Prototype of wireless Kv control system on x-rays machine.

A high voltage (kV) on the x-ray device is necessary to create x-ray radiation. High voltage (kV) is created by the High Tension Transformator (HTT), which increases the Alternating Current (AC) voltage from the Volt (V) scale to Kilo Volt (kV). However, many regional public hospitals in Indonesia continue to employ X-ray equipment with analog kV selection systems. As a result, radiographers will be continuously exposed to radiation since they must directly operate the instrument. This project aims to develop a wireless kV controller prototype for x-ray equipment to decrease radiographers' radiation exposure. This study methodology comprises four major phases: hardware design, software design, voltage suitability testing on x-ray instruments, and wireless remote-control testing. This study uses Android smartphones to set the kV parameter. The WEMOS D1 MINI and the Arduino MEGA 2560 microcontroller are used for serial connection. The selectable kV options are 40kV, 50kV, 60kV, and 70kV, whose outputs are emulated with 300V, 350V, 400V, and 450V. The largest adjustment is +9.263V at the 60kV level, while the smallest is +2.316V at the 40kV setting. The adjustment value is still within the 5 percent tolerance value limit. With a barrier wall thickness of 14 centimetres, the farthest distance measured was 20 meters. [ABSTRACT FROM AUTHOR]
