{"doi":"10.36227/techrxiv.23735499","title":"DOI- and TOF-capable PET array detector using double-ended light readout and stripline-based row and column electronic readout","abstract":"<p>We investigate an economic readout for depth-of-interaction (DOI) and time-of-flight capable PET detector that consists of an N×N array of crystals whose light outputs at the front- and back-end surfaces are detected by using silicon photomultipliers (SiPM). The N×N SiPMs at the front-end (back-end) of the detector are read by a stripline configured to support discrimination of the row (column) position of the signal-producing crystal, producing only four outputs for the detector. To evaluate this design, we built 4×4 and 8×8 detector modules (DM) by using 3.0×3.0×20 mm3 lutetium-yttrium oxyorthosilicates. The outputs were sampled at 2 GHz and processed offline. For both DMs, crystal discrimination was successful. For the 4×4 (8×8) DM, we obtained a crystal-level energy resolution ranging from 11.3% to 19.3% with an average of 14.1% (9.5% to 21.6% with an average of 13.9%), an average DOI resolution of 2.5 mm (3.1 mm), and a best coincidence resolving time (CRT), measured in coincidence with a single-pixel reference detector with a 302 ps CRT, of 391 ps (603 ps). The CRT deteriorated with the (8×8) DM possibly due to intercrystal scattering.</p>","journal":null,"year":2023,"id":396921,"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":2,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9561,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":588104,"name":"Chien-Min Kao","orcid":"0000-0002-8785-5225","position":1,"is_corresponding":false},{"id":588513,"name":"Yuexuan Hua","orcid":null,"position":2,"is_corresponding":false},{"id":1172571,"name":"Linfeng Liu","orcid":"0000-0002-0824-6203","position":3,"is_corresponding":false},{"id":1172572,"name":"Xiaoyu Zhang","orcid":"0009-0008-8235-3091","position":4,"is_corresponding":false},{"id":588102,"name":"Heejong Kim","orcid":"0000-0002-8229-0720","position":5,"is_corresponding":false},{"id":882471,"name":"Woon‐Seng Choong","orcid":"0000-0003-3372-2803","position":6,"is_corresponding":false},{"id":588103,"name":"Qingguo Xie","orcid":"0000-0001-5353-2201","position":7,"is_corresponding":false},{"id":869623,"name":"Fei Wang","orcid":"0000-0003-3462-8472","position":0,"is_corresponding":true}],"reference_count":37,"raw_metadata":null,"created_at":"2026-07-19T01:19:35.497854Z","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":[]}
