Abstract:
:Peacock is a 3-D conformal treatment planning and delivery system for conformal radiation therapy which delivers intensity-modulated fields. A group of 13 patients were treated between March and February, 1995. Patient age ranged from 10 to 74. Six of the patients had previously received radiation therapy. Target volume was from 2.5 to 70 cm3: all treatments were fractionated, using single table angle plan with 270 degrees of rotation. A removable invasive cranial screw fixation device was used in all cases. Treated isodose line averaged 85%; conformality index was better than 2, with 0-5% of critical structure volume exceeding dose limits. Setup time averaged 8 min per fraction: treatment time ranged from 10 to 80 min. There were two equipment failures in 200 fractions/1,000 gantry rotations. Patient position averaged about 1 mm within initial setup. Follow-up has revealed no complications from the radiation.
