THE DESIGN AND IMPLEMENTATION OF A COMPUTER AIDED SYSTEM FOR MEDICAL DIAGNOSIS AND TREATMENT OF ILLNESS A CASE STUDY OF UNTH ENUGU

ABSTRACT

Technological trend in recent time’s nit nesses an appreciable decrease in hardware cost, implementation in microchip technology and a boost in the use of micro – computer’s in all ere as of human life. The health industry is among the sectors formed by the innovation, effected by the multiplicity of flexible, easy to use and interactive software packages tailor to meet the handicaps of the medical profession and to provide a relief of the human effort involved in the practice. This project report tend to describe computer base system of medical diagnosis the chemical feature of some common illness and their different treatment are distinguish able by the use of oral interview. This system interrogates a patient using the general principle and technology of chemical examination. With details of inference to the underlying diseases and recommendations for treatment. This study course only the diagnosis of such illness as feverish conditions that do not involve the service of a medical laboratory test such as malaria parasite, ealmoneilosis infections (typhoid) hepatitis upper respiratory track infections (URTI) and septicemia (infection of the blood with bacteria). The features and working principles of a typical expert – system are allied in the design and implementation of the system is a help to draw conclusion from the knowledge based. The information were extracted from different experts in medical profession. The analysis of the existing system was taken into consideration before the development of the software in other to ensure prompt and timely information and recommend treatment for the patient. The new system is very interactive and flexible and is capable of solving any medical diagnosis problem within the scope. A software was developed with Q basic as the language of the program is based on flexibility. Since the ultimate aim of this project as to design and diagnosis support system of artificial inteligate (A.I) that mimic the expertise doctor in clinical diagnosis.

ORGANIZATION OF WORK

This project work is divided into seven chapters.

Chapter one is a survey of the health industry, the medical profession with a brief exposure of their inherent handicaps that calls for allevation or present the problem that triggered the design of the system and the aims and objectives of the study.

In chapter two the researcher took a critical and conceive look on the literature review of the system and other work works that are lifted by other people in the medical field.

In chapter three traced the description and analysis of the existing system. The method of data collection, the problems of the existing system and justification for new system.

Chapter four is a details design of the computer aided system for diagnosis and treatment of illness stating its system requirement, the file design and the input / output specifications with appropriate illustration. The procedure and system flow chart.

Chapter five moved for the effective implementation of the designed system where the programs and pseudo code were discussed.

Chapter six talked about the appropriate documentation of the system and the user’s guide for efficiency.

Chapter seven summarizes the entire work as conclusion and fare recommendation and areas of further studies, moreso, the authors whose book were reference in this work are included in the references.
