Advanced MRI (Magnetic Resonance Imaging) Scanning and Image Theory Concepts: Four Reports on Unified Therodynamics of MRI, the FACTORR-Theorem, and Dynamic Range Constraints

摘要

The system configuration and performance criteria for magnetic resonance imaging (MRI) systems can be expressed in a very general way, independent of the specifics of any particular design. Four sections describe an approach to understanding global imaging features by considering the free-information energy in an image, how these considerations influence MRI system architecture, terms in the general description which are irreversible degrading to image quality in relation to the hardware defects generating them, and a proposal on remedying some of the more serious dynamic range limitations by intelligent control of data acquisitions.
