Abstract

Today, we have many important problems in the field of high energy radiotherapy. One of these problems is to controll the flatness of X-ray dose in the treatment field. The usually used instrument for measurement of the beam-flatness was complicated and took much toil to operate. We overcome these difficulties by constructing a new type of equipment for measuring of beam flatness, which is light, compact and easily handled. Here, we show the construction of this equipment, its advantages and the results of our experiments using this apparatus.
