An MRI (Magnetic Resonance Imaging) scanner consists of several main components that work together to produce detailed images of the body's internal structures. The key parts include: Magnet: The powerful magnet generates a strong magnetic field, typically measured in Tesla, to align the protons in the body's tissues. Radiofrequency Coils: These are used to emit radio waves that disturb the aligned protons, causing them to emit signals that are detected by the scanner. Gradient Coils: These coils create varying magnetic fields, allowing spatial localization of the signals, enabling 3D imaging. Computer System: The MRI scanner's computer processes the signals and constructs detailed images of the body, which can be interpreted by radiologists or physicians. These essential components work in tandem to create precise and valuable diagnostic images during an MRI scan.
