Computers are used extensively in the medical field for hospital administration, patient monitoring, pacemakers, life support systems, drug research and development, imaging technology, remote surgery, telemedicine, nanotechnology, minimally invasive surgery, and DNA sequencing. Specifically, computers allow for remote patient monitoring, pacemakers to regulate heart rhythms, life support systems to monitor critical patients, research into new drugs, advanced imaging like MRI and CT scans, telesurgery using robotics, potential medical nanobots, keyhole surgery assisted by robotics, and decoding DNA to understand genetic diseases.
