For this purpose, we design a cross-frame adaptive enhancement network to achieve temporal super-resolution, which effectively utilizes input frame features to generate missing frame features and employs cross-frame deformable attention mechanism to enrich the expression of missing frame features, ...
Temporal Super-Resolution forFast T1 Mapping 来自 Springer 喜欢 0 阅读量: 3 作者:X Zhao,J Lyu,F Wang,C Wang,J Qin 摘要: Cardiac T1 mapping can provide important biomarkers for many cardiovascular diseases. However, the acquisition time of the T1 mapping sequence is relatively long, which ...
For the fMRI recordings, we used the same two sets of ads from the 2012 and 2013 SuperBowls. All MRI data were acquired on a Siemens Magnetom Trio 3T scanner. A high-resolution T1 structural scan (3D MPRAGE, TI=850 ms, flip angle=9°, 1 mm isotropic resolution) was acquired bef...
As Mn2+ is an excellent T1-shortening contrast agent for MRI and can also enter viable myocardial cells via voltage gated calcium channels, manganese-enhanced MRI (MEMRI) has been implemented in this study to estimate the dynamic uptake of manganese in a murine MI model and to asse...
Collecting all data in a quiescent time window has limited T1 mapping to a reduced number of k-space lines, often with parallel imaging. These compromises lead to low spatial resolution and/or low signal-to-noise (SNR) images. This work explores the initial feasibility of accelerating the ...
Methods Myocardial T1 mapping was performed in two cohorts - (1) "amyloid +" subjects, defined by biopsy-proven systemic amyloid with associated remodeling suggestive of cardiac involvement (left ventricular [LV] hypertrophy and/or atrial dilation); (2) normative controls without risk factors for ...
Recent experiments suggest that T1 relaxation in the rotating frame (T(1ρ)) is sensitive to metabolism and can detect localized activity-dependent changes in the human visual cortex. Current functional magnetic resonance imaging (fMRI) methods have poor temporal resolution due to delays in the ...
Furthermore, the one arc-second shuttle radar topography mission (SRTM) digital elevation model (DEM) with a resolution of 30 m was used to remove the topographic phase and geocoding. 3. Method As shown in Figure 2, the processing flow of multi-temporal InSAR mainly consists of four steps:...
Firstly, we collect two datasets for point cloud super-resolution, encompassing CARLA32-128in simulated environments and Ruby32-128 in real-world scenarios. Secondly, we propose a novel temporal and spatial feature-enhanced point cloud super-resolution model. This model leverages temporal feature ...
