Abstract
A C-arm imaging device method, apparatus and system are provided. The apparatus and system includes a module for determining the positions of an imaging source and an imaging receptor and a local gravity vector to determine an imaging source focal point displacement. The apparatus and system may include a module for determining magnetic field distortion. Data obtained by the apparatus and system can be stored for use in subsequent interpolation of imaging source focal point displacement for the C-arm imaging device.
