Abstract
MRI Scanner is widely used diagnostic tool, used in the diagnosis of diseases and results non-invasive way of imaging. This imaging technique is based on NMR imaging. The MRI system has multiple complex subsystems. The subsystems implemented are RF power amplifier, Coils, Couch, Gradient and, Magnet. This paper focuses on the development of 1 kW RF power amplifier system for 63.87 MHz at 1.5 T, with a feedback control mechanism to ensure the critical parameters of amplifier are operated within safety limit to avoid any damage. To monitor and control these parameters Graphical User Interface has been developed in LabView.
