Abstract:
Ultrasound's value in the neurosurgical operating room is maximized when fused with pre-operative images, The disclosed system enables real-time multimodal image fusion by estimating the ultrasound's pose with use of an image-based registration constrained by sensor measurements and pre-operative image data. Once the ultrasound data is collected and viewed, it can be used to update the pre-operative image, and make changes to the pre-operative plan. If a surgical navigation system is available for integration, the system has the capacity to produce a 3D ultrasound volume, probe-to-tracker calibration, as well as an optical-to-patient registration. This 3D ultrasound volume, and optical-to-patient registration can be updated with conventional deformable registration algorithms and tracked ultrasound data from the surgical navigation system. The system can also enable real-time image-guidance of tools visible under ultrasound by providing context from the registered pre-operative image when said tools are instrumented with sensors to help constrain their pose.

Claim (Index 19):
A system for visualizing ultrasound images in three-dimensional space during a medical procedure, comprising:\n a. an ultrasound probe; b. at least one sensor for measuring pose information from said ultrasound probe; and c. an intra-operative multi-modal display system for\n i. receiving pre-operative image data and pre-operative plan data to estimate a range of possible poses; \n ii. receiving ultrasound image data from said ultrasound probe; \n iii. estimating pose of the ultrasound probe by executing an image-registration algorithm constrained to the estimated range of possible poses; \n iv. receiving position data from the at least one sensor and in response refining the estimated pose of the ultrasound probe; and \n v. displaying the pre-operative image data with information from the ultrasound image data.
