A Prototype of an Accurate and Simple System for the Measurement of Actual Object Size from Roentgenographic Images

Abstract

Background and objective  : The magnification in an x-ray image is generally accepted; however, the finding of an actual size of an object from the x-ray image is often difficult. Using the prototype of an accurate and simple system for finding an actual object size in x-ray images can ease the difficulties. Thus, the researchers created the prototype of an accurate and simple system for finding an actual object size in x-ray images.

Methods : The researchers have developed a reference ruler and software. The two methods of taking X-ray images are as follow; fixed object-film distance and fixed x-ray tube-film distance. Then, the results from the prototype were compared to the actual size of the objects.

Results : The experimental results were more than 99 percent accurate. There were no differences between intraobserver and interobserver.

Conclusion : This prototype is very efficient, accurate, simple and cost effective. It should be suitable for all hospitals.
