Multiplanar reconstructions and three-dimensional imaging (computed rotational osteography) of complex fractures by using a C-arm system: Initial results

With use of a calibrated angiographic C-arm system and a postprocessing wor kstation, the authors acquired volume data sets from two-dimensional digita l projection images obtained during a C-arm rotation around the patient axi s. Multiplanar reconstruction and three-dimensional images of complex fract ures were reconstructed and compared with spiral computed tomographic studi es in a cadaveric pig study and in eight patients. Computed rotational oste ography provided high-resolution multiplanar reconstruction and three-dimen sional images of complex fractures.
