Enhanced attenuation modelling for multispectral computed tomography
Jürgen Jeschke, Dirk Lorenz
We revisit the modelling of the material decomposition problem in multispectral computed tomography and propose to leverage the known absorption spectra of different materials. Wit…

Generalized Modulo Hysteresis Encoding
Matthias Beckmann, Jürgen Jeschke
Unlimited sensing and its extension via modulo hysteresis provide an efficient encoding scheme for high dynamic range signals by folding the signal's amplitude into the range of th…

Orthogonal Matching Pursuit based Reconstruction for Modulo Hysteresis Operators
Matthias Beckmann, Jürgen Jeschke
Unlimited sampling provides an acquisition scheme for high dynamic range signals by folding the signal into the dynamic range of the analog-to-digital converter (ADC) using modulo…
