wherein the operational instructions, when executed by the at least one processor, further cause the medical scan artifact detection system to:
generate updated scan parameters in response to the artifact detection data indicating the at least one artifact before capturing of the medical scan is complete; and
generate an instruction for transmission to the medical imaging machine that indicates the updated scan parameters, wherein a remainder of the capturing of the medical scan is performed by the medical imaging machine in accordance with the updated scan parameters.

11. The medical scan artifact detection system of claim 1 , wherein the operational instructions, when executed by the at least one processor, further cause the medical scan artifact detection system to:
generate artifact cause data based on the artifact detection data, wherein the artifact cause data indicates at least one problem during capturing of the medical scan that caused the artifact detection data, and wherein the notification indicates the artifact cause data.

12. The medical scan artifact detection system of claim 11 , wherein the at least one problem corresponds to at least one patient movement made by the patient that caused the at least one artifact.

13. The medical scan artifact detection system of claim 12 , wherein generating the artifact cause data includes selecting one of a plurality of patient movement types that corresponds to the at least one patient movement based on the artifact detection data, and wherein the plurality of patient movement types correspond to a plurality of body parts capable of motion and to a plurality of motion types.

14. The medical scan artifact detection system of claim 12 , wherein the notification includes a patient instruction to refrain from making the at least one patient movement in a recapturing of the medical scan.

15. The medical scan artifact detection system of claim 11 , wherein the medical scan is captured by a medical imaging machine in accordance with a plurality of scan parameters, and wherein the at least one problem corresponds to at least one incorrect scan parameter that caused the at least one artifact.

16. The medical scan artifact detection system of claim 15 , wherein the operational instructions, when executed by the at least one processor, further cause the medical scan artifact detection system to:
generate correct parameter data to correct the at least one incorrect scan parameter that caused the at least one artifact;
wherein the medical scan of the patient is recaptured by the medical imaging machine in accordance with the correct parameter data.

17. The medical scan artifact detection system of claim 1 , wherein the operational instructions, when executed by the at least one processor, further cause the medical scan artifact detection system to:
receive training set of medical scans and corresponding artifact detection data for the training set of medical scans; and
generate a model by training on raw signal data of the training set of medical scans and the corresponding artifact detectio
