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 a device used during a medical procedure, the method comprising:
identifying a medical instrument during the medical procedure; obtaining one or more customized configuration parameters for adaptively configuring the device during the medical procedure, where the customized configuration parameters are selected based on the identity of the medical instrument; and configuring the device according to the customized configuration parameters.

2 . The method according to claim 1 wherein the medical instrument is automatically identified.

3 . The method according to claim 2 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.

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

5 . The method according to claim 3 wherein the medical instrument is identified based on image analysis employing a known shape of the medical instrument.

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

7 . The method according to any one of claims 1 to 6 wherein identifying the medical instrument comprises identifying the type of the medical instrument.

8 . The method according to any one of claims 1 to 6 wherein identifying the medical instrument comprises uniquely identifying the medical instrument.

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

10 . The method according to claim 8 wherein uniquely identified medical instrument associated is associated with one or more regions of use.

11 . The method according to any one of claims 1 to 10 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.

12 . The method according to any one of claims 1 to 10 further comprising:
receiving input identifying the medical procedure;
wherein the customized configuration parameters are further associated with the medical procedure.

13 . The method according to any one of claims 1 to 12 further comprising:
determining a current stage of the medical procedure;
wherein the customized configuration parameters are further associated with the current stage of the medical procedure.

14 . The method according to any one of claims 1 to 13 wherein the customized configuration parameters are obtained from a data storage device comprising customized configuration parameters for adaptively configuring a plurality of devices during the medical procedure, the method further comprising:
identifying one or more additional medical instruments employed concurrently during the medical procedure;
wherein the one or more customized configuration parameters are selected based on the identity of identified medical instruments.

15 . The method according to claim 14 wherein the customized configuration parameters stored in the data storage device are ranked based on the identity of different medical instruments, and wherein the customized configuration parameters are obtained for the identified instrument having the highest ranking.

16 . The method according to any one of claims 1 to 15 wherein the device is an auxiliary device.

17 . The method according to any one of claims 1 to 16 wherein the device is an illumination device.

18 . The method according to any one of claims 1 to 16 wherein the device is computer hardware for generating a user interface on a display.

19 . The method according to any one of claims 1 to 16 wherein the device is a robotic positioning device.

20 . The method according to any one of claims 1 to 16 wherein the device is an imaging device.

21 . The method according to claim 20 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.

22 . The method according to claim 20 wherein the imaging device is a multimodal imaging device, and wherein the customized configuration parameters comprise a selection of an imaging modality.

23 . The method according to any one of claims 1 to 22 wherein the medical procedure is a surgical procedure.

24 . A system for adaptively and intraoperatively configuring a device used during a medical procedure, comprising:
a data storage device comprising customized configuration parameters for adaptively configuring one or more devices during the medical procedure; a control and processing system interfaced with the device and the data storage device, said control and processing system comprising one or more processors and memory coupled to said one or more processors, said memory storing instructions, which, when executed by said one or more processors, causes said one or more processors to perform operations comprising: identifying a medical instrument during the medical procedure; obtaining, from the data storage device, one or more customized configuration parameters for adaptively configuring the device during the medical procedure, where the customized configuration parameters are customized based on the identity of the medical instrument; and configuring the device according to the customized configuration parameters.

25 . A computer implemented method of adaptively configuring a device used during a medical procedure, the method comprising:
obtaining one or more images of a region of interest associated with the medical procedure; processing the one or more images to identify a context measure associated with the current state of the medical procedure; obtaining one or more customized configuration parameters for adaptively configuring the device during the medical procedure, where the customized configuration parameters are customized based on the context measure; and configuring the device according to the customized configuration parameters.

26 . The method according to claim 25 wherein the context measure is associated with a current phase of the medical procedure.

27 . The method according to claim 25 wherein the context measure is associated with the type of medical procedure.

28 . The method according to claim 25 wherein the context measure is associated with the presence of one or more tissue types within the region of interest.

29 . The method according to claim 25 wherein the context measure is associated with the presence of one or more fluids within the region of interest.

30 . The method according to claim 25 wherein one of the one or more fluids is a biological fluid.

31 . The method according to claim 25 wherein the biological fluid is blood.

32 . The method according to claim 25 wherein the context measure is associated with the presence of one or more med
