Two-dimensional space or bi-dimensional space is a geometric setting in which two values (called parameters) are required to determine the position of an element (i.e., point). In Mathematics, it is commonly represented by the symbol ℝ2.
For a generalization of the concept, see dimension.
Techniques for the production and reproduction of 3D images have been refined in the last two decades, and awareness of the value of 3D imaging applied to medical education has increasingly been appreciated 1).
