The purpose of computer-assisted methods is to subserve the diagnosing process through the presentation of information in the images more accessible and more informative form. For this purpose, methods have been developed that take into account the peculiarities of the human visual system to perceive more easily information in color. The article de...

... Title of the Section methods used in lung treatments. The fastest initial assessment method was the use of coloring by tables of conformity ( Figure 2). ...
Context 2
... critical zones are those around bones, the heart, under the diaphragm, especially when the HIS scale in cold colors is applied. In some cases the visualization of the grid structure of the bronchus is being lost -as is the case with HSI in warm and cold colors or it is significantly reduced as is the case with RAINBOW (Figure 2 g) When assessing two-shade scales like HOT and HSI in cold colors, HOT proves much better in displaying lung volume as well as visualizing bronchus grid, which shows that the greater the contrast between the bronchus and the surrounding lung tissue, the better the results. ...
Context 3
... assessing multi-color scales such as the one used in computer tomography (Figure 2 e, g) it is established that an ambiguity appears in the visualization with different colors (Figure 2 e). ...
