Abstract

Monitoring bladder volume is a crucial aspect of diagnosing and treating urological disorders. Current methods rely on ultrasound, which, while non-invasive, does not allow for continuous volume measurement. This dissertation focuses on developing a methodology for non-invasive continuous bladder volume monitoring using Electrical Impedance Tomography (EIT). An algorithm for calculating volume from EIT images was proposed, alongside the development of a measurement methodology. The proposed algorithm was clinically tested on 10 subjects. Results show a strong linear correlation between EIT image parameters and bladder volume measured using the BladderScan ultrasound device (up to 0.83). The proposed algorithm for calculating bladder volume from EIT images achieved a correlation of up to 0.45 with measured values. This work confirms the potential of EIT as a non-invasive tool for continuous bladder volume monitoring and introduces a new approach to volume calculation based on reconstructed EIT images from the pelvic region, which could significantly improve diagnosis and care for patients with urinary disorders.
