20.A magnetic resonance imaging system comprising:a scanner configured to acquire a first MRI image and a second MRI image using different gradient fields; anda data processing apparatus configured to:receive the first MRI image and the second MRI image;estimate displacements of voxels between the ...
Zhu et al. [21] proposed end-to-end training of a deep multi-instance network to classify mammogram X-ray images without annotated labels and verified the robustness of the proposed deep network on the INbreast dataset. The successful application of deep learning in the diagnosis of various ...
Although they cannot be directly observed, astronomers can observe a black hole's surroundings, which can emit various types of radiation. Scroll through this gallery to see images of black holes throughout the universe, captured with the aid of radiation-detecting telescopes on Earth and in ...
However, these works are limited to specific fields. None of them can flexibly adapt to various combinations of resolution and modality, and perform CMS, SR, and CMSR with a single network. Moreover, alias frequencies are often treated carelessly in these works, leading to inferior detail-...
We present an analysis of a CME that was ejected off the west limb of the Sun on August 13, 1997. As observed by the SOHO telescopes, various features in the CME propagated outward with gradual acceleration so that at 29 solar radii, velocities of the features ranged between 260 and ...
of various sharp edges in AFM images of a perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) molecules on Ag(111) does not change with distance (Fig. 2c–f). This finding can be rationalized by the fact that the position of sharp edges is determined by the distance where the ...
and Doi at the University of Chicago widened systematic medical image analysis via machine learning for computer-aided diagnosis and reduction of physician labor in the 1980’s24. Since then, machine learning has been extending worldwide into various kinds of medical applications, such as digitized ...
Contrast evaluation of the polarimetric images of different targets in turbid medium: possible sources of systematic errors Subsurface polarimetric (differential polarization, degree of polarization or Mueller matrix) imaging of various targets in turbid media shows image contra...

Another advantage is that the effects of various imaging parameters related to the contrast of the image, such as X-ray irradiation time and irradiation dose, can be removed from the input image because the intensity of CT in Hounsfield units is normalized so that it linearly correlates with ...
The system is designed for pre-clinical studies and can capture image data from an extended field of view compared to the previous, experimental system. The contribution introduces concepts for the encoding of a larger field of view by means of additional magnetic fields, named focus-fields, and...
