Iterative Motion Compensated Reconstruction
Introduction: Motion during data acquisition can seriously degrade image quality. Motion compensated reconstruction can restore image quality if the motion is measured with suitable navigator signals. We present a new scheme for motion compensated reconstruction which can be applied to segmented Cartesian acquisitions (e.g. TSE, TFE). It can be combined with parallel imaging and is fast because...
متن کاملMotion-compensated Image Reconstruction with Alternating Minimization
Cardiac computed tomography (CT) is important for its use in diagnosing heart disease. Motion artifacts are a significant issue for cardiac CT image reconstruction. Motioncompensated image reconstruction (MCIR) has the potential to overcome the drawbacks of conventional gated reconstruction methods by exploiting all the measurement data and using motion information. However, MCIR methods are co...

متن کاملMotion Correction of SPEC Projection before Reconstruction
In Single Photon Emission Computed Tomography (SPECT), the data acquisition occurs over a relatively long time, typically in the range of 5-30 minutes. During this period, the patient must lie still to guarantee the image quality. Nevertheless, patient movement has frequently been reported in clinical applications. This movement causes misalignment of the projection frames, which degrades the r...
