The method involves irradiating a phantom, and measuring the phantom using detectors. An information unit collects information regarding the irradiation between the phantom and the radiation source. The measurements are analyzed to obtain information regarding the relationship between the measurements in the phantom and the information between the phantom and the treatment source at each time interval. The relationship information is used as verification of the treatment of the patient. An Independent claim is also included for a computer program product to enable a computer to perform the method of enabling quantification of dose delivery.
