System and method for sensory defect simulation
First Claim
1. A method for simulating a visual defect produced by a planned operation on a patient'"'"'s brain, the method comprising the steps of:
- a) producing a functional field map that relates locations in the patient'"'"'s field of view to regions in the patient'"'"'s brain;
b) designating regions in the patient'"'"'s brain that are affected by the planned operation;
c) producing a revised functional field map that indicates locations in the patient'"'"'s field of view that are affected by the regions designated in step b);
d) displaying a scene that substantially fills the field of view of a user; and
e) altering the displayed scene at locations therein determined by the locations indicated in step c).

Abstract
A visual defect simulation system receives a functional field map produced by an MRI system that relates locations in a patient'"'"'s brain to locations in the patient'"'"'s field of view. Planned medical operations are indicated at locations in the patient'"'"'s brain and any resulting vision loss is simulated with a revised functional field map. A scene is displayed and an impairment overlay is produced from the revised functional field map that blocks the scene at locations corresponding to simulated vision loss. The overlay is translated over the scene in response to viewer eye movements detected by a vision-tracking system to present a real-time simulation of the resulting vision loss.

8. A visual defect simulation system comprising:
-
a functional field map of a patient'"'"'s brain; a user input configured to receive parameters indicating a proposed process to be performed on the patient'"'"'s brain; a processor for receiving the parameters from the user input and the functional field map and being operable to predict at least one visual defect that will result from the proposed process; and a display coupled to the processor for displaying an image simulating the at least one visual defect. - View Dependent Claims (9, 10, 11, 12, 13, 14)
