ACCURACY SPECIFICATIONS
Table 18. Accuracy Specifications
SPECIFICATION DESCRIPTION
Bladder volume range 0 to 999 mL
Volume accuracy
greater than 100mL ±7.5%
0–100mL ±7.5mL
The following examples show how the accuracy ranges shown in Table 18 may affect reported volume
measurements.
• If the measurement is greater than 100mL, the accuracy range is ±7.5% and is calculated asfollows:
240mL×7.5% =18mL
240 ±18mL = 222–258mL
• If the measurement is 0–100mL, the accuracy range is ±7.5mL and is calculated as follows:
80 mL ±7.5mL = 73–88mL (rounded to the nearest whole number)
The accuracy specifications assume the system is being used according to the instructions provided by
Verathon while scanning a tissue‑equivalent phantom.
While the upper threshold of the accuracy range is 999 mL, the system is capable of detecting and displaying
bladder volumes above 999 mL. Verathon cannot guarantee the accuracy of measurements outside of the
stated specifications.
