{"doi":"10.1109/uffc-js60046.2024.10794018","title":"TranSpeed: Transformer-based Generative Adversarial Network for Speed-of-sound Reconstruction in Pulse-echo Mode","abstract":"Longitudinal speed of sound (SoS) serves as a valuable biomarker for tissue characterization and facilitates phase aberration correction to enhance ultrasound image quality. While deep learning (DL) methods have shown promise for SoS reconstruction, traditional convolutional neural networks (CNNs) have limitations in capturing long-range dependencies. This study introduces TranSpeed, a transformer-based generative adversarial network designed to reconstruct complex SoS distributions with a large receptive field. TranSpeed is designed to capture long-range dependencies by patchifying input phase-shift maps and incorporating positional encoding. A model was trained on numerical simulation samples and evaluated on an open-access breast ultrasound computed tomography (USCT) dataset. The results demonstrated the feasibility of TranSpeed in reconstructing complex SoS patterns.","journal":null,"year":2024,"id":486486,"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":4,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9582,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1330724,"name":"Yuanbin Zhu","orcid":null,"position":1,"is_corresponding":false},{"id":855445,"name":"Jingyi Zuo","orcid":null,"position":2,"is_corresponding":false},{"id":1330725,"name":"Md Rizwanul Kabir","orcid":null,"position":3,"is_corresponding":false},{"id":259399,"name":"Aiguo Han","orcid":"0000-0001-7606-9221","position":4,"is_corresponding":false},{"id":1330341,"name":"Haotian Chen","orcid":"0009-0008-5035-8672","position":0,"is_corresponding":true}],"reference_count":22,"raw_metadata":null,"created_at":"2026-07-19T02:08:01.404471Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
