10 Ways Computers Are Used in Medicine (part 1)

As computers have become mainstream, they have found their way into virtually all aspect of human endeavors and medicine is no exception. They help physicians and medical researchers discover, test and apply medical techniques.

X-rays and CT scans 

X-rays and CT scans use radiation to produce images of a patient's internal structure. X-rays allow for viewing of the internal structure of the patient. CT scanning on the other hand uses computer technology to take several X-ray images that are two-dimensional cross-sections and turn them into a multidimensional picture that doctors use to make diagnosis.


Spectroscopy is the process of irradiating a substance, such as biopsy tissue, and examining the reflected or transmitted radiation patterns. A number of different spectroscopy methods have been developed to measure different energy characteristics. The reflected or transmitted radiation is analyzed by a computer that determines which wavelengths are present or missing. This pattern is then compared to a database of known substances to find a match.

Magnetic Resonance Imaging 

Magnetic Resonance Imagining, known as MRI, is the process of using strong magnetic fields to map the patient's internal structure and activity. MRI is used to produce detailed images of soft tissue in the body without using radiation. The bio-electrical activity in the body is detected by the MRI and fed to a computer that interprets the structure of the are being scanned and presents a three-dimensional presentation of electrical activity in the region, this allows the doctors to search for physical and operational defects.

Patient Monitoring

Patients in a hospital are connected to machines that use vital statistics monitoring software to record the pulse, oxygen levels and the blood pressure of the patients.These computers are programmed to notify the staff if any of these statistics move outside of acceptable ranges.


The computer-controlled surgeries allow doctors to save the lives of patients many miles away.Video networking and real-time vital statistics monitoring allow for safe, precise surgeries that are observed by on-staff doctors or students.
