A gradient magnetic field is a spatially varying magnetic field used in magnetic resonance imaging (MRI) to encode spatial information by causing the resonance frequency of nuclei to vary with position. This enables the reconstruction of detailed images by allowing the precise localization of signals within the body.

Magnetic Resonance Imaging (MRI) is a non-invasive imaging technique that uses strong magnetic fields and radio waves to generate detailed images of the organs and tissues in the body. It is widely used in medical diagnosis and research due to its ability to provide high-resolution images without exposure to ionizing radiation.

spatial information

Resonance frequency is the natural frequency at which a system oscillates with the greatest amplitude when subjected to a periodic force, due to the constructive interference of the energy input and the system's inherent oscillations. It is crucial in various fields, from engineering to physics, as it can lead to both beneficial effects, like in tuning musical instruments, and detrimental effects, such as structural failure in buildings and bridges.

Position refers to the specific location or arrangement of an object or entity in space or within a particular context. It is a fundamental concept in various fields, influencing how entities interact, relate, and are perceived in both physical and abstract spaces.

Reconstruction of images

Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic technique that uses powerful magnets and radio waves to generate detailed images of the body's internal structures, particularly soft tissues. It is widely used in medical settings for diagnosing conditions, monitoring treatment progress, and guiding surgical planning without exposing patients to ionizing radiation.
