The power of prediction: spatiotemporal Gaussian process modeling for predictive control in slope-based wavefront sensing
Jalo Nousiainen, Juha-Pekka Puska, Tapio Helin +2
Time-delay error is a significant error source in adaptive optics (AO) systems. It arises from the latency between sensing the wavefront and applying the correction. Predictive con…
Bayesian design of measurements for magnetorelaxometry imaging
Tapio Helin, Nuutti Hyvönen, Jarno Maaninen +1
The aim of magnetorelaxometry imaging is to determine the distribution of magnetic nanoparticles inside a subject by measuring the relaxation of the superposition magnetic field ge…
Edge-promoting adaptive Bayesian experimental design for X-ray imaging
Tapio Helin, Nuutti Hyvönen, Juha-Pekka Puska
This work considers sequential edge-promoting Bayesian experimental design for (discretized) linear inverse problems, exemplified by X-ray tomography. The process of computing a to…
Sequentially optimized projections in X-ray imaging
Martin Burger, Andreas Hauptmann, Tapio Helin +2
This work applies Bayesian experimental design to selecting optimal projection geometries in (discretized) parallel beam X-ray tomography assuming the prior and the additive noise…
