Abstract

Systems and methods are provided in which devices that are employed during a medical procedure are adaptively configured during the medical procedure, based on input or feedback that is associated with the current state, phase or context of the medical procedure. In some example embodiments, the input is obtained via the identification of one or more medical instruments present within a region of interest, and this input may be employed to determine configuration parameters for configuring the device. In other example embodiments, the input may be based on the image-based detection of a measure associated with the phase or context of the medical procedure, and this input may be employed to adaptively control the device based on the inferred context or phase of the medical procedure. In other embodiments, images from one imaging modality may be employed to adaptively switch to another imaging modality.

First claim

Therefore what is claimed is:

1. A computer implemented method of adaptively and intraoperatively configuring an imaging device used during a medical procedure, the method comprising:
during the medical procedure, detecting, with a detection device, one or more signals or images associated with a plurality of medical instruments employed concurrently during the medical procedure;
processing the one or more signals or images to intraoperatively identify the medical instruments during the medical procedure;
performing one or more intraoperative diagnostic measurements, thereby obtaining intraoperative diagnostic data;
processing the intraoperative diagnostic data to determine the current phase of the medical procedure;
accessing configuration data from a data storage device, the configuration data associating customized configuration parameters for the imaging device with the identities of different medical instruments and with phases of a medical procedure, wherein the customized configuration parameters are selected and ranked based on the identities of different medical instruments;
processing the configuration data to determine, based on the medical instrument having the highest ranking and the current phase of the medical procedure, one or more customized configuration parameters for adaptively configuring the imaging device during the medical procedure; and
intraoperatively configuring the imaging device according to the customized configuration parameters;
wherein the imaging device is a separate device that is not connected to the medical instrument during the medical procedure.

2. The method according to claim 1 wherein the medical instrument is identified by:
detecting a signal from one or more fiducial markers associated with the medical instrument; and
processing the signal to identify the medical instrument.

3. The method according to claim 2 wherein the one or more fiducial markers are selected from the group consisting of passive markers, active markers, glyphs and RFID tags.

4. The method according to claim 2 wherein the medical instrument is identified based on image analysis employing a known shape of the medical instrument.

5. The method according to claim 1 wherein identifying one or more medical devices comprises receiving input from an operator, wherein the input from the operator identifies the medical instrument.

6. The method according to claim 1 wherein identifying the medical instrument comprises identifying the type of the medical instrument.

7. The method according to claim 1 wherein identifying the medical instrument comprises uniquely identifying the medical instrument.

8. The method according to claim 7 wherein uniquely identified medical instrument is associated with one or more operators.

9. The method according to claim 7 wherein uniquely identified medical instrument is associated with one or more regions of use.

10. The method according to claim 1 further comprising:
receiving input identifying one or more operators present during the medical procedure;
wherein the customized configuration parameters are further associated with the identity of the one or more operators.

11. The method according to claim 1 wherein the customized configuration parameters comprise one or more of colour balance, brightness, depth of field, magnification, field of view, working distance, and illumination conditions.

12. The method according to claim 1 wherein the imaging device is a multimodal imaging device, and wherein the customized configuration parameters comprise a selection of an imaging modality.

13. The method according to claim 1 wherein the medical procedure is a surgical procedure.
