Modern healthcare would become void without these wonderful machines. The hospitals require computers in all stages of treatment right from diagnosis to surgery. The advanced scans such as MRI and CT (Computerized Axial Tomography) scans help you detect life-threatening conditions. The entire department of radiology is dependent on these electronic machines. Then we have fitness trackers and ECG bands that could warn you of imminent heart ailments and strokes. Our doctors perform robotic surgeries by looking at a monitor. We are moving towards a time when we can swallow the computing devices in the form of a pill to get accurate images of the internal organs like the intestines.
