In conformation radiotherapy combined with the hollow-out technique, it is essential to select the suitable material of the absorber, as the material of the absorber influences on the dose distribution. Practically, it is necessary to shield both-sided eyes, in the treatment of carcinoma of the maxillary sinus. The distortion of the dose distribution caused with the absorption of tungsten, copper and zinc were measured. In order to shield the healthy-sided eye completely, it was suitable to use tungsten rod (2cm. in diameter) as the absorber. With the use of tungsten rod to shield the ill-sided eye, its shielding effect was excellent, while the distortion of the dose distribution could not be ignored. By using the zinc rod, the distortion of the dose distribution deviated from the expected beam focus was neglisible, on the other hand the shielding to the ill-sided eye was considerably good.
