Looking towards the future, despite its limitations, ST has the potential to address these problems in conjunction with “dynamics, multi-omics, and resolution”. Ultimately, the development of ST technology, improvement of algorithms, utilization of deep learning, and refinement of the analysis ...
Optimization of the in-line X-ray phase-contrast imaging setup considering edge-contrast enhancement and spatial resolution 来自 掌桥科研 喜欢 0 阅读量: 75 作者:QJ Jia,Y Chen,G Li,XM Jiang 摘要: Employing the approximation theory based on refraction and the definition of the total point-spread...
resolution determines the number of rows in the entire scan. Likewise, it will be appreciated how these principles may be applied to additional scanners such as the HDS6000, to LIDAR systems such as the system shown in FIG. 2 or to various other systems that collect position data in a ...

Spatial resolutionBackground: The purpose of this study was to analyze the correlation between spatial resolution and ball distortion rate of panoramic radiography and to elucidate the minimum criterion for ball distortion rate, which is very relevant to clinical readability. Methods: Horizontal and ...
This is mostly due the multiple Coulomb scattering (MCS) that the ions undergo in the imaged object. In this work, a novel technique to improve the spatial resolution in helium-beam radiography was developed. Increasing helium-beam energies were exploited in order to decrease the MCS, and ...
