Motion Correction and Pharmacokinetic Analysis in Dynamic Positron Emission Tomography
(Johns Hopkins University, 2015-02-20)
This thesis will focus on two important aspects of dynamic Positron Emission Tomography (PET): (i) Motion-compensation , and (ii) Pharmacokinetic analysis (also called parametric imaging) of dynamic PET images. Both are ...
Minimizing Nonconvex Quadratic Functions Subject to Bound Constraints
(Johns Hopkins University, 2014-12-11)
We present an active-set algorithm for finding a local minimizer to a nonconvex bound-constrained quadratic problem. Our algorithm extends the ideas developed by Dost al and Sch oberl that is based on the linear conjugate ...
