This study aimed to develop the virtual x-ray machine for educational purpose. The machine can demonstrate the internal x-ray inserted tube structure while operating is being done without x-ray output for safety learning and teaching. The machine was controlled by PIC microcontroller manufactured from Microchip Technology Inc. Company. Internal firmware was developed by using C-language “MikroC Pro for PIC” compiler from Mikroelectronika D.O.O. Company. The developed machine was designed to adjust 3 exposure parameters; virtual x-ray tube voltage from 40 to 140 kVp, the virtual tube current in 3 levels at 100 mA, 200 mA and 300 mA, and exposure time from 0.01 second to 2.00 second in 21 steps. Finally, it consists of “Bucky system” for reducing scatter ray and rotating anode braking system which is especially designed to coast down the rotating anode to stop rotate in 10 second for rapid observation.
