Abstract: Objective To develop a fixed ruler for the simulated locator to measure the distance between human organs.Methods Analyses were carried out on the problems of the existing measures of the simulated locator and clinical requirements,and then the matching of the ruler with the locator and etc were explored.The structures of the fixing hole and slots were determined,and the ruler base was selected.The ruler was composed of an organic glass plate with multi slots and multi cylindrical copper wires.Results At the isocenter of the locator,the fixed scale values of the ruler equaled to those of the ruler on the screen,and the values for multi point distances could be obtained with the fixed ruler and stored in medical image.Conclusion The fixed ruler measures the distance between human organs simply and accurately,and lays a foundation for the development of likely product.
