Analysis of three main error sources in traditional bladder volume formula and development of a computer bladder volume calculation program

This study analyzed three main sources of error in bladder volume calculation by traditional ultrasound formula, which is most commonly used clinic and built into ultrasonic diagnostic apparatus. In order to solve these errors, we changed the formula calculate based on axis section area, corrected this according actual clinical data obtain a new called modified ellipsoidal trend formula. can easily manually during examination bladder. Based OpenCV function applied build program for calculating through two images The method total number pixels contour image program, convert using algorithm be implanted Ultrasonic apparatus or workstation replace study, 122 cases were test accuracy results showed that was more accurate than
