IGBT in MRI Machines

Magnetic resonance imaging (MRI) is an important diagnostic tool commonly used in hospitals to determine the nature of injuries and status of organs in patients. Unlike CT scans, no radiation occurs when using an MRI procedure. In an MRI machine, a powerful magnetic field is used to align the magnetization of some atoms in the body, and radio frequency fields are used to systematically alter the alignment of this magnetization. The nuclei in selected atoms produce a rotating magnetic field detectable by the scanner which is used to construct an image of the scanned area of the body. MRI is especially useful in imaging the brain, muscles, heart, and cancers compared with other medical imaging techniques such as computed tomography (CT) or X-rays. It can detect aneurysms, damage to the heart or blood vessels, torn ligaments, and to find tumors. Commencing medical diagnostic equipments has revolutionized the quality of care for mankind. Non-invasive imaging of the interior of the body enables the surgeon to perform operations while minimizing damage to adjacent tissue and organs. The IGBT has been used since the early deployment of MRI scanners for the control of the gantry on which the patient is reclining as described below. In addition, hundreds of thousands of lives are being saved due to the availability of portable defibrillators which require IGBTs for delivering the controlled shock to the patient of cardiac arrest.
