Open Source Radiotherapy Viewer with Verification and Approval Function for DICOM-RT Object in IHE-RO Workflow

Learning Object:To understand the principal of the DICOM-RT object and the suitabledisplay methods for the dose distribution and beam data To understand a viewing function of DICOM-RT Objects and the IHE workflow of the radiotherapy To study how to confirm the radiation planning and the dose distribution of the target and issue the approvalAbstract:Purpose:To verify the dose distribution and treatment plan is very import and inevitable for a radiation oncologist. We developed the viewing software that can display the radiotherapy data (DICOM-RT Object) for a physician. The physician can issued the approval of the radiation plan by using this software.Methods:The software was written by the java and can be updated by the Java Web Start function in a hospital. We decide that this software is distributed under the open source criteria.Results:Physicians can easily display the DICOM-RT Object (RT image, RT plan and structure set) and also share the information. If he confirmed a treatment, he can change the approval status of the DICOM-RT Object.Discussion:Using this software, radiation oncologist can confirm the treatment plan and dose distribution quickly and issue the approval of the treatment with the DICOM approval module. This process conforms to the IHE-RO scheduled workflow that is investigated by the IHE-Japan RO group.RSNA\u2706 92th Scientific Assembly and Annual Meetin
