Simulation and Experimental Study of Bladder Filling Degree based on a High-Fidelity 3D Model of The Lower Abdomen Built by CT Image
Pages 1 - 5
Abstract
In this work, the auxiliary bladder filling degree perception function is established for patients with impaired bladder sensory function to help patients improve their quality of life. This study intends to build a 3D finite element model of the lower abdomen of the human body by modeling CT images. The simulation experiments based on the three-dimensional finite element model aim to determine the placement of the double electrodes and to explore the effect of different signal frequencies on the sensitivity of bladder filling degree. The results of the simulation experiments were then verified by recording the changes in electrical impedance during the natural bladder filling process of one healthy volunteer after 550ml of water was drunk. The electrical impedance measured in the human experiments has a negative correlation with the bladder filling degree in time accumulation, which is consistent with the simulation experiments results. The results of this study verify the possibility of finding the best electrode placement point in the lower abdomen of the human body through simulation experiments and human experiments. And The sensitivity of measuring bladder filling degree is better at the frequency of 1-10Khz.
