The VOIs surface extraction is based on user selectable thresh- old and three-dimensional target flood-fill. Contrast to anatomical vol- ume detection approaches, volumes are determined from functional PET images and the obtained objects are checked against anatomical images. The developed VOI program was evaluated with brain FDOPA-PET studies where the striatum was the object. The results were comparable to entirely manual method and the target extraction time is reduced to about one third of manual method.<\/jats:p>","DOI":"10.3233\/978-1-60750-912-7-339","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T08:47:32Z","timestamp":1740127652000},"source":"Crossref","is-referenced-by-count":0,"title":["Three-dimensional ROIs in Brain PET"],"prefix":"10.3233","author":[{"family":"Mykk&auml;nen Jouni","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Juhola Martti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Ruotsalainen Ulla","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Medical Informatics Europe &amp;apos;99"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T08:56:07Z","timestamp":1740128167000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0926-9630&volume=68&spage=339"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1999]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-60750-912-7-339","relation":{},"ISSN":["0926-9630"],"issn-type":[{"value":"0926-9630","type":"print"}],"subject":[],"published":{"date-parts":[[1999]]}}}
