- Abstract
- The amount of potentially lethal damage repair (PLDR) is a significant factor in the process of modeling the survival curves of cells irradiated with fractionated carbon beams. Because the amount of PLDR generally depends on the features of the cells and the linear energy transfer (LET), the amount of PLDR of cells irradiated with fractionated carbon beams shows distinct differences from that of cells irradiated with X-rays. This study considered a new parameter dependent on the correlation between the PLDR trait (T) of the cells over a time interval (Delta) at the fractionated carbon beam irradiation. The survival curves of the cells irradiated with fractionated carbon beams n times were predicted using the zeta and the psi values from the delay assay. This study aims to overcome the barriers of traditional methods by developing a new survival curve model with new parameters based on an analysis of the PLDR traits of cells over time interval in fractionated carbon beam irradiation and to suggest a model that produces results significantly closer to the experimental data.
