Isotropic Resolution(各向同性分辨率)研究综述
Isotropic Resolution 各向同性分辨率 - In this paper we utilize a compressive imaging strategy coupled with a context-aware image prior to improve Raman imaging speed by 5- to 10-fold compared to classic point-scanning Raman imaging, while maintaining the traditional benefits of point scanning imaging, such as isotropic resolution and confocality. [1] The benefits of 3D MRI, including general advantages, such as decreased acquisition time, isotropic resolution, and increased image quality, are not only inherently useful for tumor imaging, but they also contribute to the feasibility of more specialized tumor-imaging techniques, such as whole-body MRI, and are reviewed here. [2] Anatomic and diffusion images were rendered with isotropic resolutions of 50 μm and 200 μm, respectively. [3] The roots were imaged with micro-CT scanning at an isotropic resolution of 14 μm before and after root canal preparation, and the cross-sectional images generated were assessed to detect microcracks. [4] Preoperative CT images with an isotropic resolution of , and were acquired. [5] Here, we present an extension to our previously published structural ultrahigh resolution T 1 -weighted magnetic resonance imaging (MRI) dataset with an isotropic resolution of 250 µm, consisting of multiple additional ultrahigh resolution contrasts. [6] MicroCT is the only technique that combines a high spatial resolution (down to ∼1 µm) with the production of a true 3D organ reconstruction, with cubic voxels and isotropic resolution. [7] As cellular structures can be oriented in any direction, it is of great benefit if the microscope exhibits an isotropic resolution. [8] All these techniques suffer from anisotropic resolution and limited penetration depth. [9] We demonstrate the performance of our method by imaging phantoms and live cultures of fibroblast, cancer, and macrophage cells to achieve 59 dB sensitivity with isotropic resolution down to 1 μm, and displacement sensitivity down to 0. [10] However, due to non-isotropic resolution of the technique along the axial scanning, one may want to combine different views of the object and add deconvolution to the process in order to achieve higher resolution. [11] Ratlas-LH was produced with an isotropic resolution of 0. [12] Experiments on a CBCT C-arm validated many intuitive aspects of 3D spatial resolution and quantified the extent to which a CBCT system may be considered to have isotropic resolution. [13] Imaging with anisotropic resolution and/or reduced brain coverage has significant shortcomings including reduced registration accuracy and increased deviation in brain feature detection. [14] After the obturation of root canals with BioRoot RCS and one HyFlex EDM size 40 gutta-percha point, plastic models were scanned using micro-computed tomography scanner (µCT) SkyScan 1272 at isotropic resolution of 10 µm. [15] For vessel wall imaging (VWI), a high-resolution compressed-sensing black-blood 3D T1-weighted fast (turbo) spin echo sequence (T1 CS-SPACE prototype) was applied post gadolinium with an isotropic resolution of 0. [16] However, it is challenged by the small target region, anisotropic resolution of clinical CT images, and the low contrast between the target region and surrounding soft tissues. [17] 3D FLASH with an isotropic resolution of 150 µm and 3D spin-echo DTI at 600 µm were performed. [18] The cardiac structure was assessed through 2D and 3D T 1w images with isotropic resolutions of 150 µm. [19] 4 mm (7 T) isotropic resolution, respectively. [20] Considering that DBT volume has an anisotropic resolution, we proposed a novel 3D context-aware convolutional neural network (CNN) to reduce FPs, which consists of a 2D intra-slices feature extraction branch and a 3D inter-slice features fusion branch. [21] Each tooth was scanned using micro-computed tomography (SkyScan 1272; Bruker) at an isotropic resolution of 6 μm from which the percent of material removed was calculated. [22] Influenced by imaging method, DBT has the characteristic of anisotropic resolution, in which the resolution of intra-slice and inter-slice is quite different. [23] We show that cells can be directly grown on BIO-133 substrates without the need for surface passivation and use this capability to perform extended time-lapse volumetric imaging of cellular dynamics 1) at isotropic resolution using dual-view light-sheet microscopy, and 2) at super-resolution using instant structured illumination microscopy. [24] We combine SNR‐efficient acquisition and model‐based reconstruction strategies with newly available hardware instrumentation to achieve distortion‐free in vivo diffusion MRI of the brain at submillimeter‐isotropic resolution with high fidelity and sensitivity on a clinical 3T scanner. [25] A musculoskeletal model of the magpie hindlimb was developed using μCT scans (isotropic resolution of 18. [26] It is still limited by an anisotropic resolution and inhomogeneous labeling density. [27] Correcting for individual transducer responses, we demonstrate significant improvement in isotropic resolution, which further enhances the clinical potential of array-based handheld transducers. [28] Results The template creation takes advantage of high-resolution anatomical and diffusion-weighted images obtained at an isotropic resolution of 150 μm and 600 μm respectively, covering ventricles and atria and providing information on the normal myocardial architecture. [29] We also address two important limitations in FRC that may be of more general interest: how to make FRC work with single images (within certain practical limits) and with three-dimensional images with highly anisotropic resolution. [30] 3 mm interpolated) isotropic resolution in the detection of intracranial atherosclerosis. [31] To provide nonrigid respiratory motion‐corrected DCE‐MRI images with isotropic resolution of 1. [32] Furthermore, we demonstrate depth-resolved imaging of multilayer samples with an isotropic resolution in the μm range over a depth range that extends well beyond the depth-of-focus given by the numerical aperture of the imaging system. [33] Cryo-electron tomography maps often exhibit considerable noise and anisotropic resolution, due to the low-dose requirements and the missing wedge in Fourier space. [34] We have shown that at 7 T a 3D NMR image can be obtained with isotropic resolution of 50 μm/pxl within 10 min and 25 μm/pxl within 4 h. [35] The effects of such anisotropic resolution are often simplified or neglected in subgrid model formulation. [36] Starting as a pure head scanner, modern CT systems are now able to perform whole-body examinations within a couple of seconds in isotropic resolution, single-rotation whole-organ perfusion, and temporal resolution to fulfill the needs of cardiac CT. [37] HYDI was acquired at an isotropic resolution of 1. [38] Such anisotropic resolution can obscure fine ultrastructural features. [39] We have recently developed micro-optical coherence tomography (μOCT) that generates depth-resolved tissue images at a high frame rate with an isotropic resolution of 1 μm. [40] DTI using a b value of 3000 and an isotropic resolution of 0. [41] Implementation of a custom 2D isotropic filter improved CNR ~50-60% for both head and body protocols and provided more isotropic resolution and noise characteristics. [42] At an isotropic resolution of 5. [43] While developing the image restoration methods, we also addressed two important limitations in FRC that are of more general interest: how to make FRC work with single images and with three-dimensional images with anisotropic resolution. [44] The specimens were scanned before and after canal filling at an isotropic resolution of 9. [45] The recent developments in X-Ray microtomography enable three-dimensional imaging at sub-micrometer and isotropic resolution with larger biological samples. [46] Preoperative and postoperative scans were obtained at the isotropic resolution of 13. [47] Cone-beam breast computed tomography (CT) provides true 3D breast images with isotropic resolution and high-contrast information, detecting calcifications as small as a few hundred microns and revealing subtle tissue differences.
