M19. Modern Challenges in Imaging, Tomography, and Radon Transforms

Minisymposium dedicated to the 70th anniversary of an outstanding expert in inverse problems and imaging sciences, Robinson Professor of Mathematics Tufts University, Todd Quinto

Imaging, Tomography and Radon Transforms are one of the fastest developing areas of inverse problems, and they have a wide range of applications. Tomography became generally known in the seventies when medical diagnosis was revolutionized by X-ray computed tomography. The mathematical model is an integral transform and Fourier integral operator--the Radon transform. Other imaging technologies lead to more complicated integral transforms as well as linear and nonlinear problems. Classical problems, such as limited-data tomography, are still challenging. Cone-Beam tomography, ultrasound tomography, multi-modal imaging, Compton and Bragg tomography, and time-dependent problems are other frontiers of research. All these technologies have in common that the mathematical models are ill-posed inverse problems.

The minisymposium celebrates one of the pioneers of the mathematics of imaging and tomography, Prof. Eric Todd Quinto, on the occasion of his 70th birthday. It will bring together well-established scientists and young researchers to introduce new methods in the field, including the methods pioneered by Prof. Quinto.
