In every industry and in most businesses computers have become a simple cost saving solution. Hospitals are no exception to this fact, and actually the hardware used in hospitals such as Presbyterian Hospital, are highly advanced suffocated machines tailored to the needs of employees and patients. Of course not all hospitals operate using the same equipment or computer system. Outside of the normal PC workstations and the peripherals that most all businesses use, hospital computer hardware also includes a lot of imaging and scanning devices. Taking the time to just consider what it takes to run a large facility such as Presbyterian Hospital, you could imagine that there are tons of servers, monitoring equipment, and workstations. Medical imaging is digital and is aided by computers; sometimes even the pharmacy dispensary is computer automated.
Computer systems are designed to process information. There are three phases in processing information, and each phase uses its own device. Hospitals use computers to do a large number of things such as make appointments, create billing information, and lookup pharmacy information. A simple hospital operation performed daily is reading x-rays and ultrasounds. This process uses input devices, storage devices, and output devices.
The first phase is the input phase. This is where information is entered into the computer system through an input device. An input device is any peripheral used to deliver data to a computer system. Some familiar input devices are the keyboard, mouse, scanner, microphone, and web camera. The input device used in obtaining an x-ray is called a computerize tomography (or CT). A CT is a scanning device that takes an electromagnetic image of the inside of a human’s body and sends it to the computer system. After scanned data is inputted into the computer system, it is processed and some modifications are done by the central processing unit.
While the inputted data is being modified, the scanned...
