The paper presents the design, development, and optimization of a hybrid mobile tomograph integrating Ultrasound Tomography (UST) and Electrical Impedance Tomography (EIT) for long-term, non-invasive monitoring of the lower urinary tract. The proposed solution is characterized by the integration of miniaturized and energy-efficient electronic modules within a wearable system, facilitating wireless communication and real-time data acquisition. The final prototype incorporates advanced power management, customized sensor systems, and the integration of UST beamforming and EIT signal acquisition. Comprehensive electromagnetic compatibility (EMC) and electrostatic discharge (ESD) tests were conducted in compliance with medical device standards (PN-EN 60601-1-2), thereby confirming the tomograph's suitability for clinical and home healthcare environments. The findings indicate that the hybrid approach enhances diagnostic imaging while ensuring safety, comfort, and mobility for patients, particularly in pediatric applications. The solution contributes to the advancement of smart medical diagnostic tools in biomedical engineering.
