cell plasmin can be seen more clearly; 
3.1.3 The similar density of the Chondriosome in 
the black and white imagery were in 
different colors. This phenomenon meant that 
when a certain plasmin or an organ within a 
cell had got some small changes which was 
not enough to be distinguished by the 
density differences in the black and white 
imagery, but after false-coloring it is 
possible to reveal the difference with 
different colors in the false—color imagery. 
Therefore, this technology can be an useful 
referential means for detecting and 
diagnosing some diseases. 
3.2  False-coloring of a S EM Imagery 
This imagery was offered by the same organization 
mentioned above. The target was a cancer cell of a 
human stomach. After false-coloring we have got the 
following results: 
3.2.1 Abundant false-colors were obtained for 
better interpretation; 
3.2.2 The outline of the cell was clearer; 
3.2.3 The surface of the cell with  radiated 
structure was much clearer; 
3.2.4 The lesion lines in the cell surface can be 
seen more clearly. 
3.3  False-coloring of a Optical Microscope Imagery 
This imagery was offered by the Prevention and 
Protection department in the Academy of Medical 
Science of Hubei province, China. The target was a 
micro nucleus of a cell of the human Lymphatic 
Gland. After false-coloring we have got the 
following results: 
3.3.1 It is much clearer that the colors of the 
main and micro nucleus drifted in the 
plasmin of the cell were identical; 
3.3.2 The boundary lines of the main and micro 
nucleus in the cell were much clearer; 
3.3.3 These results can confirm that we can enhance 
the interpretation ability for recognizing 
the structure of the micro nucleus in the 
human Lymphatic cell to a certain extent. 
3.4 The same as in 3.3 
The target was a nucleus Hernia in the human 
Lymphatic cell. After false-coloring we have got the 
folloewing results: 
3.4.1 The false-color imagery has shown an another 
metamorphosis of a cell nucleus — nucleus 
Hernia clearly; 
3.4.2 It was much clearer that the formation of 
the nucleus Hernia was due to that the 
partial plasmin of the cell nucleus went 
outward from the membrane of the cell 
nucleus; 
3.4.8 These results have confirmed us that the 
false-color imagery had more abundant color 
series; the information required could be 
emphasized and it is quite helpful for 
recognizing the formation of the micro 
nucleus in the human Lymphatic cells. 
3.5  False-coloring of a Ultrasonoscope Imagery 
This imagery was offered by the Tumour Research 
Institute in the Tumour Hospital of Hubei Province, 
Wuhan, China. The target was a abdominal cavity of a 
human. After false—coloring we have got the 
following results: 
3.5.1 The cavity of the intestines could be seen 
more clearly; 
3.5.2 The substance in the intestines was 
dislplayed more clearly; 
3.5.3 The liver and the various layers of the 
belly walls were also displayed clearly. 
3.6 The same as in 3.8 
The target was a Myoma of a woman's Uterus. This has 
been proved by thé clinical treatment in their 
hospital. After false-coloring we have got the 
following results: 
3.6.1 We can distinguish the normal muscle of the 
uterus by the dark brown color; 
3.6.2 We can distinguish the fibre tissue or small 
dead parts and glass-like focus by green or 
blue green: 
3.6.3 We can distinguish the muscle fibre tissue 
in the edge of the Myoma by red color; 
3.6.4 We can distinguish the center part of the 
Myoma by green; 
3.6.5 These results has confirmed us that the 
cavity of the intestines; the different 
characteristic substances and the difference 
between the muscular and fibrous tissues in 
the Myoma of the Uterus can be easily 
distinguished. 
All of these can show us that the potential 
capabilities of this technology are valuable. 
3.7  False-coloring of a C T. Imagery 
This imagery was offered by the Radiation department 
in the Tong Ji Subordinate Hospital of the Tong Ji 
Medical University of Wuhan. Wuhan, China. The 
target was a Pituitary Adenoma of a huaman Brain. 
This has been proved by the clinical treatment in 
their hospital. After false-coloring we have got the 
following results: 
3.7.1 We can easily distinguish the grey matter 
and white matter of a human brain: 
3.7.2 We can easily distinguish the structure of 
the Ventricle walls of the brain; 
(9 
.7.3 It is possible to distinguish between the 
Ventricle walls and the Cerebrospinal fluid; 
3.7.4 It is easier to distinguish the differences 
among the calcific ring around the Pituitary 
Adenoma, Adenoma tissue itself,the Ventricle 
and the surrounding brain tissues. 
4. CONCLUSIONS 
The advantages of the Optical Density Encoding 
Techniques have been briefly introduced. However, 
there are some inherent disadvantages in the single 
black and white imagery, such as:
