JKL is a section of large-scale data that contains databases of medical records, including medical images. This data can help researchers identify patterns in diagnoses and treatments. It is used by hospitals, medical schools, and medical researchers. The 120MB part of the JKL contains patient information such as patient data, medical history, diagnosis, treatments, medications, and lab results. It also includes detailed images from past medical procedures, such as CAT Scans, MRIs, and ultrasound images. This data can be used to assess the effectiveness of treatments and to identify potential risks associated with certain conditions. The data is stored in a secure, HIPAA-compliant environment.
