Generating synthetic computed tomography for radiotherapy: SynthRAD2025 challenge report

Viktor Rogowski, Maarten L. Terpstra, Niklas Wahl +30

Radiation therapy (RT) requires precise dose delivery over multiple fractions, with CT fundamental for treatment planning due to its electron density information. Repeated CT acqui…

Impact of deep learning model uncertainty on manual corrections to auto-segmentation in prostate cancer radiotherapy

Viktor Rogowski, Angelica Svalkvist, Matteo Maspero +12

Background: Deep learning (DL)-based organ segmentation is increasingly used in radiotherapy, yet voxel-wise DL uncertainty maps are rarely presented to clinicians. Purpose: This s…

Exploring contrast generalisation in deep learning-based brain MRI-to-CT synthesis

Lotte Nijskens, Cornelis, AT van den Berg +2

Background: Synthetic computed tomography (sCT) has been proposed and increasingly clinically adopted to enable magnetic resonance imaging (MRI)-based radiotherapy. Deep learning (…

Overcoming data scarcity through multi-center federated learning for organs-at-risk segmentation in pediatric upper abdominal radiotherapy

Mianyong Ding, Maximilian Knoll, Semi Harrabi +7

Deep learning-based organs/structures-at-risk(OARs) auto-contouring models can improve radiotherapy workflows, but models trained on adult data often underperform in pediatric pati…

Generating Synthetic Computed Tomography for Radiotherapy: SynthRAD2023 Challenge Report

Evi M. C. Huijben, Maarten L. Terpstra, Arthur Jr. Galapon +56

Radiation therapy plays a crucial role in cancer treatment, necessitating precise delivery of radiation to tumors while sparing healthy tissues over multiple days. Computed tomogra…

Dose evaluation of fast synthetic-CT generation using a generative adversarial network for general pelvis MR-only radiotherapy

Matteo Maspero, Mark H. F. Savenije, Anna M. Dinkla +5

To enable magnetic resonance (MR)-only radiotherapy and facilitate modelling of radiation attenuation in humans, synthetic-CT (sCT) images need to be generated. Considering the app…
