Organs at risk radiation dose constraints

Cancer/Radiothérapie, 2022
Dose constraints are essential for performing dosimetry, especially for intensity modulation and for radiotherapy under stereotaxic conditions. We present the update of the recommendations of the French society of oncological radiotherapy for the use of these doses in classical current practice but also for reirradiation.

Organs at risk in lung SBRT

Physica Medica, 2017
Lung stereotactic body radiotherapy (SBRT) is an accurate and precise technique to treat lung tumors with high 'ablative' doses. Given the encouraging data in terms of local control and toxicity profile, SBRT has currently become a treatment option for both early stage lung cancer and lung oligometastatic disease in patients who are medically ...

Quality organization and risk in anaesthesia

Current Opinion in Anaesthesiology, 2017
Ensuring the quality and safety of anaesthesia in the face of budgetary restrictions and changing demographics is challenging. In France, the environment is regulated by the legislation, and it is often necessary to find solutions that seize opportunities to break with the traditional organization.Postoperative mortality remains excessively high.

Organizations and Risk in Late Modernity

Organization Studies, 2009
Risk is an important but under-investigated feature of organizations in Late Modernity. This paper introduces the Special Issue on Organizations and Risk in Late Modernity. The rationale for the special issue is discussed. An overview of important approaches to risk research and organizations is provided to frame the special issue.

Delineation of organs at risk in radiotherapy and perspectives

Cancer/Radiothérapie
The delineation of organs at risk is fundamental in radiotherapy, ensuring optimal tumour targeting while minimizing toxicity to healthy tissues. Advances in imaging, including MRI-based segmentation and functional imaging, have improved contour precision, while artificial intelligence-assisted autosegmentation enhances efficiency and reproducibility ...

Anatomical contouring variability in thoracic organs at risk

Medical Dosimetry, 2016
The purpose of this study was to determine whether contouring thoracic organs at risk was consistent among medical dosimetrists and to identify how trends in dosimetrist׳s education and experience affected contouring accuracy. Qualitative and quantitative methods were used to contextualize the raw data that were obtained.

Contouring Methods and Atlas of Organs at Risk

2021
Accurate delineation and precise dosage of organs at risk (OARs) is crucial for improving efficacy and reducing toxicity of radiotherapy for nasopharyngeal carcinoma (NPC). Here, guidelines for planning OARs were presented. We suggested using specific window width and window level for recognition of organ boundary.

Organs at Risk (OAR) Tolerance in Hypofractionated Radiosurgery

2020
For CyberKnife radiosurgery, the precise interpretation of the normal probability of tissue complications (NTCP) is extremely important due to the reverse planning algorithm and the non-isocentric irradiation geometry adopted by the system, which requires the setting of dose constraints for any organ at risk (OAR).
