Flywheel-Powered Mobile X-Ray Generator.
Abstract
Medical x ray machines require high power for good images without motion artifacts. Power requirements are 5 kWp for small image fields and 15 kWp for larger fields, beyond the capacity of a small field generator. Conventional batteries and high voltage capacitors can be used to accumulate energy but have practical limitations of size or affect x-ray beam quality. Circuits and mechanical components have been developed which use small flywheels with certain alternators. Aircraft alternators were used as both motors and generators to accumulate energy at a slow rate and release the energy in a short burst suitable for operating a diagnostic x-ray machine. The flywheel alternator assembly accumulated energy from a 0.5 kW source and released it in bursts in excess of 35 kWp (regulated) and 50 kWp (unregulated). Keywords: X ray, Energy storage, Flywheel powered.
