  America has one of the best medical systems in the world. The medical
treatment care options offered by the medical system make it sophisticated.
However, many American patients are not receiving health care on a regular
basis, and at the same time, they cannot afford it. Also, the current medical
system has many flaws such as high medical treatment costs and lack of doctors
to accommodate many patients. This paper presents the principles of medical
artificial intelligence called the knowledge based system. Doctors can remotely
check and monitor their patients health data, medical history, how and what
medical tests were done, and the lab results. The patients have access to
detailed health information online and do not need to make an appointment with
doctors to check their health on a daily basis. One doctor can check many
patients simultaneously online (when medical centers are understaffed) and do
not need to spend a lot of time with patients. Thus, doctors save more money
for patients, because patients will no longer be transporting to medical
centers to receive routine health check-ups. Patients do not need to overpay
for their insurance because they will have access to the knowledge-based
system, and the system will save the patients money to have their health
checked and reduce the number of unnecessary medical exams. This paper
undertakes a brief overview of research work done in a knowledge based system
rule based expert systems in the field of medical practices.
