An Improved Design of Flat Panel Detector with Phototransistor PH101 Analysis of The Tube Voltage Setting

The intensity and quality of the X-Rays a patient receives is determined by exposure factor. Voltage (kV), Current (mA), Time (seconds), tube-to-film distance (FFD) are factors that can be controlled determined. key factor determine tube voltage (kV) which affects to penetrate objects. purpose this research improve image relatively affordable manufacturing costs obtaining difference in detector catch value between dark light utilizing response PH101 phototransistor sensor. contribution system display grayscale numeric on 16x16 pixel matrix using Matrix Laboratory (MATLAB) application. This convert images taken from analog data after measuring X-Rays. measurement settings used 50, 55, 60, 70kV, with current 40 mA an irradiation time 1 second. results show Flat Panel Detector Design respond differences doses shows Phototransistor sensor have been successfully made capture so black level film
