Introduction to Brain and Medical Images [PDF]
This article is based on the first chapter of book Chung (2013), where brain and medical images are introduced. The most widely used brain imaging modalities are magnetic resonance images (MRI), functional-MRI (fMRI) and diffusion tensor images (DTI). A brief introduction to each imaging modality is explained.

Object-related activity revealed by functional magnetic resonance imaging in human occipital cortex.
The stages of integration leading from local feature analysis to object recognition were explored in human visual cortex by using the technique of functional magnetic resonance imaging. Here we report evidence for object-related activation.

Charged Particle Resonance In Induction Field [PDF]
Starting from First Principles, the space charge manipulation of charged particles in an induction field in free space based on an unique Magnetic field strength and its oscillation Frequency relationship is demonstrated numerically and theoretically. The Larmor precession frequency for a time varying magnetic field, instead of conventionally followed ...
