How to Calculate the Volume of a Stone | Sciencing

Apr 24, 2017· If you had a perfectly spherical or square stone, calculating the volume would be as easy as measuring its dimensions and crunching a few numbers Unfortunately, stones are not usually a perfect shape, which means any formula calculation will be an estimate at best However, you can use water displacement as a means of calculating the exact ....

Kidney Stone Volume Estimation from Computerized ,

Kidney stone ex vivo To determine the accuracy of the proposed method using real kidney stones 76 stones of common types were evaluated, including 30 uric acid, 3 brushite, 13 cystine, 17 calcium oxalate and 13 hydroxyl or carbonate apatite calculi The reference volume of the stones was measured using the water displacement method...
