Abstract

The invention discloses a cloud-computing based dose verification system and method of tumor radiotherapy. The system comprises a user terminal equipment, a cloud computing server, a local therapy planning system, a computer, an HDFS data storage server and a medical linear accelerator. According to the system and method, EPID information collection is separated from dose analysis and comparison, and part which needs computing and analyzing is transferred to the server based on cloud computer; the equipment at the user end only makes therapy plans, collects, pre-processes and transmits EPID images and receives and display analysis results; and Gamma analysis between to-be-compared dose distribution and reference dose distribution is accelerated. The parallel operation mechanism of cloud computing is used, so that planning dose verification of tumor radiotherapy can be greatly accelerated, time of clinical dosimeter verification is reduced, and the efficiency of radiotherapy is improved.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a cloud computing-based dose verification system and method for tumor radiotherapy, and relates to the field of medical technology and cloud computing technology. The present invention applies cloud computing to the analysis process in the dosimetry verification of radiotherapy plans. Through cloud computing, more computing units can be executed in parallel at the same time, which shortens the computing time, improves the speed of dosimetry verification, and can effectively Realized the verification of online radiotherapy plan effectively. Background technique [0002] The whole process of tumor radiation therapy is mainly divided into the design stage of treatment plan and the execution stage of treatment plan. The portal imaging system is an important quality assurance tool in the implementation stage of the treatment plan. Its main function is to observe, record and reproduc...
