A computer simulation is a special type of computer model, which used to train peoples how to deal with situations that are too difficult, expensive or dangerous to recreate and practice for real. For example a flight simulation, which is used to train, pilots how to deal with situation that would be expensive and dangerous to practice using a real aircraft. A flight simulator consists of a working replica of the flight deck of an airplane.
Medical
The computers are commonly used in some area of medical fields such as laboratories, researches, scanning, monitoring, pharmacy etc., which are helping the doctor to diagnose an illness.
- Patient Monitoring: Computers are used in hospitals to monitoring critically ill patients in intensive care units. The patients have sensors attached to them, which detect changes in heart rate, pulse rate, blood pressure, breathing and brain activity. If any readings dislocate or reached misbalancing level, the computer activates an alarming device to create sound and alerts the medical staff. The data is also logged and used to analyze the changes in a patient’s condition over a period of time.
- Patient Records: Computerized databases are used to store information about patients, doctors, medicines and other chemicals and equipments. Storing information in proper order to provide the convenient way of arrangements for hospital staff. It is make easy to organize records than paper-based records that are not constantly following patients around the hospital. For example if a patient is admitted in one ward but being seen by a consultant and receiving treatment in other parts of the hospital; their details can be viewed and updated at any terminal in the hospital’s LAN network.
The computerized database are used to help match patients who are waiting for organ transplants such as new kidney, liver or heart with suitable organs from donors.
Diagnosis
It will come as no surprise that hospitals and clinics use computers to keep records and generate invoices. One common use of electromagnetic rays through a patient’s body and sensors detect that how much patient’s body have affected to any type of cancer. Actually the body scanner helps the doctor to treat any type of tumors or cancers. For example, the CAT scanner passes rays over the patient; it displays an images that enables physicians to look beneath the patient’s skin. As the scanner passes over the patient, it displays an image of bone and tissue structure on a computer screen(see figure 4.7).
Computerized axial topography(CAT) still uses X-rays to see inside the body. But instead of using a single beam, a CAT scanner takes many X-rays around the body.see Fig 4.7
