Mathematical Methods in Tomography: Proceedings of a Conference Held in Oberwolfach, Germany, 5-11 June, 1990

The conference was devoted to the discussion of present and
future techniques in medical imaging, including 3D x-ray CT,
ultrasound and diffraction tomography, and biomagnetic ima-
ging. The mathematical models, their theoretical aspects and
the development of algorithms were treated. The proceedings
contains surveys on reconstruction in inverse obstacle scat-
tering, inversion in 3D, and constrained least squares pro-
blems.Research papers include besides the mentioned imaging
techniques presentations on image reconstruction in Hilbert
spaces, singular value decompositions, 3D cone beam recon-
struction, diffuse tomography, regularization of ill-posed
problems, evaluation reconstruction algorithms and applica-
tions in non-medical fields.
