Accurately identifying needle tip and seed positions for low dose rate prostate brachytherapy on MRI images is challenging. Uncertainties in locating needle tip positions can lead to misplacement of seeds compared to planned coordinates. Furthermore

Suitability of propagated contours for adaptive replanning for head and neck radiotherapy

Autor: David, Nash, Antony L, Palmer, Marcel, van Herk, Alan, McWilliam, Eliana, Vasquez Osorio

Publikováno v: Physica medica, 102, 66-72. Associazione Italiana di Fisica Medica

Purpose: Adaptive radiotherapy relies on rapid recontouring for replanning. Contour propagation offers workflow efficiencies, but the impact of using unedited propagated OAR contours directly during re-optimisation is unclear. Methods: Plans for ten

Within the brachytherapy community, many phantoms are constructed in-house, and less commercial development is observed as compared to the field of external beam. Computational or virtual phantom design has seen considerable growth; however, physical
