Abstract

Systems (500) and methods (700) for verifying a primary dose profile generated by a radiation machine using cloud-based services are disclosed. An exemplary system (500) can include a cloud (530,600) that provides cloud-based services, and a user interface (136) that enables multi-tenant access to the cloud-based services. A file service (610) can extract from a patient (501) DICOM file image information and information about a radiation machine. A dose engine service (620) can determine a secondary radiation dose profile by applying a dose algorithm (624) to the image and the radiation machine information. The applied dose algorithm (624) can be different from the dose algorithm used by the radiation machine to generate the primary dose profile. A dose evaluation service (630) can use the secondary radiation dose profile to verify accuracy of the primary dose profile based on a consistency indicator between the primary and secondary dose profiles.
