In this paper, we present image-based algorithms for computing the deformations of a volumetric image during a needle insertion in real-time. The algorithms are based on diffusive and linear elastic finite difference methods as utilized in image registration. For an evaluation, the methods are compared to a finite element simulation of the pre-puncture phase of a needle insertion. Furthermore, the methods are improved and tested; contrary to our assumption, an improved diffusion based approach outperforms a linear elastic approach. The algorithms are used to perform a VR simulation of a needle insertion with visuo-haptic feedback.<\/jats:p>","DOI":"10.3233\/978-1-61499-209-7-136","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T15:26:30Z","timestamp":1740151590000},"source":"Crossref","is-referenced-by-count":1,"title":["Optimized Image-Based Soft Tissue Deformation Algorithms for Visualization of Haptic Needle Insertion"],"prefix":"10.3233","author":[{"family":"Fortmeier Dirk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Mastmeyer Andre","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Handels Heinz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Medicine Meets Virtual Reality 20"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T15:37:59Z","timestamp":1740152279000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0926-9630&volume=184&spage=136"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-209-7-136","relation":{},"ISSN":["0926-9630"],"issn-type":[{"value":"0926-9630","type":"print"}],"subject":[],"published":{"date-parts":[[2013]]}}}
