REGISTRATION DEGRADATION CORRECTION FOR SURGICAL NAVIGATION PROCEDURES
New and innovative systems and methods for registration degradation correction for surgical procedures are disclosed. An example system includes a surgical marking pen including a first trackable target and a registration plate including a second trackable target. The system also includes a navigation camera and a processor configured to perform a pen registration that determines a transformation between a tip of the surgical marking pen and the first trackable target when the tip of the surgical marking pen is placed on the registration plate. The pen registration enables the processor to record virtual marks at locations of the pen tip that correspond to physical marks drawn by the pen. Locations of the virtual marks are later compared to images of the physical marks to correct any registration degradation by moving a surgical camera or robotic arm connected to the surgical camera.
Medical imaging with functional architecture tracking
A pre-event connectome of a subject brain is accessed, the pre-event connectome defining i) first functional nodes in the subject brain and ii) first edges that represent connections between the first functional nodes before the subject has undergone an event. A post-event connectome of the subject brain is accessed, the post-event connectome defining i) second functional nodes in the subject brain and ii) second edges that represent connections between the second functional nodes after the subject has undergone the event. A connectome-difference map data is generated that records the difference between the pre-event connectome and the post-event connectome. An action is taken based on the connectome-difference map data.
