Abstract: The present invention relates to a device enabling quantification of dose delivery in radiotherapy treatment during patient-specific treatment of the patient utilising measurements in predefined time-intervals with information means positioned in the radiation beam, between the patient and the source and converting the readings to corresponding measures in a phantom.

Abstract: Dose distribution is measured in a patient-shaped phantom with high accuracy for radiation therapy treatment verification. A detector configuration in such a phantom and improvements in measurement methodology enable application of correction factors in an accurate way.
