The IGBT has been used since the early deployment of CT scanners for the control of the gantry on which the patient is reclining as described below.

Advanced medical diagnostic equipment has revolutionized the quality of care for our society. Non-invasive imaging of the interior of the body enables the surgeon to perform operations while minimizing damage to adjacent tissue and organs. It is also used in the power supply for X-ray and Ultrasound machines. 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 as discussed below.

Computed tomography (CT) generates a three dimensional image of a patient using a large series of two dimensional images taken around a single axis of rotation. The image is generated by viewing the patient using x-ray imaging from numerous angles. A single plane of a patient is scanned from various angles in order to provide a cross-sectional image of the internal structure of that plane. A three-dimensional view can then be created by mathematical analysis that combines the images. The gantry on which the patient is reclining is positioned using closed loop feedback control of motors in order to accurately move and position the patient.

An IGBT-based motor drive is employed by all manufacturers, such as GE, Philips, and Siemens, for precise and controlled movement of the gantry. The CT scanner contains an X-ray tube with detectors located diametrically opposite the X-ray source which are rotated around the patient to generate a section image. CT scanners can provide detailed cross-sectional images of nearly every part of the human body including the brain, neck, shoulders, cervical spine, heart, lungs, abdomen, liver, kidney, pelvis, etc.

IXYS received FDA approval for its IGBT in portable defibrillators, making it the leading provider of chips for defibrillators made in North America. IXYS market position is bolstered by regulatory hurdles (FDA approval) that essentially act as a barrier to entry. Additionally, IXYS power semis are being designed into advanced diagnostic systems (MRIs, x-rays, ultrasound, surgical lasers); the chips control the immediate high voltage power demands of this equipment.

Www.USComponent.com had been selling IGBT power transistor modules since 2001. Its customer includes GE, Philips, Toshiba and Siemens and other leading companies.

Www.USComponent.com have a Quality Control Team like no other. This means that we know how to work hard in order to ensure to make sure that the quality of all of the parts were selling is high. Because we only sell new and original electronic parts, we provide our customers with a 30-day warranty. And because we have connections with IGBT power transistor modules manufacturers, OEMs and distributors, were able to pass any savings on to our customers, giving them a lower price while still providing them with the quality products they deserve. Our inventory is carefully managed and held to the highest standards, and stored in a controlled environment warehousing facility.
