Wireless X-ray Machine Control Based on Arduino with Kv Parameters

Abstract

High voltage (kV) on an X-ray machine is the voltage produced by the High Tension Transformer (HTT) which will give a potential difference to the X-ray machine's tube. Regional General Hospitals (RSUD) in Indonesia still widely use X-ray machines with analog systems as kV selection. This will result in the radiographer being exposed to radiation continuously when running the X-ray machine because they have to operate the tool directly. The many uses of cables on analog systems are still less efficient, therefore a wireless X-ray machine controller is designed that can reduce radiation exposure to radiographers, and reduce the use of cables on X-ray machines. This study uses Personal Computer (PC) as a place to set parameter values, namely kV. Serial communication using Bluetooth HC-05, minimum system uses ATmega 328p IC and data processing on PC using Delphi application. Measurements on the device use a multimeter to determine the input voltage for HTT. The measurement results of the parameters 60 kV, 65 kV, 70 kV, 75 kV, and 80 kV obtained the smallest correction value is 0.15 kV on the 75 kV parameter and the largest is 1.66 kV on the 65 kV parameter. The correction value is still within the tolerance value range of ± 1kV. In the measurement of distance the farthest results obtained by 6 meters with a barrier wall thickness of 9.5 cm.
