Introduction to MRI Machines: Different Types Of Mri Machines
MRI machines are sophisticated medical imaging devices that use powerful magnets, radio waves, and computer algorithms to create detailed images of the internal structures of the body without causing any harm. The principle of MRI technology is based on the phenomenon of nuclear magnetic resonance (NMR), which was first discovered in the early 20th century.
The working principle of MRI machines involves the alignment of atomic nuclei in the body, which are then exposed to a magnetic field and rf pulses. This causes the nuclei to emit signals, which are detected by the machine and used to create detailed images of the body.
Basic Components of an MRI Machine
A typical MRI machine consists of several key components, including the magnetic field assembly, the rf coil, the computer system, and the patient table. The magnetic field assembly is the strongest part of the machine, creating a powerful magnetic field that aligns the atomic nuclei in the body. The rf coil is responsible for generating the rf pulses that cause the nuclei to emit signals. The computer system processes the data collected by the machine to create detailed images of the body. The patient table is a movable platform that allows patients to be positioned correctly within the machine.
