Description
K-SPACE AND IMAGE FORMATION IN MAGNETIC RESONANCE IMAGING
Book Summary
This manual offers a clear and concise explanation of the fundamental concept of K-space in magnetic resonance imaging, an essential tool for understanding how medical images are generated. The reader will discover the nature of the raw data captured by the coils, the excitation process via radiofrequency pulses, and the relationship between the nuclear precession frequency and the formation of the final image. A technical and didactic work for professionals and students in the field.
What is it about?
The book focuses on breaking down the image formation process in magnetic resonance from K-space, the raw data matrix that contains the magnetization information of the studied object. It explains how radiofrequency pulses, emitted in the 1-100 MHz range in medical equipment, excite atomic nuclei, which absorb energy when the pulse frequency matches their precession frequency. From there, it details how this raw data is transformed into diagnostic images, linking the underlying physics with clinical practice.
Main Topics
- Definition and structure of K-space as a raw data matrix in magnetic resonance imaging.
- Nuclear excitation process via radiofrequency pulses and energy absorption.
- Nuclear precession frequency and its relationship with signal formation.
