|October 1, 1986
Summary
We evaluated six methods for bladder volume calculation using ultrasound scans. The best technique utilized numerous scan features, achieving 0.87 accuracy and +/- 9% repeatability for volumes over 150 ml.
Area of Science:
- Medical Imaging
- Diagnostic Ultrasound
- Urology
Background:
- Accurate bladder volume measurement is crucial for clinical assessment.
- Current methods for estimating bladder volume may have limitations.
Purpose of the Study:
- To compare the accuracy and repeatability of six distinct methods for calculating bladder volume from ultrasonic cross-sectional scans.
Main Methods:
- Six different computational techniques were applied to ultrasonic cross-sectional scans.
- Methods varied in the number of features extracted from the ultrasound images.
Main Results:
- The method incorporating the most features from the scans demonstrated superior performance.
- For bladder volumes exceeding 150 ml, an accuracy of 0.87 was achieved.
- Repeatability was found to be within +/- 9% (standard deviation) for the optimal method.
Conclusions:
- Utilizing a comprehensive set of features from ultrasonic scans significantly improves bladder volume calculation accuracy.
- The developed technique offers a reliable and repeatable method for non-invasive bladder volume assessment.
