摘要: The insulated gate bipolar transistor (IGBT) is used in the power supplies for medical diagnostic equipment such as X-ray machines and CT scanners. quality of images enhanced by excellent regulation voltage delivered to tube IGBT-based supply. It drive gradient coils MRI obtain sectional body. drives transducers ultrasound neonatal care. lasers LASIK surgery utilize IGBTs. enabled creation portable defibrillators resuscitation victims cardiac arrest. biphasic waveform applied victim controlled IGBT.
