Guidelines for assessment of bone microstructure in rodents using micro–computed tomography
Journal of Bone and Mineral Research, 2010 Use of high‐resolution micro–computed tomography (µCT) imaging to assess trabecular and cortical bone morphology has grown immensely. There are several commercially available µCT systems, each with different approaches to image acquisition, evaluation ...

Universal quantum data compression via gentle tomography [PDF]
Phys. Rev. A 73, 032336 (2006), 2004 Quantum state tomography--the practice of estimating a quantum state by performing measurements on it--is useful in a variety of contexts. We introduce "gentle tomography" as a version of tomography that preserves the measured quantum data. As an application of gentle tomography, we describe a simple polynomial-time method for universal source coding.

Quantum tomography with wavelet transform in Banach space on Homogeneous space [PDF]
Eeuopean Physical Journal B, 60, 193-201(2007), 2008 The intimate connection between the Banach space wavelet reconstruction method on homogeneous spaces with both singular and nonsingular vacuum vectors, and some of well known quantum tomographies, such as: Moyal-representation for a spin, discrete phase space tomography, tomography of a free particle, Homodyne tomography, phase space tomography and SU ...

Shadow process tomography of quantum channels [PDF]
Phys. Rev. A 107, 042403 (2023), 2021 Quantum process tomography is a critical capability for building quantum computers, enabling quantum networks, and understanding quantum sensors. Like quantum state tomography, the process tomography of an arbitrary quantum channel requires a number of measurements that scale exponentially in the number of quantum bits affected.

Quaternion representation and symplectic spin tomography [PDF]
J. Russ. Laser Res. 34, 477 (2013), 2013 Quantum tomography for continuous variables is based on the symplectic transformation group acting in the phase space. A particular case of symplectic tomography is optical tomography related to the action of a special orthogonal group. In the tomographic description of spin states, the connection between special unitary and special orthogonal groups ...
