Evaluation of Dose-Painting in the Dominant Intraprostatic Lesions by Radiobiological Parameters using 68Ga- PSMA PET/CT [PDF]

Journal of Biomedical Physics and Engineering, 2022
Background: Patients diagnosed with dominant intraprostatic lesions (DIL) may need radiation doses over than 80 Gy. Dose-painting by contours (DPC) is a useful technique which helps the patients. Dose-painting approach need to be evaluated. Objective: To

Modeling of dose-response relationships. [PDF]

Environmental Health Perspectives, 1981
The main dose-response models for chronic toxicity are considered. For dichotomous response, the log probit, multi-hit, and multistage models are presented. For time-to-occurrence response, the log-normal and three variations of multistage models are presented. Finally, the Cornfield hockey-stick model is considered, and, for low-dose extrapolation, it
