Real-time cephalometry for cranimaxillofacial surgery

A system for cephalometry for orthognathic and craniomaxillofacial surgery, comprising:

• a memory storing instructions;
• and
• at least one processor coupled to the memory and executing the instructions to perform a method comprising:
• transforming a set of cephalometric landmarks from a skeletal fragment in a first reference frame to a second reference frame based on a registration process that maps coordinates from the first reference frame to coordinates in the second reference frame;
• tracking movement, based on one or more signals from one or more sensors, during surgery, of one or more of the cephalometric landmarks in the set of cephalometric landmarks associated with a skeletal fragment with respect to one or more of the cephalometric landmarks in the set of cephalometric landmarks associated with a second skeletal portion in the second reference frame;
• calculating one or more cephalometry metrics, during surgery, based on the movement that is tracked;
• and
• providing updates of the one or more cephalometry metrics that were calculated.

A non-transitory computer-readable medium including instructions to perform a method for cephalometry for orthognathic and craniomaxillofacial surgery, the method comprising:

• transforming a set of cephalometric landmarks from a skeletal fragment in a first reference frame to a second reference frame based on a registration process that, maps coordinates from the first reference frame to coordinates in the second reference frame;
• tracking movement, based, on one or more signals from one or more sensors, during surgery, of one or more of the cephalometric landmarks in the set of cephalometric landmarks associated with a skeletal, fragment with respect to one or more of the cephalometric landmarks in the set of cephalometric landmarks associated with a second skeletal portion in the second reference frame;
• calculating one or more cephalometry metrics, during surgery, based on the movement that is tracked;
• and
• providing updates of the one or more cephalometry metrics that were calculated.
