SU-GG-I-58: A Web-Based Radiopharmaceutical Dosimetry Calculator

Abstract

Purpose: The growing interest in patient doses has led to more frequent requests for estimates of the dose imparted to patients by nuclear medicine procedures. A Web‐based computer application has been developed to facilitate timely response to such requests and to enable easy access to dosage‐specific dose estimates within our institution. Method and Materials: This system consists of two programs written in the Java programming language. The first is a Java application that is a graphical editor to produce dosimetry data files formatted in the Extensible Markup Language (XML). The dosimetry data files for a wide variety of radiopharmaceuticals have been derived from ICRP 53, ICRP 80, and CR‐6345 data tables, Russell's and Stabin's fetal dosimetry estimates, package inserts and OLINDA outputs. The second program is a Java applet that takes as input the administered activity and presents a table of doses to the organs specified in the dosimetry data file. The user may then produce a report with a variety of optional information, such as patient‐ or study‐specific details, and save it as an HTML‐formatted document for printing or as a comma‐separated‐value (CSV) formatted file for importing into a spreadsheet program. The Java applet may be served within a stand‐alone Web page or embedded in a Web page such as one from an electronic procedure manual. Results and Conclusion: This application enables the user to access the dose calculator from any Java‐enabled Web browser in our institution and quickly and easily to produce radionuclide internal dosimetry estimates that are specific to a patient's administered activity.
