  • Patent number: 8650005
    Abstract: A method may include displaying one or more interactive 2D images, each 2D image representing at least bony tissue cranio-facial features of a patient and each 2D image having one or more portions each associated with a corresponding portion of the patient's bony. The method may also include displaying a 3D image representing exterior soft-tissue cranio-facial features of the patient. The method may additionally include receiving input from a user regarding movement of a particular portion of the one or more portions of the 2D image. The method may further include redrawing the 3D image based at least on the movement of the particular portion of the 2D image to simulate response of the exterior soft-tissue cranio-facial features of the patient to movement of a portion of the patient's bony tissue corresponding to the particular portion of the 2D image.

  • Patent number: 8417004
    Abstract: In accordance with embodiments of the present disclosure, a method may include mapping an ellipse with its center at the origin of an xy-coordinate plane to a circle with its center at the origin of the xy-coordinate plane. The method may also include transforming a three-dimensional subject image including a curved profile in the xy-coordinate plane to an intermediate image based at least on the mapping of the ellipse to a base circle. The method may further include transforming the intermediate image to a transformed image having a linear profile by distorting each of one or more points of interest of the intermediate image based at least on a dimension of the circle and a coordinate of such point.

  • Patent number: 7978191
    Abstract: A system and method for modifying a curved cut plane of a 3D volume to locate objects or sections of interest within the 3D volume intersected by the cut plane. A cross-section of the 3D volume along an initially estimated curved cut plane is projected onto a flat viewing plane, and a panorama image of the cross-section is displayed to the user. If the initially estimated curved cut plane does not exactly intersect the object or section of interest, the user manipulates a user input device to modify the curve of the plane inward or outward in the 3D volume away from the projected plane. As the user manipulates the user input device, an affected portion of the curve is recalculated and a modified curved cut plane is reconstructed based on the recalculated curve for re-projecting a modified cross-section of the 3D volume in real time with the movement of the user input device.
