The distance between two points is measured.
The length of the traced portion of the curve is
measured.
The angle between two lines is measured in addition
to the distance between two points.
The area/circumference can be measured by the
following methods.
• The approximate value for the tracing along the
external circumference is obtained.
• An ellipse is created along the external
circumference to obtain the approximate value.
• A rectangle is created along the external
circumference to obtain the approximate value.
The volume is measured.
Measures the distances on two perpendicular lines.
Measures the distances between 4 points set along
the same straight line.
Measures the angle formed by two lines.
The left ventricular function can be measured by the
calculation methods listed below.
• Single-plane ellipse method
• Biplane ellipse method
• Bullet method
• Modified Simpson method
• Simpson SP method
• Simpson BP method
• Cube method
• Teichholz method
• Gibson method
The stenosis ratio is measured (% Stenosis).
Measures the volume.
Measures the volume and mass of the prostate.
The intensity of the echo on a line arbitrarily set on an
image can be projected and displayed.
The distribution of the intensity of the B-mode echoes
within the traced area can be displayed graphically.
Evaluates fetal growth.
