Radiologically navigated intra-operative spinal guidance system

A computer-implemented method, comprising:

• extracting, from real-time ultrasound data encoding 3D surface information of one or more bone structures located in a region of a patient, a first 3D surface representation of the one or more bone structures;
• extracting, from non-ultrasound imaging data including 3D surface anatomical information of the one or more bone structures in the region, a second 3D surface representation of the one or more bone structures;
• identifying, using a deep learning algorithm, one or more regions of interest (ROIs) from the first 3D surface representation to determine a spatial transformation for aligning the first 3D surface representation and the second 3D surface representation;
• and
• applying the spatial transformation to overlay the 3D surface anatomical information from the non-ultrasound imaging data on the 3D surface information from the real-time ultrasound data.

A system comprising:

• an ultrasound probe operable to insonify a region of a patient;
• a display device capable of providing real-time visual feedback during a surgical procedure;
• and
• a computer processor in communication with the ultrasound probe and the display device, the computer processor is configured to:
• extract, from real-time ultrasound data encoding 3D surface information of one or more bone structures located in a region of a patient, a first 3D surface representation of the one or more bone structures;
• extract, from non-ultrasound imaging data including 3D surface anatomical information of the one or more bone structures in the region, a second 3D surface representation of the one or more bone structures;
• identify, using a deep learning algorithm, one or more regions of interest (ROIs) from the first 3D surface representation to determine a spatial transformation for aligning the first 3D surface representation and the second 3D surface representation;
• and
• apply the spatial transformation to overlay the 3D surface anatomical information from the non-ultrasound imaging data on the 3D surface information from the real-time ultrasound data.
