    Evaluation of the accuracy of deformable image registration on MRI with a physical phantom
  6. 2426
    “…Purpose: Proton radiotherapy (PRT) is potentially associated with a lower risk for secondary malignancies due to a decreased integral dose to the surrounding organs at risk (OARs). Prospective trials confirming this are lacking due to the need for long-term follow-up and the ethical complexities of randomizing patients between modalities. …”

    Cardiac dose in the treatment of synchronous bilateral breast cancer patients between three different radiotherapy techniques (VMAT, IMRT, and 3D CRT)
  16. 2436
    “…Likewise, lower mean SC doses with 1F2S‐18MV were observed in comparison to the more treatment time‐consuming 3D‐CRT techniques (1F4S, WD) and the original plans without relevant compromises on the dose homogeneity in the target volume and the dose exposure to the other OARs. CONCLUSION: In treatment planning of spinal metastases, simple variants of 3D‐CRT‐techniques like 1F2S‐18MV can offer a significant dose limitation to the SC while providing a sufficient dose coverage of the target volume. …”
