At present, the four factors leading to the highest
death rates of humanity are encephalemia, cancers, myocardial
infarct, and traffic accidents.
To each of the four factors,

unique merit in diagnosing the victim's hidden traumas

makes it possible to observe, directly from the external side,
the functional status, size and location of the internal organs.
This possesses a unique value to the diagnosis of some
pathological development caused by occupation of organs.
example, the static display of nuclear medicine can diagnose
the pathological change concerning occupation in the case of i
liver cancer, with the rate of coincidence over 80-85% usually.
At present, the most advanced nuclear medical visual-display
technology, after undergoing the computer image reproduction,
has progressed from the static, qualitative and 2-dimensional
level to the kinetic, quantitative and 3-dimensional level.
For instance, the various isotopic laminal display (CT)
techniques have rendered it possible to observe the kinetic
growth or declining of the isotopic tracing agents in the
particular parts inside the human body, thus giving a
penetrating representation of the function and metabolism
of the organism.
This unique point enjoys tremendous clinical
value, because in the course of the emergence and development
of a disease, the functional change of the organism is usually
earlier than the formal and structural changes. In particular,
