Automatic Contouring for Radiation Therapy

• Clinically validated deep learning segmentation for radiotherapy

  Fast

  Scans are contoured in seconds using preferred structure set templates from planning.

  Automated

  Contours generated automatically and sent immediately to treatment planning system after each scan. Configure once, implement in workflow forever.

  Turnkey

  Extensive library of clinically validated anatomical structures ready for immediate use out of the box.

What our users are saying

Thousands of treatments have been planned using Limbus Contour - Here’s what clinicians have to say:

• "We aim to deliver radiotherapy treatments in the shortest timeframe possible. At the same time, radiotherapy is evolving rapidly with Adaptive treatment, Hypofractionation and SABR which require very accurate structure definition and thus thinner slices. This increases the required time for contouring, placing more pressure on staffing resources and workflow. AI based algorithms offer great potential to reduce this pressure.

  From our initial investigation, Limbus Contours is providing excellent results for multiple sites. For example, within minutes we can create the main contours required for a prostate treatment. After reviewing numerous cases we have found that the contours produced required very minimal editing. This allows us to very significantly decrease the amount of time required before starting the planning stage.

  The software is very easy to setup and straightforward to use. We have also found the Limbus team extremely responsive to our requests with an excellent support, even though we are very far away and in a completely different time zone."

  personJerome Gastaldo - Chief Physicist

• "Limbus Contour is saving me at least 45 -60 minutes for pelvis patients, about 45-60 minutes for SRT Brain patients, about 30 minutes for Lt Breast 4-field patients, about 20 minutes for thorax patients, and at least 30 minutes for Head and Neck patients. As you can see, Limbus Contour makes a big difference on our workload, especially when we are busy."

  personRainbow Yu - Radiation Therapist

• "I have really appreciated the time saved using Limbus both in CT and in Dosimetry. Most useful from my perspective has been the head and neck contouring. I always found the parotids and submanibular glands very hard to delineate. But now with Limbus Contour it helps focus your attention and lets you follow the structure better and usually only small changes need to be made. From a pure work standpoint, the femoral heads are so tedious to contour and having them done is fantastic. The more structures Limbus Contour can do the more time we can focus on doing the dosimetry. I would suggest that for head and neck it has saved me 80% of the time it used to take."

  personJim Runkel - Dosimetrist

• "As a center we have really loved using Limbus and have become heavily dependent on it. It has been a great technology that we really value that allows us to spend more time scanning patients and lets us still complete contouring efficiently and expertly."
