ABAS® Atlas-Based
Autosegmentation

Automated contouring and segmentation

Manual contouring is a time-consuming component of the treatment planning process. Elekta's Atlas-Based Autosegmentation (ABAS) software significantly speeds contouring by giving you an advanced starting point. ABAS software approximates the anatomy contours by scanning a library of reference images, applying elements of those forms to a new patient image, and creating a structure set to fit the patient's anatomy.

With ABAS, the contouring process also becomes more:

• Accurate.Multiple phases of refinement produce more accurate results that account for variability between atlas and patient data. Atlas-based segmentation also helps improve contouring consistency across the department
• Flexible.ABAS is fully customizable and compatible with any treatment planning system. It uses standard DICOM file formats and integrates seamlessly into your workflow
• Simple.ABAS is easy to use and configure. It runs in the background, automatically applying contours without user intervention, while you continue to work with your familiar interface
• Efficient.ABAS allows for convenient batch processing, so your workflow isn't interrupted. The software includes a starter library of expert atlases that grows along with your practice

When you can build faster, more accurate treatment plans, you can provide better care for more patients. Let ABAS help.
