3.4.3 Core method
The Core method is an analysis method to calculate values such as CD (cell density)
by extracting the outline of the cell referring to the center of the cell entered by the
physician
a) Switching to Core method
1㸧 Touch the “Method” button (1) on the analysis screen to open the
Method screen (Fig. 2).
(Fig. 1)
(Fig. 2)
2㸧 Select the “Core” button (2). Touch the “OK” button to open the Point
Edit (Core Method) screen (Fig. 3).
b) Editing point
ڦ
Be sure to observe the following precautions when specifying dots in the
Core method. Incorrect results may be displayed.
ڦ
The number of points should be 50 or more. The recommended number of
points is 100 or more.
ڦ
Point to the center of the cell as much as possible. The accuracy of analysis
results lowers as the point position deviates from the center.
ڦ
Determine the range for pointing in advance and then specify the point in all
cells included in the determined range. If cells are not specified, the CD (cell
density) will be calculated as smaller than the actual value. It is
recommended to specify cells from the top center area to bottom center area,
and then the surrounding cells clockwise in order to specify all cells.
