    DOSIsoft releases EPIbeam for pre-treatment beam verification with CE Marking

    EPIbeam is a phantom free software used to control various aspects within the external radiation therapy pre-treatment stage. Its most important function is to check the accuracy on the various beams to the TPS calculated theoretical beams, by comparing the associated EPID image to the theoretical image. The beams can then be validated and the results can be analyzed, thus making a decision on whether or not to treat the patient using them.
