 Abstract: Magnetic Resonance techniques rely on three different types of magnetic fields for signal generation. The magnet generates a uniform static main field, so that forms the initial equilibrium condition of a longitudinal net magnetization in the sample and maintains Larmor precession of nuclear spins at a constant angular frequency. Linear magnetic field gradients in 3 dimensions can be switched at and thus generate a position dependence of the Larmor frequency. The radio-frequency (RF) coils can transmit a
magnetic field of short duration in a direction perpendicular to the main field that excites the spins and generate transverse magnetization. As the spins return to the inditial condition, an electromotor force is induced in the same or in specifically designed receiving RF-coils. Besides these basic pieces, an MR system needs an appropriate hardware and software architecture in order to: control working conditions of the basic hardware synchronize the generation and acquisition of transverse magnetization generate MR images from the acquired signal.
