Catharina uses AI to make cancer treatment plans

The hospital writes this on its website† This puts an end to the manual work involved in making precise radiation plans and drawing individual patients’ organs onto CT images. From this spring, the Radiotherapy Department of the Catherina Hospital will partly switch to AI-generated plans, and soon with the registration of organs. It will soon save radiotherapists and lab technicians hours of work per patient and will ensure greater consistency.

Datasets

The organs are drawn very precisely on CT images or MRI images. In a flight simulator it is then simulated how one wants to irradiate: from which side and with what intensity, so that as much radiation as possible enters the tumor and as little as possible around it. The simulator contains a model of the treatment devices plus images of the anatomy of the individual patient. These are currently processed by a laboratory technician in a treatment plan, but that can be automated with AI. Data sets with hundreds of patient treatment plans are used for this. The computer model went live this month. The model is also ready for automatic drawing in of the organs and glandular areas and a clinical pilot is now underway.
