Ct scan segmentation
WebAug 4, 2024 · Segmentation masks are the most time-consuming to obtain because they must be drawn manually on each slice; thus, segmentation studies typically use on the order of 100 – 1,000 CT scans. Model Convolutional neural networks are the most popular machine learning model used on CT data. For a 5-minute intro to CNNs, see this article.
