Credentialing of small‐field dosimetry for the lung SBRT in Japan Clinical Oncology Group clinical trial

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Background Small‐field dosimetry plays a pivotal role in stereotactic body radiation therapy (SBRT), where high‐precision dose delivery is essential. In multi‐institutional clinical trials, quality assurance (QA) becomes increasingly critical due to the variability in linear accelerator (linac) output calibration and treatment planning system (

Comparison of three methods of calculation, experimental and monte carlo simulation in investigation of organ doses (thyroid, sternum, cervical vertebra) in radioiodine therapy

Journal of Medical Signals and Sensors, 2012
Radioiodine therapy is an effective method for treating thyroid cancer carcinoma, but it has some affects on normal tissues, hence dosimetry of vital organs is important to weigh the risks and benefits of this method.
