Malignant Tumor Location

Computers and atomic physics are used to quickly and early locate the malignant tumor when treatment is most effective. This method depends on the accumulation of some isotopes in malignant tumors more

than in healthy tissues surrounding the tumor. If these isotopes enter the body, the tumor becomes more radioactive than the surrounding tissues and organs. The tumor can then be located using an imaging machine that works with atomic radiation, and contains a number of detectors that are affected by the radiation used. This imaging machine focuses on the spot where the tumor is suspected to be present, so the detectors directly above the tumor receive more radiation than those above healthy tissues. These detectors emit electrical signals proportional to the radiation they receive, and these signals are sent to an analog or digital computer for analysis. A digital computer stores this information and displays it on a color television screen that clearly shows the location of the malignant tumor.

Diagnosis of diseases

The computer is used in diagnosing diseases, as a tool that helps the doctor in this field and does not replace him. The doctor can extract a lot of diagnostic information from seeing the patient and talking to him, while the computer must reach its diagnostic conclusions based on the yes or no answer to the questions it asks. Since some symptoms may not appear in a disease in which they are supposed to appear, while some symptoms that the patient may complain of may have nothing to do with his main disease, the computer's ability to make a reliable diagnosis is still very limited, and there is no alternative but to rely on the doctor's experience and good judgment.

However, the computer may greatly help the doctor in other aspects. The doctor must review medical books and journals from time to time to retrieve any information he may have forgotten or to see what is new in his field of specialization. The computer can be used to store a lot of information and classify it for the doctor to refer to when needed. Intuition can also help the doctor with an approach to follow in his attempt to diagnose a disease. (The program path differs according to the context of the program for diagnosing the symptoms that the patient complains of. In this field, the computer is considered a tool that helps the doctor diagnose the disease, and the doctor may ignore the computer completely at times, relying on his own estimates.)
