"Mobile ward round system" uses mobile devices to be mobile at any time, combined with HIS, NIS, PACS, and LIS, to improve the time-consuming problem of accessing paper medical records. This allows doctors to accurately monitor patients' conditions through mobile devices during rounds, and explain examination results and subsequent medical treatment to patients, including CT scan images. It can also be used as a tool for doctors to access patient information when giving verbal medical orders outside of the hospital.
