: A unified model designed for thoracic (chest) OARs . It uses a shared "encoder" to understand general anatomy and multiple "decoders" to pinpoint specific organs, reducing the workload for radiation oncologists by up to 90%.

: A cognitive informatics model (Object-Attribute-Relation) used in AI and brain science. : A unified model designed for thoracic (chest) OARs

Researchers are focused on using neural networks to "contour" or outline healthy organs near tumors to prevent radiation damage. Significant papers and systems include: Researchers are focused on using neural networks to

: A specialized deep learning model for abdominal OARs , which outperformed several standard architectures like UNet and DeepLabV3+ in accurately contouring 16 different organs. Other Potential Meanings : A system that delineates

: Recent studies, such as those published in the Journal of Applied Clinical Medical Physics , suggest that deep-learning-generated OARs are now high enough quality to be used in treatment planning with almost no manual editing. Other Potential Meanings

: A system that delineates 42 different head and neck OARs. It uses a stratified approach, categorizing organs as "anchor," "mid-level," or "small & hard" to improve accuracy across varying sizes.
