Lcd Selections For 2D-Mode Measurements And Calculations - Siemens SONOLINE G50 Instructions For Use Manual

LCD Selections for 2D-Mode Measurements
and Calculations
When the Measurement function is active, you can access these selections
by rotating the FUNCTION SELECT control on the LCD panel to highlight
the 2D tab on the LCD.
Use the system presets to customize the first page of LCD selections for
each exam type. The full list of available selections for 2D-mode is
shown below.
LCD Selection Description
Flow Volume Measures distance or area to calculate an estimate of blood flow volume.
%Stenosis Perform a % stenosis calculation based on the area or diameter of the same vessel.
Volume Perform a volume measurement in either two planes or one plane. Measurement
methods available for calculating a volume in two planes are: LxDxW, Ellipse, and Trace.
Measurement methods available for calculating a volume in one plane are: LxD, Ellipse,
and Disc.
Area Calculates the area using Spline, Cross, Ellipse, or Trace method.
Undo Removes the last measurement label and assigned value from the Measured Results
and report.
A/B Ratio Ratio of measurements. The system calculates the ratios A/B, B/A and (A-B)/A from the
2D-mode measurements: distance, area, or volume.
Angle Determines the angle using two lines you place on the image. The lines must connect
or intersect.
Simple linear measurement between two points.
Distance
A graphical component of a measurement tool. It is a system-generated curve based
Spline
on three measurement points using a spectral waveform.
Cross A measurement tool that utilizes two distances perpendicular to each other.
Ellipse Elliptical measurement. The system determines one diameter using the end points of
the ellipse and calculates the second diameter.
Trace Free hand trace method. Roll the trackball to delineate an area. The system determines
the circumference and area using the trace segments.
2Pl Trace Calculate volume by manually tracing structures in two planes.
1Pl Disk Calculate a one-plane volume using the trackball to trace a structure and then
positioning an axis line to be used for an assumed dimension in a second plane.
2Pl Ellipse Calculate volume by measuring an ellipse in two planes.
2Pl LxDxW Calculate volume by measuring length and depth in one plane and width in a
second plane.
