The resulting DRC for dicentric plus centric ring (Dic+CR) yield was fitted to the linear-quadratic model. Its applicability was explored using individual dose-volume data from 12 radiotherapy patients (5 glioblastoma, 7 breast cancer) to calculate expected Dic+CR yields, which were compared with aberration yields observed after the first treatment fraction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The phantom-based DRC showed good agreement with the linear-quadratic model across the investigated dose range. Expected Dic+CR yields calculated from patient-specific dose-volume data were of the same order of magnitude as the observed yields but were lower in 10 of 12 patients. The association between expected and observed yields was positive but not statistically significant (r = 0.39, p = 0.21),<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The proof-of-concept for inverse cytogenetic biodosimetry using phantom-based DRC in radiotherapy patients was achieved.
