{"doi":"10.5281/zenodo.21359298","title":"Design and Implementation of a Portable, High-Speed, Wide-Bandwidth FPGA-Based Electrical Impedance Tomography System","abstract":"This paper describes the design of a small form-factor, low-cost, portable EIT system with a custom analog front end and FPGA controller. Detailed analog and digital design choices are presented and discussed in the context of currently available state-of-the art hardware components and in relation to EIT-driven system requirements. The system is capable of acquisition speeds required for real-time imaging, provides high-SNR measurements over the 100 Hz to 1 MHz frequency range, and has customizable acquisition parameters to allow users to optimize the system for a wide variety of imaging applications. Hardware characterization results demonstrate performance metrics exceeding those of existing small form-factor EIT systems, and multi-frequency imaging results highlight the ability to produce accurate EIT images over the full bandwidth. The development of this highly configurable, high-performing, portable EIT system provides a significant step toward expanding the practical use of multi-application, real-time EIT imaging.","journal":"Zenodo (CERN European Organization for Nuclear Research)","year":2025,"id":588113,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9587,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":534938,"name":"Ethan K.
