X-Ray machine control with wireless based on mA parameters

Abstract

An x-ray machine is a medical device that is used as a diagnostic tool for patients. The conventional x-ray machine consists of a control system, high voltage and tube x-ray machine. The control system on conventional x-ray machines uses too many cables so it looks less efficient. Control of the x-ray machine must be carried out in the same room as the equipment so that it can endanger the radiographer when it will be operated, because the radiographer will be continuously exposed to radiation. Therefore, an x-ray machine control system is designed that is safe for radiographers when operated and efficient in the use of cables. This research method uses the Arduino application to change the conventional control system to wireless, with the aim of providing the radiographer’s safety because he operates the device from a separate room and does not face the x-ray machine directly. Current selection uses several contactors at each different current. The contactor is controlled by a microcontroller connected by a series of drivers. The process of selecting voltage, current and time is carried out on a Personal Computer (PC) connected to the controller via Bluetooth. The test is done by measuring the output voltage of the filament transformer using an AVO meter, then comparing it with the voltage calculation results obtained from the x-ray machine tube specifications. Based on the tests that have been done, it is found that the correction value is small and does not deviate much, which is 0.01 V when selecting mA 50 and 0.09 V when selecting mA 60. The x-ray machine can be controlled wirelessly using a PC with a distance 6 meters in conditions blocked by a 9 cm thick wall.
