Transcranial Doppler ultrasound is widely considered the most convenient system for the detection of microemboli. The most common standard detection is achieved through the Doppler energy signal and depends on an empirically set constant threshold. On the other hand, in the past few years, higher order statistics have been an extensive field of research as they represent descriptive statistics that can be used to detect signal outliers. In this study, we propose new types of microembolic detectors based on the windowed calculation of the third moment skewness and fourth moment kurtosis of the energy signal. During energy embolus-free periods the distribution of the energy is not altered and the skewness and kurtosis signals do not exhibit any peak values. In the presence of emboli, the energy distribution is distorted and the skewness and kurtosis signals exhibit peaks, corresponding to the latter emboli. Applied on real signals, the detection of microemboli through the skewness and kurtosis signals outperformed the detection through standard methods. The sensitivities and specificities reached 78% and 91% and 80% and 90% for the skewness and kurtosis detectors, respectively.<\/jats:p>","DOI":"10.1155\/2016\/3243290","type":"journal-article","created":{"date-parts":[[2016,12,14]],"date-time":"2016-12-14T16:15:31Z","timestamp":1481732131000},"page":"1-8","source":"Crossref","is-referenced-by-count":13,"title":["Detection of Doppler Microembolic Signals Using High Order Statistics"],"prefix":"10.1155","volume":"2016","author":[{"given":"Maroun","family":"Geryes","sequence":"first","affiliation":[{"name":"Universit\u00e9 Fran\u00e7ois Rabelais de Tours, UMR Imagerie et Cerveau Inserm U930, Tours, France"},{"name":"Department of Physics and Electronics, Faculty of Sciences I, Lebanese University, Beirut, Lebanon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7097-7533","authenticated-orcid":true,"given":"Sebastien","family":"M\u00e9nigot","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Fran\u00e7ois Rabelais de Tours, UMR Imagerie et Cerveau Inserm U930, Tours, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Walid","family":"Hassan","sequence":"additional","affiliation":[{"name":"Clarivate Analytics, Dubai, UAE"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Mcheick","sequence":"additional","affiliation":[{"name":"Department of Physics and Electronics, Faculty of Sciences I, Lebanese University, Beirut, Lebanon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0256-905X","authenticated-orcid":true,"given":"Jamal","family":"Charara","sequence":"additional","affiliation":[{"name":"Department of Physics and Electronics, Faculty of Sciences I, Lebanese University, Beirut, Lebanon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2356-885X","authenticated-orcid":true,"given":"Jean-Marc","family":"Girault","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Fran\u00e7ois Rabelais de Tours, UMR Imagerie et Cerveau Inserm U930, Tours, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1007\/s11883-006-0009-9"},{"key":"2","year":"1968"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.30.8.1610"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/s0301-5629(99)00029-0"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.31.6.1335"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/s0301-5629(02)00615-4"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/10.880094"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.ultrasmedbio.2004.03.009"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/s0301-5629(01)00414-8"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/titb.2004.828882"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.patrec.2008.03.015"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1504\/IJBET.2014.059059"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1016\/S0929-8266(00)00104-X"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1161\/01.str.29.3.725"},{"key":"18","first-page":"245","volume-title":"Cerebral microembolism synchronous detection with wavelet packets","year":"2013"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1016\/j.ultrasmedbio.2005.05.001"}],"container-title":["Computational and Mathematical Methods in Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2016\/3243290.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2016\/3243290.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2016\/3243290.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,5,18]],"date-time":"2018-05-18T10:58:01Z","timestamp":1526641081000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/cmmm\/2016\/3243290\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":16,"alternative-id":["3243290","3243290"],"URL":"https:\/\/doi.org\/10.1155\/2016\/3243290","relation":{},"ISSN":["1748-670X","1748-6718"],"issn-type":[{"value":"1748-670X","type":"print"},{"value":"1748-6718","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016]]}}}
