      abstract     = {To assess the feasibility of performing dose measurements
                      in the target (prostate) and an adjacent organ at risk
                      (rectum) using polymer dosimetry gel and thermoluminescence
                      detectors (TLDs) in an anthropomorphic, deformable and
                      multimodal pelvis phantom (ADAM PETer).The 3D printed
                      prostate organ surrogate of the ADAM PETer phantom was
                      filled with polymer dosimetry gel. Nine TLD600 (LiF:Mg,Ti)
                      were installed in 3x3 rows on a specifically designed
                      3D-printed TLD holder. The TLD holder was inserted into the
                      rectum at the level of the prostate and fixed by a partially
                      inflated endorectal balloon. Computed tomography (CT) images
                      were taken and treatment planning was performed. A
                      prescribed dose of 4.5 Gy was delivered to the planning
                      target volume (PTV). The doses measured by the dosimetry gel
                      in the prostate and the TLDs in the rectum ('measured dose')
                      were compared to the doses calculated by the treatment
                      planning system ('planned dose') on a voxel-by-voxel
                      basis.In the prostate organ surrogate, the 3D-γ-index was
                      $97.7\%$ for the $3\%$ dose difference and 3 mm distance to
                      agreement criterium. In the center of the prostate organ
                      surrogate, measured and planned doses showed only minor
                      deviations (<0.1 Gy, corresponding to a percentage error of
                      $2.22\%).$ On the edges of the prostate, slight differences
                      between planned and measured doses were detected with a
                      maximum deviation of 0.24 Gy, corresponding to $5.3\%$ of
                      the prescribed dose. The difference between planned and
                      measured doses in the TLDs was on average 0.08 Gy (range:
                      0.02-0.21 Gy), corresponding to $1.78\%$ of the prescribed
                      dose (range: $0.44-4.67\%).The$ present study demonstrates
                      the feasibility of using polymer dosimetry gel and TLDs for
                      3D and 1D dose measurements in the prostate and the rectum
                      organ surrogates in an anthropomorphic, deformable and
                      multimodal phantom. The described methodology might offer
                      new perspectives for end-to-end tests in image-guided
                      adaptive radiotherapy workflows.},
