Abstract

Med-Aid AI Contour is a software applying artificial intelligence (AI) to contour organs at risk (OAR) base on CT scans. This is a tool to assist oncologists on contouring OAR to reduce time and improve the quality with more accurate quality.

Purpose: Evaluate the quality of AI Contour and the software’s self-study and self-improve ability when the amount of input data is increasing.

Materials and Methods: Cases of cancer in different locations include: Head, Chest and Abdominal are used as input data for AI Contour to self-study, and then evaluate contour results based on 60 cases with contour samples reviewed by doctors. Implement statistics of results when input data for Abdominal increasing from 125 up to 716 patients.

Results: The latest version of AI Contour showed results over 80% contours acceptable. Specifically: the Head area 83.02%, the Chest area 82.69%, the Abdominal/Pelvic area 82.41%.

Discussion: AI Contour gives gradual better results when input data increases. For example Abdominal area, the acceptable rate increased from 52.02% (with the input was 125 patients) to 81.22% (with the input was 716 patients).
