ABSTRACT
Computerized Aided Medical Diagnosis system is designed to assist in the medical diagnosis of Pain. The program is based on the assumption that Pain is the principal complaint, and that there are no other dominant complaints or symptoms. The reliability of the program obviously depends on the information supplied by the physician and/or patient. Entering incorrect or misleading information will cause erroneous or unreliable results. The program work on the principle of an expert system. An expert system is software that attempts to reproduce the performance of one or more human experts, most commonly in a specific problem domain, and is a traditional application and/or subfield of artificial intelligence. A wide variety of methods can be used to simulate the performance of the expert however common to most or all are 1) the creation of a so-called “knowledgebase” which uses some knowledge representation formalism to capture the Subject Matter . This program is designed using visual basic and Microsoft access.
ORGANIZATION OF WORK
This project work is primarily designed to give an insight into computerized aided medical diagnosis system used in hospitals.
Chapter one talks about introduction to computerized aided medical diagnosis system on heart disease, study of problem and objectives as well as definition of the scope.
Chapter two comprises the literature review. Chapter three gives the detailed information about the existing (old) system, while chapter four and five deals with the design and implantation of new system.
Chapter six documents the project work, while chapter seven summaries, conclusion and suggestions were made.

INTRODUCTION
Computerized Aided Medical Diagnosis system is used to diagnosis various diseases. In medicine, diagnosis is the process of identifying a medical condition or disease by its signs, symptoms, and from the results of various diagnostic procedures. The conclusion reached through this process is called a diagnosis. The term “diagnostic criteria” designates the combination of signs, symptoms, and test results that allows the doctor to ascertain the diagnosis of the respective disease.
However, it has two distinct dictionary definitions. The first definition is “the recognition of a disease or condition by its outward signs and symptoms, while the second definition is “the analysis of the underlying physiological/biochemical cause(s) of a disease or condition
Typically, a person with abnormal symptoms will consult a physician, who will then obtain a history of the patient‘s illness and examine him for signs of disease. The physician will formulate a hypothesis of likely diagnoses and in many cases will obtain further testing to confirm or clarify the diagnosis before providing treatment. Medical tests commonly performed are measuring blood pressure, checking the pulse rate, listening to the heart with a stethoscope, urine tests, fecal tests, saliva tests, blood tests, medical imaging, electrocardiogram, hydrogen breath test and occasionally biopsy
STATEMENT OF PROBLEM
Owing to:
The difficulties in detecting some sicknesses.
Complex system of human being.
Inability of Doctors to know the actual cause of alignment.
Risk involve in prescribing drugs based on assumption.
The need arise for the development of Computerized aided medical diagnosis system that will enable doctors solve these problems.
PURPOSE OF STUDY
The main purpose of this study is to develop Computerized aided medical diagnosis system that will show the organs of human heart and also gives detail information about them. The program has to show the pictures of both the internal and external organs.
SIGNIFICANCE OF STUDY
With the growth in information technology, the study offers numerous examples in heart diagnosis. Doctors or radiologist do not need to carry a lot of papers in order to check a particular situation but use of heart diagnosis program to do so. Time wasted in attending to parents is reduced to the bare minimum as the software help to facilitate work. Individuals on their own can also buy the software in order to master their body system.
AIMS AND OBJECTIVES
The aims and objectives of this project are listed below:
Increase the awareness and understanding of the value of heart diagnosis system
Achieve efficient and reasonable regulation of heart diagnosis technologies
Interact with appropriate government agencies on reimbursement and technology assessment policies
Improve regulatory harmonization of the global market for heart diagnosis products
Develop and represent industry positions in technical, trade and other issues
All these contributed to show that the computerized aided medical diagnosis system are now been influence by information technology.
SCOPE OF STUDY
This project work is narrowed to the both the internal and external heart organs in human body. The project based more on the pictorial representation of the organs and their functions.
LIMITATION OF STUDY
Owing to the scope of this project work as stated above, this project work is limited to Park lane Hospital Enugu.
It is important to mention here that time was a major constraint in the course of fact finding. It is also wise to mention here that some information we need to work with were not collected because of the unwillingness of the doctors in reviewing some vital information needed for this project work.
ASSUMPTION OF STUDY
One of the major assumptions made in this project work is that manual methods of attending to patients are some times ineffective, time wasting and high level of energy dissipation.
It is also assumed that with the level of development in information technology, there is a serious demand to join this trend of information technology.
It is also assumed that heart diagnosis system will enhance and facilitate medical work.
