Abstract
Radiation delivered to an object (13) is gathered by a detector unit (91). A central processing unit (18) reverse calculates the radiation delivered by using attenuation factors of the object (13) and exit radiation signals (92) generated by the detector unit (91). The delivered radiation is displayed on the screen of a monitor (70). Simultaneously, a radiation map from a planning system can be displayed. Thus, the amount of radiation delivered to object (13) is measured and can then be verified and displayed. A portal imaging system (90) can contain detector unit (91).
