Hornak's Principles of Magnetic Resonance
Hornak's Principles of Magnetic Resonance explain how magnetic resonance imaging (MRI) works, primarily focusing on the behavior of atomic nuclei in a magnetic field. When placed in this field, certain nuclei, like hydrogen in water, resonate at specific frequencies. By applying radiofrequency pulses, these nuclei are disturbed, then return to their original state, releasing energy that can be detected. This energy varies based on surrounding tissue, enabling the creation of detailed images of internal structures. Essentially, it provides a non-invasive way to visualize the body's soft tissues, valuable in medical diagnostics.
