Phys Med Biol
. 2025 Jan;
70(6).
PMID: 39842088
Internationally, reference dosimetry for clinical proton beams largely follows the guidelines published by the International Atomic Energy Agency (IAEA TRS-398 Rev. 1 (2024). This approach yields a relative standard uncertainty...

96(1146):20230058.
PMID: 37102707
Objectives: To identify variables predicting interfractional anatomical variations measured with cone-beam CT (CBCT) throughout abdominal paediatric radiotherapy, and to assess the potential of surface-guided radiotherapy (SGRT) to monitor these changes....

Phys Med Biol
. 2023 Mar;
68(10).
PMID: 36996837
. Adaptive radiotherapy workflows require images with the quality of computed tomography (CT) for re-calculation and re-optimisation of radiation doses. In this work we aim to improve the quality of...

Phys Imaging Radiat Oncol
. 2021 Jul;
19:45-52.
PMID: 34307918
Background And Purpose: State-of-the-art radiotherapy modalities have the potential of reducing late effects of treatment in childhood cancer survivors. Our aim was to investigate the carcinogenic risk associated with 3D...

Phys Med Biol
. 2021 Mar;
66(10).
PMID: 33735848
Reducing radiation-induced side effects is one of the most important challenges in paediatric cancer treatment. Recently, there has been growing interest in using spatial normalisation to enable voxel-based analysis of...
