Iterative projected gradient descent for dynamic PET kernel reconstruction
Alan Miranda, Steven Staelens
Dynamic positron emission tomography (PET) reconstruction often presents high noise due to the use of short duration frames to describe the kinetics of the radiotracer. Here we int…

Whole body dynamic PET kernel reconstruction using nonnegative matrix factorization features
Alan Miranda, Steven Staelens
The kernel reconstruction is a method that reduces noise in dynamic positron emission tomography (PET) by exploiting spatial correlations in the PET image. Although this method wor…
