What our users are saying

Tens of thousands of treatments have been planned using Limbus Contour. Here’s what clinicians have to say:

• "We explored various auto-contouring solutions and found that Limbus Contour was the only product liked by our dosimetrists. It integrated seamlessly into our existing workflow, representing the closest to 'plug-n-play' medical software that I have encountered. Because the software runs on a local server it greatly simplified the approval process with our hospital's IT department. Limbus Contour has enhanced our productivity and our ability to manage urgent planning requests, making them much more manageable.”

  Greg Salomons, PhD - Medical Physicist & Assistant Professor

  Dept. of Oncology - Cancer Centre of Southeastern Ontario (CCSEO) - Queen’s University

• "Limbus has reduced the time spent contouring in our dosimetrists and physicians by 75% and 55% respectively. We are subsequently starting our IMRT and SBRT patients days earlier than planned while providing dosimetry more time to focus on planning and optimizing. The ease of use, speed and accuracy has made Limbus AI the most indispensable software tool in our clinic.”

  Joe Dise - Landauer Medical Physicist

  Missouri Baptist

• "We were one of the first users of Limbus Contour in Germany and are very happy with it. It is fully integrated in our workflow and saves time in the treatment planning process. With Limbus Contour, auto-contouring of organs at risk as well as nodal regions is very efficient and effective and rarely needs manual adaptations. This young and dynamic company keeps its contouring according to international standards up to date.”

  Dr. Silke Tribius

  Asklepios Clinic - Hamburg, Germany

• "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 Contour 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 excellent support, even though we are very far away and in a completely different time zone."

  Jerome Gastaldo - Chief Physicist

  St. Georges Cancer Center

• "We have been impressed by the quality of the contouring produced by Limbus Contour, its low hardware requirements, speed, customisation and automation options. The application is not reliant on the cloud, which is advantageous for Information Governance and IT security requirements.

  In our dealings with Limbus AI, they have been helpful, supportive and responsive. Informal feedback has seen the speedy development of anatomy models as well as improved functionality. As a result of a successful trial and evaluation, our centre is now using this system in routine clinical practice for all patients."

  Simon Coughlan - Principal Dosimetrist

  Royal Devon and Exeter NHS Foundation Trust

• "We initially started using Limbus Contour within a research project, and have since fully integrated the software into our clinical workflow. We appreciate the flexibility of the software, which does not upload any patient data, and can be easily modified to suit local needs.

  Most importantly, however, I have been impressed by the high quality of the AI-generated contours, which usually require very little manual correction, if any. Limbus Contour has therefore made a big difference for our team, both in terms of the daily workload, as well as the consistency of contouring for various tumor sites."

  Tobias Finazzi - Radiation Oncologist

  Universitätsspital Basel

• "Supported by the know-how of a team of developers who know very well the stakes of modern radiotherapy (radiotherapists and medical physicists), Limbus offers a very efficient auto-contouring solution.

  The software installation is very fast, and does not require very powerful hardware or cloud like other competitors, which is a major asset. The integration of the software is therefore super fast and easy in daily practice."

  Dr. Jean-Baptiste Guy - Radiation Oncologist

  Centre de Radiothérapie Marie Curie Valence

• "I have really appreciated the time saved using Limbus both in CT and in Dosimetry. Most useful from my perspective has been the Head & Neck contouring. I always found the parotids and submandibular 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 & Neck it has saved me 80% of the time it used to take."

  Jim Runkel - Dosimetrist

  BC Cancer

• "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 & Neck patients. As you can see, Limbus Contour makes a big difference on our workload, especially when we are busy."
