Abstract

The invention provides a system and method for verifying a primary radioactive dose distribution curve and a storage medium. The system and method for verifying a primary dose distribution curve generated by a radiation machine by using cloud-based services are discussed. An illustrative system may comprise: cloud, which is used for providing the cloud-based services; and a user interface, which is used for enabling a plurality of occupants to access the cloud-based services. File service can be used for extracting image information and information on the radiation machine from a DICOM file of a sufferer. Dose engine service can be used for determining a secondary radioactive dose distribution curve through applying a dose algorithm to the image information and the information on the radiation machine. The applied dose algorithm can be different from that of the radiation machine for generating the primary dose distribution curve. Dose evaluating service can be used for indicating and verifying the accuracy of the primary dose distribution curve based on consistency between the primary dose distribution curve and a secondary dose distribution curve by using the secondary radioactive dose distribution curve.

Description

technical field [0001] The present invention relates generally to dose management in radiation therapy treatment systems, and more particularly to systems and methods for validating radiation dose distribution curves using cloud services. Background technique [0002] Radiation therapy (or "radiation therapy") can be used to treat cancer or other diseases in mammalian (eg, humans and animals) tissues. One such radiotherapy technique is provided that uses a linear accelerator (also referred to as a "linac") whereby tumors are irradiated with high-energy particles (eg, electrons, protons, ions, high-energy photons, etc.). The placement and dose of the radiation beams can be precisely controlled to ensure that the tumor receives the prescribed radiation, and the beams should be placed so as to minimize damage to surrounding healthy tissue, often referred to as the organ at risk (OAR). Similar to prescribing drugs, physicians prescribe a predetermined amount of radiation dose t...
