In this scenario, being able to treat bone oncology patients by means of minimally invasive techniques can be crucial to avoid surgery-related risks and decrease hospitalization times. The use of microwave ablation (MWA) is gaining broad clinical acceptance to treat bone tumors. It is worth investigating temperature variations in bone tissue undergoing MWA because the clinical outcomes can be inferred from this parameter. Several feasibility studies have been performed, but an experimental analysis of the temperature trends reached into the bone during the MWA has not yet been assessed. In this work, a multi-point temperature study along the bone structure during such treatment is presented. The study has been carried out on ex vivo bovine femur and tibia, subjected to MWA. An overall of 40 measurement points covering a large sensing area was obtained for each configuration. Temperature monitoring was performed by using 40 fiber Bragg grating (FBGs) sensors (four arrays each housing 10 FBGs), inserted into the bones at specific distances to the microwave antenna. As result, the ability of this experimental multi-point monitoring approach in tracking temperature variations within bone tissue during MWA treatments was shown. This study lays the foundations for the design of a novel approach to study the effects of MWA on bone tumors. As consequence, the MWA treatment settings could be optimized in order to maximize the treatment effects of such a promising clinical application, but also customized for the specific tumor and patient.<\/jats:p>","DOI":"10.3390\/s20113200","type":"journal-article","created":{"date-parts":[[2020,6,5]],"date-time":"2020-06-05T03:32:21Z","timestamp":1591327941000},"page":"3200","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Multipoint Temperature Monitoring of Microwave Thermal Ablation in Bones through Fiber Bragg Grating Sensor Arrays"],"prefix":"10.3390","volume":"20","author":[{"given":"Elena","family":"De Vita","sequence":"first","affiliation":[{"name":"Department of Engineering, University of Naples \u201cParthenope\u201d, Centro Direzionale Isola C4, 80143 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4849-6212","authenticated-orcid":false,"given":"Martina","family":"Zaltieri","sequence":"additional","affiliation":[{"name":"Department of Engineering, Universit\u00e0 Campus Bio-Medico di Roma, Via Alvaro del Portillo, 00128 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesca","family":"De Tommasi","sequence":"additional","affiliation":[{"name":"Department of Engineering, Universit\u00e0 Campus Bio-Medico di Roma, Via Alvaro del Portillo, 00128 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3090-5623","authenticated-orcid":false,"given":"Carlo","family":"Massaroni","sequence":"additional","affiliation":[{"name":"Department of Engineering, Universit\u00e0 Campus Bio-Medico di Roma, Via Alvaro del Portillo, 00128 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eliodoro","family":"Faiella","sequence":"additional","affiliation":[{"name":"School of Medicine, Universit\u00e0 Campus Bio-Medico di Roma, Via Alvaro del Portillo, 00128 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9227-5535","authenticated-orcid":false,"given":"Bruno Beomonte","family":"Zobel","sequence":"additional","affiliation":[{"name":"School of Medicine, Universit\u00e0 Campus Bio-Medico di Roma, Via Alvaro del Portillo, 00128 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3540-7316","authenticated-orcid":false,"given":"Agostino","family":"Iadicicco","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Naples \u201cParthenope\u201d, Centro Direzionale Isola C4, 80143 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9696-1265","authenticated-orcid":false,"given":"Emiliano","family":"Schena","sequence":"additional","affiliation":[{"name":"Department of Engineering, Universit\u00e0 Campus Bio-Medico di Roma, Via Alvaro del Portillo, 00128 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rosario Francesco","family":"Grasso","sequence":"additional","affiliation":[{"name":"School of Medicine, Universit\u00e0 Campus Bio-Medico di Roma, Via Alvaro del Portillo, 00128 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2987-9122","authenticated-orcid":false,"given":"Stefania","family":"Campopiano","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Naples \u201cParthenope\u201d, Centro Direzionale Isola C4, 80143 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"390","DOI":"10.1038\/35077256","article-title":"Cancer epidemiology in the last century and the next decade","volume":"411","author":"Peto","year":"2001","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"351","DOI":"10.1148\/radiol.10081634","article-title":"Principles of and Advances in Percutaneous Ablation","volume":"258","author":"Ahmed","year":"2011","journal-title":"Radiology"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"323","DOI":"10.2214\/ajr.174.2.1740323","article-title":"Thermal Ablation Therapy for Focal Malignancy","volume":"174","author":"Goldberg","year":"2000","journal-title":"Am.
