Diffraction tomography - Wikipedia Diffraction tomography is an inverse scattering technique used to find the shape of a scattering object by illuminating it with probing waves and recording the reflections It is based on the diffraction slice theorem and assumes that the scatterer is weak
Diffraction Tomography - an overview | ScienceDirect Topics Diffraction is related to spreading of waves upon interaction with an object in the medium Diffraction tomography is an inverse scattering technique to reconstruct the object characteristics from the scattered field data measured at the receiver locations
[1507. 00466] The Theory of Diffraction Tomography - arXiv. org Here, we present a full literature review of diffraction tomography We derive the theory starting from the wave equation and discuss its validity with the focus on applications for refractive index tomography
Diffraction tomography with a deep image prior - PMC We present a tomographic imaging technique, termed Deep Prior Diffraction Tomography (DP-DT), to reconstruct the 3D refractive index (RI) of thick biological samples at high resolution from a sequence of low-resolution images collected under angularly varying illumination
Recent developments in X-ray diffraction scattering computed tomography . . . X-ray diffraction scattering computed tomography (XDS-CT) methods are a non-destructive class of chemical imaging techniques that have the capacity to provide reconstructions of sample cross-sections with spatially resolved chemical information
(PDF) The Theory of Diffraction Tomography - ResearchGate Diffraction tomography with the Rytov approximation resolves this issue The explicit incorporation of the wave nature of light results in an enhanced reconstruction of the object's refractive
Diffraction Tomography, Fourier Reconstruction, and Full Waveform . . . Diffraction tomography (DT) is a technique for reconstructing the scattering potential of an object from measurements of waves scattered by that object DT can be understood as an alternative to, or extension of, classical computerized tomography
CHAPTER 1 INTRODUCTION - Purdue University diffraction tomography uses diffracting energy sources to illuminate the object and then generates a cross sectional image of the object Since ultrasound and microwaves diffract and refract as they pass through most objects they require more sophisticated algorithms then the ones used for x-ray tomography These
Geophysical Diffraction Tomography: Theory Implementation and Results Geophysical diffraction tomography (GDT) is a high resolution technique for quantitative subsurface imaging The method is based on data derived from the propagation of scalar waves from an array of source positions to an array of receivers Images of spatial variations in
