Synopsis

Keywords: Image acquisition: Sequences

MRI involves the sequential application of pulsing in RF and gradient coils, known as pulse sequences. This talk aims to explain fundamental concepts on how the gradient and RF pulsing generates an MR image. It covers the mathematical perspective of Fourier transform and the relation between the integral area of the gradient pulsing and the position in k-space. The presentation describes the combined utilization of RF and gradient pulsing for generating tomographic images, elucidating the role of a k-space trajectory in image formation. Key concepts such as slice selection, frequency encoding, phase encoding, and k-space will be explored.
