Objective: To develop an artificial intelligence (AI) driven plan tradeoff decision making assistant for radiation oncologists. Methods: A user interface (UI) was developed to integrate the assistant with the treatment p...

Background and purpose: Artificial intelligence-based contouring tools enable assessment of radiation doses to cardiac substructures beyond mean heart dose. This study examined inter-solution variations in raw contours a...

Within the United Nations Sustainable Development Goals (UN SDGs), health and well-being are one of the most important goals. This perspective highlights recent institutional progress at Korea Institute of Radiological a...

Background and purpose: Bilateral breast or chest wall and regional nodal irradiation involves large treatment volumes adjacent to multiple critical organs. The feasibility and normal tissue sparing of proton arc therapy...

Background and purpose: Intrafraction motion degrades the efficacy of radiation therapy. We reported on the implementation of focal dose-escalated stereotactic body radiation therapy (HypoFocal-SBRT) for prostate carcino...

Background and purpose: Deviations in radiotherapy quality can significantly affect clinical trial outcomes, including overall survival. Radiotherapy quality assurance (RTQA) is a systematic process by which a RT plan is...

Objective: To identify risk factors for post-radiation xerostomia and to evaluate the tolerance to doses administered to the parotid gland in patients with nasopharyngeal carcinoma (NPC). Methods: A total of 462 patients...

Background and purpose: Mediastinal lymphoma patients are typically young and are at risk of long-term radiation-induced adverse events, making organ of interest (OOI) sparing a key objective of radiotherapy. This study ...

Background and purpose: Proton therapy is a promising modality for treating locally advanced non-small cell lung cancer (LA-NSCLC). However, respiratory-induced intra-fractional motion can compromise tumour coverage. Thi...

Background and purpose: Robust optimization mitigates the effects of range and setup uncertainties in intensity–modulated proton therapy (IMPT) through robustness settings. However, it increases the dose to organs-at-r...

Background and purpose: Previous studies have demonstrated that mini-ridge filters (MRF) can reduce beam delivery time in pencil beam scanning (PBS) proton therapy, but the effect on plan quality has not been analyzed in...

Background and purpose: Oesophageal radiotherapy may cause side effects due to high organs of interest (OOIs) doses. While proton therapy (PT) reduces OOI dose compared to photon therapy, setup robustness settings used m...

Resumen: En los últimos años, la concepción tradicional de la radioresistencia del carcinoma de células renales ha ido cambiando. Esto gracias al desarrollo de la radioterapia estereotáxica corporal (SBRT) como una ...

Objective: To explore the imaging biomarkers obtained from baseline multi-modality imaging PET/CT before metastasis-directed therapy (MDT), which could offer early response prediction before MDT treatment, optimizing pat...
