Abstract

A workflow assistance system for image guided surgical procedures includes an interventional imaging system. The interventional imaging system operates to move relative to a patient and to acquire interventional images during a surgical procedure. A surveillance system is arranged about a surgical suite and produces surveillance data. A workflow controller processes the surveillance data to identify locations of clinicians, the patient, the interventional imaging system, and medical equipment within the surgical suite and provide operational commands to the interventional imaging system based upon the surveillance data.

First claim

The invention claimed is:

1. A workflow assistance system for image guided surgical procedures, comprising:
an interventional imaging system that operates to move relative to a patient and to acquire interventional images during a surgical procedure;
a surveillance system arranged about a surgical suite, the surveillance system producing surveillance data;
a workflow controller that processes the surveillance data to identify and locate surveillance subjects, the surveillance subjects comprising personnel, the patient, the interventional imaging system, and medical equipment, within the surgical suite based upon the surveillance data and provide operational commands to the interventional imaging system based upon analysis of the surveillance data;
wherein the surveillance system comprises a plurality of cameras and the surveillance data comprises image data from the plurality of cameras; and
wherein the workflow controller further receives static configuration data regarding the surgical suite, medical equipment, interventional imaging system or personnel and processes the surveillance data and the static configuration data to identify interactions between two or more surveillance subjects.

2. The workflow assistance system of claim 1 , wherein the operational commands to the interventional imaging system are movement commands to avoid collisions between the interventional imaging system and the patient, personnel, and medical equipment in the surgical suite.

3. The workflow assistance system of claim 1 , wherein the plurality of cameras comprises at least one pan-tilt-zoom camera, a depth camera, or a thermal camera.

4. The workflow assistance system of claim 1 , wherein the surveillance system further comprises a plurality of microphones and the surveillance data comprises audio data.

5. The workflow assistance system of claim 1 , wherein the workflow controller identifies locations and actions of the interventional imaging system and the personnel from the image data.

6. The workflow assistance system of claim 5 wherein the workflow controller comprises a learning engine that processes surveillance data from previous surgical procedures to interpret the surveillance data acquired during the surgical procedure.

7. The workflow assistance system of claim 1 , wherein the workflow controller identifies locations and actions of the interventional imaging system and clinicians from the surveillance data and identifies surgical procedure events from the identified locations and actions.

8. The workflow assistance system of claim 7 , further comprising a link to a hospital information system and the workflow controller automatedly records a surgical event log of the identified surgical procedure events and identified actions.

9. The workflow assistance system of claim 8 , wherein the hospital information system predicts a surgical procedure duration from the surgical event log.

10. The workflow assistance system of claim 9 , wherein the hospital information system adjusts a schedule of use of the surgical suite based upon the predicted surgical procedure duration.

11. The workflow assistance system of claim 7 , wherein the workflow controller obtains at least one procedural guideline from a hospital information system and compares the procedural guideline to the identified locations and actions of the clinicians and the identified surgical procedure events to evaluate the surgical procedure and create clinician guidance.

12. The workflow assistance system of claim 1 , wherein the surveillance system further comprises at least one wearable device associated with a clinician.

13. The workflow assistance system of claim 12 , wherein the wearable device is a dose meter and the workflow controller obtains radiation level data of the interventional imaging system, calculates a radiation dose received by the clinician, and produces guidance to the clinician regarding dose mitigation.

14. A workflow assistance system for image guided surgical procedures, comprising:
an interventional imaging system that operates to move relative to a patient and to acquire interventional images during a surgical procedure;
a surveillance system arranged about a surgical suite, the surveillance system producing surveillance data;
a workflow controller that processes the surveillance data to identify and locate surveillance subjects, the surveillance subjects comprising personnel, the patient, the interventional imaging system, and medical equipment, within the surgical suite based upon the surveillance data and provide operational commands to the interventional imaging system based upon analysis of the surveillance data;
wherein the surveillance system comprises a plurality of cameras and the surveillance data comprises image data from the plurality of cameras; and
wherein the workflow controller identifies locations and actions of the interventional imaging system and the personnel from the image data.

15. A workflow assistance system for image guided surgical procedures, comprising:
an interventional imaging system that operates to move relative to a patient and to acquire interventional images during a surgical procedure;
a surveillance system arranged about a surgical suite, the surveillance system producing surveillance data;
a workflow controller that processes the surveillance data to identify and locate surveillance subjects, the surveillance subjects comprising personnel, the patient, the interventional imaging system, and medical equipment, within the surgical suite based upon the surveillance data and provide operational commands to the interventional imaging system based upon analysis of the surveillance data;
wherein the surveillance system comprises a plurality of cameras and the surveillance data comprises image data from the plurality of cameras; and
wherein the workflow controller identifies locations and actions of the interventional imaging system and clinicians from the surveillance data and identifies surgical procedure events from the identified locations and actions.
