Thescopeofthebookwaslater- hancedand, inthepresentform, itisacompilationofsomeoftherecentwork usinggeometricpartialdi'erentialequationsandthelevelsetmethodology inmedicalandbiomedicalimageanalysis. Thesynopsisofthebookisasfollows: Inthe'rstchapter, R. Malladi andJ. A. Sethianpointtotheoriginsoftheuseoflevelsetmethodsand geometricPDEsforsegmentation, andpresentfastmethodsforshapes- mentationinbothmedicalandbiomedicalimageapplications. InChapter 2, C. OrtizdeSolorzano, R. Malladi, andS. J. Lockettdescribeabodyof workthatwasdoneoverthepastcoupleofyearsattheLawrenceBerkeley NationalLaboratoryonapplicationsoflevelsetmethodsinthestudyand understandingofconfocalmicroscopeimagery. TheworkinChapter3byA. Sarti, C. Lamberti, andR. Malladiaddressestheproblemofunderstanding di'culttimevaryingechocardiographicimagery.
