Computers are widely used in hospitals to help doctors in diagnosis,getting information on patients,diseases,treatments,drugs etc.They are also used in administration and in keeping patient records.Doctors can get information from distant data banks and expert systems.
Many medical databases are being developed.They contain information on diseases and treatment. Doctors are taking help of expert systems in the diagnosis and treatment of a patient.An expert system is a program based on the expert knowledge of specialists.It is a diagnostic tool for doctors.The doctors have to supply the detailed information such as symptoms,medical history,test results etc.This information is processed by the computer ans a diagnosis is made by the expert system.At present the expert systems are helping doctors;they do not substitute doctors.They are currently useful primarily in reminding doctors; they do not substitute doctors.They are currently useful primarily in reminding doctors of diagnosis and treatment that should be considered.The databases in the expert system must be constantly checked and updated.Some more details are given later on in this chapter.
many devices take images and diagnose diseases.Such devices use computers process huge amount of data collected by the scanners associated with such devices.Examples are: Computerized Axial Tomography (CAT),positron Emission Tomography (PET),Magnetic Resonance Imaging (MRI) etc. These devices take pictures of brain and help in diagnosis of various kinds of diseases.These machines are at present very expensive.
Computers are also used in pathological tests.Programs have been developed to monitor various pathological processes,record data and analyze results.From a single sample of blood computer can test hemoglobin, hematocrit ,glucose, BUN,creating,total CO2,chloride,sodium,potassium,calcium,phosphorous,uric acid,albumin,protien,globulin,A/C ratio,cholestrol,triglycerides,bilirubin phosphate,white and red blood cell count etc. Computer controller monitoring of tests increase speed,and give accurate and reliable results.
