Dicom Standard Radiotherapy

DICOM is a standard developing in the field of medical informatics. It defines a standard network interface and data model. The employment of the standard realizes the connection of the different manufactories of medical imaging devices, simplifies the development of all kinds of medical images, facilitates the transmission and exchange of medical images and urge the combination of the PACS and HIS.The intent of radiotherapy is to make use of radiation to kill tumors. It's one of the methods to cure malicious tumors. With the development of science and technology, a radiotherapy planning system comes forth. It can assist physiatrists to accurately locate the tumors and design radiotherapy plans. Many hospitals buy the radiotherapy planning systems from not more than one manufactory. We should use DICOM to exchange information among the systems.DICOM RT is the abbreviation of DICOM in Radiotherapy. Inside the country, doctors have not recognized its signification, while outside the research is under way.This thesis discusses the realization of the DICOM RT. My work include:(1) Analyze the architecture of DICOM application entity and working mechanism and implement the model of DICOM network communication based on TCP/IP. Complete the communication between 3 kinds transfer syntax: Implicit VR Little Endian, Explicit VR Little Endian, Explicit VR Big Endian. (2) Based on this network communication model, realize the fundamental DICOM service class: C-STORE service class. The C-STORE service is used by a DIMSE-service-user to store a composite SOP Instance on a peer DIMSE-service-user. It is in common use.(3) Complete partial function of DICOM RT, including RT Image, RT Structure Set and RT Plan and implement the interoperability between two different RT planning systems...
