Image Artifact Influence on Motion Compensated Tomographic Reconstruction in Cardiac C-arm CT
In C-arm CT, electrocardiogram (ECG)-gating of data from a single C-arm rotation provides only a few projections per heart phase for image reconstruction. This view starvation leads to prominent streak artifacts and a poor signal to noise ratio. Motion compensation techniques allow for the use of all acquired data for image reconstruction. Cardiac motion can be estimated by deformable 3-D/3-D r...
متن کاملArtifact reduction techniques in Cone Beam Computed Tomography (CBCT) imaging modality
Introduction: Cone beam computed tomography (CBCT) was introduced and became more common based on its low cost, fast image procedure rate and low radiation dose compared to CT. This imaging modality improved diagnostic and treatment-planning procedures by providing three-dimensional information with greatly reduced level of radiation dose compared to 2D dental imaging modalitie...
متن کاملCatheter Artifact Reduction (CAR) in Dynamic Cardiac Chamber Imaging with Interventional C-arm CT
A C-arm CT system offers the possibility to acquire 2-D high-resolution X-ray images of the patient from different views. These projections can be used for 3-D imaging. Anatomical three-dimensional imaging holds great potential to improve cardiac interventions. However, the image acquisition using a C-arm CT system takes several seconds. A standard FDK reconstruction using all acquired projecti...
متن کاملCoping with real world data: Artifact reduction and denoising for motion-compensated cardiac C-arm CT.
PURPOSE Detailed analysis of cardiac motion would be helpful for supporting clinical workflow in the interventional suite. With an angiographic C-arm system, multiple heart phases can be reconstructed using electrocardiogram gating. However, the resulting angular undersampling is highly detrimental to the quality of the reconstructed images, especially in nonideal intraprocedural imaging condit...
متن کاملMetal artifact reduction in CT using fusion based prior image.
PURPOSE In computed tomography, metallic objects in the scanning field create the so-called metal artifacts in the reconstructed images. Interpolation-based methods for metal artifact reduction (MAR) replace the metal-corrupted projection data with surrogate data obtained from interpolation using the surrounding uncorrupted sinogram information. Prior-based MAR methods further improve interpola...
