Statement of Accuracy
Distance Measurements: Accuracy of distance measurements is the greater of ± 2% or ± 2 mm. All
measurements made by the USB ultrasound system assume an average sound velocity of 1540 m/s in
soft tissue. As the USB ultrasound system can only measure what is displayed on the screen, the
operator must be diligent in obtaining a good image. Measurements should not be used as the sole
determinant of diagnosis and treatment but should always be combined with other clinical data. Various
factors including the scanning technique, familiarity with placement of the calipers, and the tissues
being imaged, affect the image quality and thus the measurement accuracy.
Color Doppler Display: By selecting the CFM mode, the image display will show different colors to
indicate fluid flow toward or away from the probe, and different shades to indicate velocity. The color
information displayed is a qualitative indication of fluid flow and direction. The SP-L01 and GP-C01
probes are able to discriminate between positive and negative low flow rates of 5.5 cm/sec and 3.7
cm/sec respectively at the center of the scale, and show representative lightening of the color displayed
as the flow rates increase, to a maximum scale value of ± 28.0 cm/sec.

WARNING
The experience and diligence of the operator in achieving a quality image are major factors in the
accuracy of distance measurements. The operator must ensure that measurements are made only on
suitable images to achieve accurate measurements.
