What is Predictive Adaptive Radiation Therapy for Lung Cancer about?

Systems). The control arm of the protocol specifies 73.8 Gy to the PTV, with .98% coverage of the PTV and 100% coverage of the prostate. One plan was a 5-field SMLC plan, and the other used 7 fields. The plans were exported to the Computation Environment for Radiation Research (CERR) where the dose distributions were individually convolved with each probability distribution function to generate motion-effected dose distributions (Matlab R2006b, Mathworks, MA). The number of fractions that resulted in a minimum dose to the prostate below 73.8 Gy was recorded. Results: Convolution of each plan with the 1228 tracking sessions took 2 hours on a Pentium D 3.60 GHz machine with 3.5 Gb RAM. In both patients, plans with a uniform 5 mm margin resulted in less than 3% of the total fractions with prostate dose less than the prescription dose. In the patient with the 7-field SMLC plan, the 4 mm plan also resulted in 3% of the total fractions receiving less then prescription dose to the prostate. In the patient with the 5-field SMLC plan, the 4 mm plan resulted in 12% of the total fractions receiving less than the prescription dose to the prostate, with a range of 0-61% depending on which histo
