Based on x-ray and optical transport simulation, we have developed an analytical model to predict the response of the measurement chain (collimator-scintillator-photodiode) in CT detector. We present the resulting effects of misalignments of the collimator array to detector array in the imaging chain through the simulation of beam hardening (water equivalent material and/or Bone) and light output using 120 kVp bremsstrahlung x-ray spectrum from a tungsten target anode source.","is_dataset_classified":null,"base_score":0.0,"endowment":0.0,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19162232","pmcid":null,"openalex_id":"https://openalex.org/W2026357255","authors":[],"funders":[],"total_grants":0,"fwci":0.0,"citation_percentile":0.17289615,"influential_citations":0,"citation_trend":[],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://doi.org/10.1117/12.524044","host_type":"journal"}],"fields_of_study":["Advanced X-ray and CT Imaging","Medical Imaging Techniques and Applications","Radiation Dose and Imaging"],"mesh_terms":[],"keywords":["Scintillator","Collimator","Detector","Optics","Photodiode","Scintillation","Physics","Monte Carlo method"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Clean water and sanitation"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-10T03:00:13.574895Z","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":[]}
