Abstract
|
|
|
Radiation dosimetry has been extended to small fields less than 4×4 ㎠ which may be suitable for irradiation of small intracranial tumors.
Special consideration was given to the percentage depth dose and scatter correction factors with 0.14㎖ ion chamber, film dosimetry and TLD measurement.
Calculated dose distributions were compared with measured data.
