Image Quality Assessment of Step&Shoot Overlap Reconstruction (SSOR) for Cardiac Computed Tomography (CT)

Year: 2011

Type: article

Abstract: BACKGROUND: Step&Shoot cardiac computed tomography (CT) provides the benefit of significant reduction in radiation dose compared to helical cardiac CT acquisitions. We think that a difference occurs in image quality by presence of overlap reconstruction (fractionated sentence, attempted to clarify). PURPOSE: We studied the utility of Step&Shoot overlap reconstruction (SSOR). METHODS: We evaluated image quality of SSOR by comparing z-axis spatial resolution on various s in scanners that SSOR is possible and for those that are impossible. RESULTS: SSOR indicated better z-axis spatial resolution and less variation over the field of view (FOV) (in z & x-y directions) as compared with Step&Shoot without overlap reconstruction (SS). In addition, SS showed inadequate image reproducibility due to aliasing error in z-direction (lack of sampling interval). CONCLUSIONS: SSOR would contribute to improvement of the image quality of Step&Shoot cardiac CT.
