Spatial Anchoring

Principle: Anatomical positions can be assigned spatial coordinates.

Objective: To define the exact location of structures in 2D or 3D space for simulation and mapping.

Method: Coordinate Geometry

introduction

Just like Anatomical Planes & Landmark Systems

Sagittal Plane: divides left/right

Coronal Plane: divides front/back

Transverse Plane: divides top/bottom

Used to describe positions like: Stomach is inferior to diaphragm, anterior to spine, and left of midline"

We use

X-axis: Patient's Left (+) to Right (−)

Y-axis: Posterior (+) to Anterior (−)

Z-axis: Foot (+) to Head (−)
