This paper presents an overview of this system and the results of its performance tests. For use of the system as a WBC, three high purity germanium (HPGe) detectors installed in a 20-cm-thick iron shielding chamber are linearly arrayed over a subject lying on the bed, whereas two of the three HPGe detectors are placed over the subject\u2019s chest from side to side when using the system as an LC. The new in-vivo system was calibrated using three de-facto phantoms owned by the QST: an adult-male BOttle Manikin ABsorption (BOMAB) phantom, a Lawrence Livermore National Laboratory (LLNL) phantom and a Japan Atomic Energy Research Institute (JAERI) phantom. Monte Carlo simulations were also performed to determine an optimum location for the three detector array in the WBC mode and revealed that the peak efficiency for the BOMAB phantom (662\u00a0keV) was little varied as long as the middle detector was placed above the thorax and abdomen parts of the phantom. The calculated peak efficiencies agreed well with the observed peak efficiencies for photons with energies over 100\u00a0keV. For lung counting, a tentative Minimum Detectable Activity of 241Am was evaluated as 9.5\u00a0Bq for a counting time of 30\u00a0minutes, and a Japanese male subject with an average chest wall thinness (2.27\u00a0cm). The developed system is now ready for use.<\/jats:p>","DOI":"10.1093\/rpd\/ncac226","type":"journal-article","created":{"date-parts":[[2023,10,11]],"date-time":"2023-10-11T22:50:32Z","timestamp":1697064632000},"page":"1848-1852","source":"Crossref","is-referenced-by-count":5,"title":["Development of a new integrated <i>IN-VIVO<\/i> counting system at the QST"],"prefix":"10.1093","volume":"199","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4054-2501","authenticated-orcid":false,"given":"Yuki","family":"Tamakuma","sequence":"first","affiliation":[{"name":"National Institutes for Quantum Science and Technology , 4-9-1 Anagawa, Inage, Chiba 263-8555, Japan"},{"name":"Nagasaki University Center for Radiation Research and Education, , 1-12-4 Sakamoto, Nagasaki 852-8523, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1555-2639","authenticated-orcid":false,"given":"Masayuki","family":"Naito","sequence":"additional","affiliation":[{"name":"National Institutes for Quantum Science and Technology , 4-9-1 Anagawa, Inage, Chiba 263-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6478-249X","authenticated-orcid":false,"given":"Guosheng","family":"Yang","sequence":"additional","affiliation":[{"name":"National Institutes for Quantum Science and Technology , 4-9-1 Anagawa, Inage, Chiba 263-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kotaro","family":"Tani","sequence":"additional","affiliation":[{"name":"National Institutes for Quantum Science and Technology , 4-9-1 Anagawa, Inage, Chiba 263-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2365-749X","authenticated-orcid":false,"given":"Kazuaki","family":"Yajima","sequence":"additional","affiliation":[{"name":"National Institutes for Quantum Science and Technology , 4-9-1 Anagawa, Inage, Chiba 263-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9339-8705","authenticated-orcid":false,"given":"Eunjoo","family":"Kim","sequence":"additional","affiliation":[{"name":"National Institutes for Quantum Science and Technology , 4-9-1 Anagawa, Inage, Chiba 263-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Munehiko","family":"Kowatari","sequence":"additional","affiliation":[{"name":"National Institutes for Quantum Science and Technology , 4-9-1 Anagawa, Inage, Chiba 263-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Osamu","family":"Kurihara","sequence":"additional","affiliation":[{"name":"National Institutes for Quantum Science and Technology , 4-9-1 Anagawa, Inage, Chiba 263-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2023,10,11]]},"reference":[{"key":"2023101113581438400_ref1","doi-asserted-by":"crossref","first-page":"100197","DOI":"10.1016\/j.envadv.2022.100197","article-title":"Reorganization of advanced radiation emergency medicine systems in Japan after the Fukushima nuclear power plant accident","volume":"8","author":"Tatsuzaki","year":"2022","journal-title":"Environ.
