Automated Erythema Quantification in Radiation Therapy - a Java Based Tool
Journal Title: Applied Medical Informatics - Year 2010, Vol 26, Issue 1
Abstract
[i]Introduction[/i]: In radiotherapy, erythema is a common side-effect, especially during radiotherapy treatment regimes that last several weeks. The measurement of erythema might be of clinical relevance, especially when standardized interpretation is possible. [i]Aim[/i]: The aim of this article is to present a tool that can be implemented for automatized and time efficient quantification of erythema from digital images taken during radiotherapy treatment. [i]Method[/i]: Instead of relying on commercially available graphic editors and performing manual operations on the images within these programs we developed a java based tool that can automatically evaluate the “redness” of images. These erythema values receive a score number, are connected with the date and time the pictures were taken and are exported into a comma separated values (CSV) file. [i]Results[/i]: The Erythema values of images could be quickly evaluated with the developed tool. With spreadsheet software the exported file could be easily manipulated to produce graphical representations of erythema rise. [i]Conclusion[/i]: Erythema quantification from digital images can be easily performed by custom developed java tools. An automated quantification provides a method of detecting an increase in erythema that may not be visible to the naked eye.
