1. A method for converting imaging data in polar format from a medical imaging device to Cartesian format, the method comprising:
- providing a medical imaging device configured and arranged for insertion of a probe of the medical imaging device into a patient;
generating imaging data in polar format by the medical imaging device, wherein the generated polar imaging data comprises a single distance Ri and a single angle θ
, for each of at least one physical object from a centerpoint of the imaging data; and
converting the generated polar imaging data into Cartesian format, wherein the conversion of the polar imaging data into Cartesian format, being performed on a computer, compriseswrapping the polar imaging data around a cone; and
reducing the height of the cone to zero.

Abstract
The improved system and method converts medical imaging data in R-θ or polar format to a Cartesian format that is readily recognizable to the human eye. The system and method texturize or wrap the R-θ imaging data around an object, which is preferably a cone. The height of the cone is zero, or reduced to zero, to create the Cartesian format. To texturize or wrap the R-θ imaging data around the cone, the preferred embodiment uses a commercially available graphics processing unit and software.
