In compressive sensing, prior information about the sparse representation's support reduces
the theoretical minimum number of measurements that allows perfect reconstruction. This …

Magnetic resonance imaging (MRI) machines allow one to acquire medical images based
on static and variable magnetic fields, in such a way as to reveal the interior of human …

This dissertation introduces the theory of compressive sensing with prior information about a
signal's sparse representation. We show, mathematically and in numerical simulations, that …

Compressive sensing (CS) allows for the reconstruction of sparse signals based on
measurements acquired at sub-Nyquist sampling rates. Amongst the common CS methods …

Computed tomography (CT) and positron emission tomography (PET) allow many types of
diagnoses and medical analyses to be performed, as well as patient monitoring in different …
