Measurement item Functions
FPC (Flow
Pixel Coun-
ter)
*
1
[FPC 15x5mm]
[FPC 15x10mm]
[FPC 30x20mm]
[FPC Rect]
[FPC Free]
[FPC ROI]
Calculates the ratio of the area of a specic area (FPC Box) to the
area of blood-ow signals present within the specic area.
Auto IMT
*
2
[Auto IMT-Near]
Automatically calculates IMT (Intima Media Thickness).
[Auto IMT-Far]
[Manual IMT]
IMT (Intima Media Thickness) measurement that manually mea-
sures thickness at three to ve points.
[Histogram Fix]
Analyzes the gray levels within the square measurement area of
xed size to display a histogram.
[Histogram Free]
Analyzes the gray levels within the rectangular measurement area
of variable size to display a histogram.
[Strain Ratio]
*
3
Calculates the ratio of the average amount of strain in two mea-
surement areas.
[Strain Histogram]
*
3
Analyzes the elasticity in the measurement area and displays a his-
togram.
[E/B Ratio]
*
3
Measures the ratio of Length (E) of two random points in the elas-
tography screen and Length (B) of two random points in screen B.
*
1: Measurements of each FPC item can be obtained only when an image is frozen in Power Doppler- / SCF-mode.
*
2: Use of Auto IMT requires the optional "Auto IMT License".
*
3: You will require the optional "Strain Elastography License" to use the item. Measurement is only enabled when the image is
frozen in Elastography-mode.
