Deep learning-based autocontouring

Organs-at-risk contouring in Radiation Therapy for various clinical environments

Accurate contouring of organs-at-risk (OAR) is one of the major bottlenecks of Radiation Therapy planning, but still the necessary first step in the process. Therefore, the increase in the number of patients puts significant pressure on radiotherapy staff responsible for consistent OAR contouring results. Advances in technology and artificial intelligence can help automate repetitive tasks such as OAR contouring, thus reduce workload, and standardize key CT simulation steps.

Speak to an expert and learn more about automated contouring solutions for various radiation therapy clinical environments.

Clinical Use

Why AI-based autocontouring?

Our deep-learning based autocontouring solutions enable precise organs-at-risk contouring. They provide consistent results as a starting point for treatment: 

>95% of the contouring results are clinically usable or require minor edits1.

Challenges of manual organs-at-risk contouring

Organs-at-risk (OAR) contouring creates a substantial amount of effort and is a major source of variability in RT planning. Modern treatment techniques rely on consistent OAR contours as a starting point. The time spent on OAR contouring keeps staff from focusing on clinical tasks like devising an optimal treatment plan.

The quality of autocontouring depends on the quality of the CT images

  • Suboptimal image quality leads to suboptimal autocontouring2,3 that needs to be modified or re-done
  • Radiation oncology professionals have no consistent starting point for RT planning

Autocontouring solutions for various clinical environments

AI-based autocontouring: Efficiency and automation throughout the radiation therapy planning process.

How can we accelarate the path to treatment?

With AI-based autocontouring and EclipseTM we enable you to reach efficiency and automation throughout the planning process. The contouring of the organs at risk is done automatically with the support of deep learning algorithms. It may reduce unwarranted variations with high-quality contours that approach the level of consensus-based contours.8
