Medical data annotation is essential for enhancing healthcare outcomes through the systematic annotation of various data types, including images, videos, and text. This includes medical image annotation, which focuses on the segmentation and labeling of X-rays, CT scans, and MRIs to identify critical features within the images. Video annotation is also performed to monitor patient movements and behaviors, which is crucial for assessing recovery progress. Additionally, text annotation is used to extract vital information from medical reports and prescriptions, enabling a more comprehensive analysis of patient health records.
