[Design and Validation of Remote Radiotherapy System].

Telemedicine technology is a means of deploying medical resources with low cost and high efficiency. A set of remote radiotherapy system based on Citrix was designed in this paper, so that the senior radiation therapists from the developed areas can provide medical services effectively for the patients in the rural areas. This paper focused on the design ideas and the detail of the technical implementation of how to design a remote radiotherapy system based on the existing equipment in the primary hospital. And the technical reliability and security of the remote radiotherapy system were verified by the scientific test method with pairwise comparison. The early practical experience shows that through the remote radiotherapy system the primary radiotherapy personnel and the radiotherapy experts from thirdgrade class-A hospital can form effective alliance in radiotherapy techniques to allow patients in rural areas to receive more professional radiation therapy.

[Porting Radiotherapy Software of Varian to Cloud Platform].

To develop a low-cost private cloud platform of radiotherapy software. First, a private cloud platform which was based on OpenStack and the virtual GPU hardware was builded. Then on the private cloud platform, all the Varian radiotherapy software modules were installed to the virtual machine, and the corresponding function configuration was completed. Finally the software on the cloud was able to be accessed by virtual desktop client. The function test results of the cloud workstation show that a cloud workstation is equivalent to an isolated physical workstation, and any clients on the LAN can use the cloud workstation smoothly. The cloud platform transplantation in this study is economical and practical. The project not only improves the utilization rates of radiotherapy software, but also makes it possible that the cloud computing technology can expand its applications to the field of radiation oncology.

[Development of a Software for Automatically Generated Contours in Eclipse TPS].

OBJECTIVE: The automatic generation of planning targets and auxiliary contours have achieved in Eclipse TPS 11.0. METHODS: The scripting language autohotkey was used to develop a software for automatically generated contours in Eclipse TPS. This software is named Contour Auto Margin (CAM), which is composed of operational functions of contours, script generated visualization and script file operations. RESULTS Ten cases in different cancers have separately selected, in Eclipse TPS 11.0 scripts generated by the software could not only automatically generate contours but also do contour post-processing. For different cancers, there was no difference between automatically generated contours and manually created contours. CONCLUSION: The CAM is a user-friendly and powerful software, and can automatically generated contours fast in Eclipse TPS 11.0. With the help of CAM, it greatly save plan preparation time and improve working efficiency of radiation therapy physicists.
