Abstract:
1. A method of creating a surface model of an anatomy, comprising: obtaining a first plurality of location points defining a first section of the anatomy, said first plurality of location points having a first mean center point from which a line of sight may be drawn to every location point of the first plurality of location points; generating a first three-dimensional surface model of the first section of the anatomy using the first plurality of location points; obtaining a second plurality of location points defining a second section of the anatomy, said second plurality of location points having a second mean center point from which a line of sight may be drawn to every location point of the second plurality of location points, wherein said second section of the anatomy includes at least an area of the anatomy that is not included within the first section of the anatomy, and wherein at least one location point of the second plurality of location points is not within a line of sight of the first mean center point; generating a second three-dimensional surface model of the second section of the anatomy using the second plurality of location points; and combining the first three-dimensional surface model with the second three-dimensional surface model to create a composite three-dimensional surface model for the first and second sections of the anatomy.
