Article Synopsis
- - The study analyzed 10 years of treatment planning error data collected by medical physicists, focusing on high-risk errors, the impact of treatment volume on error rates, and the effectiveness of an Automated Plan Checking System (APCS).
- - Findings indicated that using APCS reduced error rates by around 1% for high-risk errors and 3% for low-risk errors, and there was an inverse relationship between the number of treatments and error rates.
- - The research also revealed that high workloads among medical physicists and a higher number of less experienced physicians were linked to increased error occurrences, emphasizing the need for adequate training and additional plan checkers to mitigate these errors.

Article Synopsis
- - This study investigates how the movement of the liver during breathing affects the accuracy of stereotactic body radiation therapy (SBRT) for patients with spine metastasis, particularly looking at treatment plans for patients with liver lesions.
- - Researchers analyzed treatment plans for 15 patients using CT scans taken during both inhalation and exhalation to assess how liver motion impacted radiation dosage delivered to the spine and surrounding tissues.
- - Their findings suggest that without incorporating strategies like beam avoidance, the liver's movement can result in significant radiation dose discrepancies, especially affecting the spinal cord, highlighting the need for careful evaluation of respiratory management during treatment.
Article Synopsis
- Previous plan competitions primarily assessed dose metrics, but the actual quality assurance (QA) aspects of submitted plans were uncertain.
- This study aimed to explore the relationship between plan complexity metrics (PCMs) in volumetric modulated arc therapy (VMAT) competition plans and clinically verified treatment plans through patient-specific QA.
- The findings indicated that while there was a weak correlation between dose distribution quality and PCMs, high-quality competition plans showed increased complexity, suggesting that the submitted plans can be considered realistic and reasonable from a QA perspective.

April 2023
Article Synopsis
- The study focuses on improving the setup process of lung shields (LS) used in total body irradiation (TBI) by evaluating a new mobile imaging system (TBI-MI) that offers real-time monitoring.
- Evaluations included measuring displacement accuracy, image quality, and the system's ability to detect patient movement during the procedure, with the TBI-MI proving effective and reliable.
- Results indicated that the TBI-MI can provide acceptable image quality while enhancing patient safety through better monitoring capabilities during TBI treatments.
Article Synopsis
- Boron Neutron Capture Therapy (BNCT) is gaining traction in cancer treatment due to advancements in accelerator-based systems, but detailed processes for these systems are still lacking.
- * The study aims to assess potential risks associated with implementing accelerator-based BNCT systems through a detailed failure mode and effects analysis (FMEA) involving a diverse medical team.
- * A total of 165 failure modes were identified, with 30 classified as high risk and 17 as very high risk, highlighting the importance of education and training for staff as the number of BNCT facilities grows.*
