Patient motion image artifacts can be minimized and re-exposure avoided by selective removal of a sequence of basis images from cone beam computed tomography datasets: A case series

This case series describes a reconstruction method applied to a cone beam computed tomography (CBCT) projection dataset that uses selected basis projection images to improve diagnostic image quality for patients who moved during radiographic procedure. Reconstructed volumetric data from six patients at two institutions initially exhibited characteristic double contour images due to motion artifacts. For each case, the CBCT basis images from the entire projection dataset were displayed as a cine sequence, and patient movement was identified during the first or last 90-degrees of a full 3600 acquisition trajectory.
