Abstract
A mathematical model for calculating elliptical volumes of fluid contents by means of ultrasound is described. The suggested formula is: V = ABCπ/6. The model was investigated on the apparatus which was especially constructed for the purpose. Because of the technical characteristics of the apparatus the measuring range was limited to the volumes from 50 to 112 ml. The results of 32 measurements on the model showed a very high correlation between the calculated and real values (r = 0.979), and a high accuracy of evaluation (the lowest difference between the calculated and real values was 0.1 and the highest 10.0 ml). This opens a possibility of applying the model in medical diagnostic practice.
