Chapter 8 Measurements and Calculations

Measurement Accuracy

Measurement values can vary depending on the nature of the ultrasound wave, the body’s response

to ultrasound waves, the measurement tools, algorithms, product settings, probe type, and the actions

performed by the user.

Before using this product, make sure to read and understand the following information regarding the

causes of measurement errors, and measurement optimization.

Causes of Measurement Errors

 Image Resolution

The resolution of an ultrasound image may be limited by spatial causes.

X

Errors caused by signal range may be minimized by adjusting the focus settings. Optimizing the

focus settings increases the resolution of the measurement area.

X

In general, the lateral resolution is lower than the axial resolution. Therefore, measurements

should be performed along the axis of the ultrasound beam to obtain accurate values.

X

Gain has a direct impact on the resolution. Gain can be adjusted by using the Gain button for

each mode.

X

In general, increasing the frequency of ultrasound enhances resolution.

 Pixel Size

X

This product’s ultrasound images consist of pixels.

X

Since a single pixel represents the basic unit of an image, a measurement error may result in the

displacement of approximately ±1 pixel when compared to the original image size.

X

However, this error becomes signicant only when a narrow area in an image is measured.
