Spaces Involved

Referring again to over, this section describes in some detail the different spaces involved in . As a first step, the schematic can be separated into four regions, as follows:

• the left half represents objects in real physical world,
• the right half represents measurements of the geometry of physical objects,
• the top half represents the time of image acquisition and
• the bottom half represents the time of surgery.

• Physical space
• Model Space
• Scanner Space
• Surgical Space
