Three studies form its foundation: (1) an ex vivo evaluation of coronary artery calcium scoring reproducibility in photon-counting CT, demonstrating that thin-slice reconstruction and z-start averaging mitigate partial volume effects; (2) an ultra-low-dose pediatric kidney stone analysis using spectral tin filtration and quantum iterative reconstruction, showing that sub-milligray imaging maintains geometric and attenuation accuracy with minimal bias; and (3) a large-scale comparison of pediatric brain CT between Siemens Force and NAEOTOM Alpha systems, revealing improved noise and contrast-to-noise performance at reduced dose in photon-counting CT. Together, these results establish a framework for dose-efficient CT protocols across cardiac, renal, and neuro-pediatric imaging.\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EAdvanced Methods for Radiation Dose Reduction in Diagnostic and Interventional Computed Tomography\u003Cbr\u003E\u003Cbr\u003E\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Advanced Methods for Radiation Dose Reduction in Diagnostic and Interventional Computed Tomography"}],"uid":"27707","created_gmt":"2025-11-11 16:50:26","changed_gmt":"2025-11-11 16:51:13","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2025-11-25T15:30:00-05:00","event_time_end":"2025-11-25T17:00:00-05:00","event_time_end_last":"2025-11-25T17:00:00-05:00","gmt_time_start":"2025-11-25 20:30:00","gmt_time_end":"2025-11-25 22:00:00","gmt_time_end_last":"2025-11-25 22:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Teams","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"111531","name":"ms defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
