ANALISIS ISODOSIS TEKNIK TIGA DIMENSI DENGAN LAPANGAN KRANIOSPINAL PADA PASIEN ANAK

Craniospinal is known as the method to kill cancer within a wide radiation area, starting from cranial spinal nervous system. In case, has spread through fluid of cerebro spinalis, such medulloblastoma. We carried out research determine isodose curve in medulloblastoma craniospinal patients and DVH (Dose Volume Histogram) statistic OAR (Organ at Risk) by using 3D-CRT radiotherapy technique. To conduct radiative treatment, we used moving Junction which was divided into three Iso section, i.e.: Section brain with gantry 90° 270°, thoracic 0°, lumbar 0°. Then, analyzed curves statistics created photon beams 6 MV 10 without considering dose absorbed OAR. found that were better than those dose. also tolerance limit stated ICRU guidelines.
