Abstract

Systems and methods are provided to facilitate orientation of a plane with respect to a three-dimensional representation. A device is presented utilizing at least one of an accelerometer, gyroscope, or combination thereof, enabling determination of a current position and/or orientation of the device. Outputs from the accelerometer, gyroscope, etc., are captured and orientation of a plane displayed with regard to the three-dimensional representation is accordingly adjusted to correspond with the position of the device. Imaging information relating to the three-dimensional representation and the plane can be captured facilitating analysis of the respective slice of the three-dimensional representation associated with the plane.
