Abstract

Systems and methods are provided in some embodiments for recording, storage and replay of captured video from a surgical navigation system, a fluoroscopic imaging system, or an integrated fluoroscopy and navigation system. In some embodiments, full resolution video data is captured in an acquisition buffer and is available for replay and storage.

Claims

1. A method for recording images obtained by a fluoroscopic imaging and navigation apparatus, the method comprising:

receiving a plurality of digital images from the fluoroscopic imaging and navigation apparatus;

capturing the plurality of digital images from the fluoroscopic imaging and navigation apparatus; and

buffering the captured plurality of digital images.

2. The method of claim 1, further comprising receiving a triggering event that is one or more of an x-ray on event, a tracking on event, an interframe variation event, or a user defined trigger event.

3. The method of claim 1, wherein the step of capturing the plurality of digital images is acquired at one or more of a full frame rate, a lower frame rate, or a navigation system sample rate.

4. The method of claim 1, wherein the step of buffering the captured plurality of digital images further comprises:

continuously storing the captured plurality of digital images in an acquisition buffer having a predetermined size on a recording medium; and

,

replacing the captured plurality of digital images in the acquisition buffer with a next captured plurality of digital images in the acquisition buffer when a total plurality of digital images exceeds the size of the recording medium.

5. The method of claim 4, further comprising:

selecting a portion of the stored plurality of digital images in the acquisition buffer; and

,

preserving the selected portion of the stored plurality of digital images in the acquisition buffer.

6. The computerized method of claim 5, wherein the step of preserving the selected portion of the stored plurality of digital images in the acquisition buffer further comprises:

reserving the selected portion of the stored plurality of digital images in the acquisition buffer from being overwritten;

or,

transferring the selected portion of the stored plurality of digital images in the acquisition buffer to a predetermined location such as a hard drive, a flash memory, a data repository, or an external data storage device.

7. The method of claim 5, wherein the step of selecting a portion of the stored plurality of digital images in the acquisition buffer further comprises:

selecting the portion of the stored plurality of digital images in the acquisition buffer based on one or a combination of the triggering event, a user selection, or an inference model;

wherein the selected portion can be all of the plurality of digital images in the acquisition buffer, or a portion that is less than all of the plurality of digital images in the acquisition buffer.

8. The method of claim 6, wherein the step of transferring the selected portion of the stored plurality of digital images in the acquisition buffer to a predetermined location further comprises:

compressing the selected portion of the stored plurality of digital images in the acquisition buffer before transferring.

9. A system for recording of images obtained by a fluoroscopic imaging and navigation apparatus comprising:

a processor;

a storage device coupled to the processor; and

,

software means operative on the processor for;

receiving a plurality of digital images from the fluoroscopic imaging and navigation apparatus;

capturing the plurality of digital images from the fluoroscopic imaging and navigation apparatus; and

buffering the captured plurality of digital images from the imaging and navigation apparatus.

10. The system of claim 9, further comprising receiving a triggering event that is one or more of an x-ray on event, a tracking on event, an interframe variation event, or a user defined trigger event.

11. The system of claim 9, wherein the captured plurality of digital images is acquired at one or more of a full frame rate, a lower frame rate, or a navigation system sample rate.

12. The system of claim 9, the system further comprising:

an acquisition buffer having a predetermined size on a recording medium for continuously storing the captured plurality of digital images; and

,

replacing the captured plurality of digital images in the acquisition buffer with a next captured plurality of digital images in the acquisition buffer when a total plurality of digital images exceeds the size of the recording medium.

13. The system of claim 9, wherein the software means operative on the processor performing the additional function of:

selecting a portion of the stored plurality of digital images in the acquisition buffer; and

,

preserving the selected portion of the stored plurality of digital images in the acquisition buffer.

14. The system of claim 13, wherein preserving the selected portion of the stored plurality of digital images in the acquisition buffer further comprises:

reserving the selected portion of the stored plurality of digital images in the acquisition buffer from being overwritten;

or,

transferring the selected portion of the stored plurality of digital images in the acquisition buffer to a predetermined location such as a hard drive, a flash memory, a data repository, or an external data storage device.

15. The system of claim 13, wherein selecting a portion of the stored plurality of digital images in the acquisition buffer further comprises:

selecting the portion of the stored plurality of digital images in the acquisition buffer based on one or a combination of the triggering event, a user selection, or an inference model;

wherein the selected portion can be all of the plurality of digital images in the acquisition buffer, or a portion that is less than all of the plurality of digital images in the acquisition buffer.

16. The system of claim 14, wherein transferring the selected portion of the stored plurality of digital images in the acquisition buffer to a predetermined location further comprises:

compressing the selected portion of the stored plurality of digital images in the acquisition buffer before transferring.

17. The system of claim 12, wherein the recording medium is any one of a storage device coupled to the processor, a random access memory (RAM), a flash drive, a hard drive, a read only memory device, or a non-volatile memory device.

18. A computer-accessible medium having executable instructions for recording of images obtained by a fluoroscopic imaging and navigation apparatus, the executable instructions capable of directing a processor to perform:

receiving a plurality of digital images from the fluoroscopic imaging apparatus;

capturing the plurality of digital images from the fluoroscopic imaging apparatus;

buffering the captured plurality of digital images in an acquisition buffer having a predetermined size on a recording medium;

replacing the captured plurality of digital images in the acquisition buffer with a next captured plurality of digital images in the acquisition buffer when a total plurality of digital images exceeds the size of the recording medium;

wherein the captured plurality of digital images is acquired at one or more of a full frame rate, a lower frame rate, or at a navigation system sample rate.

19. The computer-accessible medium of claim 18, the processor further performing:

selecting a portion of the stored plurality of digital images in said acquisition buffer; and
