Dynamic spatial reconstruction
WebThere is a need to improve dynamic PET to allow fine temporal sampling of 1-2 seconds. However, the reconstruction of these short-time frames from tomographic data is extremely challenging as the count level of each frame is very low and high noise presents in both spatial and temporal domains. WebDynamic Replacement (DR) technique is an extension of Dynamic Compaction to compressible soils (such as soft clays,silt, sabkha ...) where a large diameter columns …

WebOct 10, 2024 · Dynamic Magnetic Resonance Imaging (MRI) is a non-invasive imaging technique to monitor dynamic processes such as cardiac motion by acquiring data in a k - t space that contains both temporal and spatial information. However, the acquisition speed is limited due to both physical and physiological constraints. WebProposed hybrid-domain reconstruction using spatial nulling maps. ... Furthermore, with the fast convergency, the proposed method can be extended to potentially real-time 3D or dynamic imaging in the future. Second, the proposed method derives image-domain spatial nulling maps with explicit coil sensitivity information. Such image-domain coil ...
