Perineal noise recording as a non-invasive diagnostic method of urinary bladder outlet obstruction: a study in polyvinyl alcohol and silicone model urethrasTim Idzenga
Department of Urology, Sector Furore, Erasmus MC, Rotterdam, The Netherlands
Neurourol Urodyn 24:381-8. 2005..This method induces the risk of urinary tract infection and urethral trauma. We studied perineal noise recording as an alternative, non-invasive diagnostic method in three flexible/extensible model urethras and two silicone tubes...- Finite element modeling and intravascular ultrasound elastography of vulnerable plaques: parameter variationRadj A Baldewsing
Biomedical Engineering, room Ee 23 02, Thoraxcenter, Erasmus Medical Center Rotterdam, P O Box 1738, Rotterdam 3000 DR, The Netherlands
Ultrasonics 42:723-9. 2004..To understand and quantify the influence of these parameters upon measured IVUS elastograms, they were varied in a finite element model (FEM) that simulates IVUS elastograms of vulnerable plaques... - A finite element model for performing intravascular ultrasound elastography of human atherosclerotic coronary arteriesRadj A Baldewsing
Biomedical Engineering, Thoraxcenter, Erasmus Medical Center Rotterdam, Rotterdam, The Netherlands
Ultrasound Med Biol 30:803-13. 2004..As such, the FEM may help in quantifying strain-dependencies and assist in tissue characterization by reconstructing a Young's modulus image from a measured elastogram... - Assessment of vulnerable plaque composition by matching the deformation of a parametric plaque model to measured plaque deformationRadj A Baldewsing
Biomedical Engineering, room Ee 23 02, Thoraxcenter, Erasmus Medical Center Rotterdam, PO Box 1738, 3000 DR Rotterdam, The Netherlands
IEEE Trans Med Imaging 24:514-28. 2005..2/4 kPa, EM = 16.8/16, for the in vitro plaque EL = n.a./29, EM = n.a./647, EC = n.a./1784 kPa and for the in vivo plaque EL = n.a./2, EM = n.a./188, Ec = n.a./188 kPa... - Robustness of reconstructing the Young's modulus distribution of vulnerable atherosclerotic plaques using a parametric plaque modelRadj A Baldewsing
Biomedical Engineering, Thorax Centre, Erasmus Medical Centre Rotterdam, Rotterdam, The Netherlands
Ultrasound Med Biol 31:1631-45. 2005..Furthermore, reconstructions were 1. independent of catheter position and 2. independent of strain noise. As such, this method has potential to monitor robustly and quantitatively atherosclerosis in vivo... - Local elasticity imaging of vulnerable atherosclerotic coronary plaquesRadj A Baldewsing
Biomedical Engineering, Thorax Center, Erasmus Medical Center, Rotterdam, The Netherlands
Adv Cardiol 44:35-61. 2007..This chapter describes the terminology and pathophysiology of vulnerable plaques and discusses the techniques behind, the methods for and the validations of the elasticity imaging techniques... - Young's modulus reconstruction of vulnerable atherosclerotic plaque components using deformable curvesRadj A Baldewsing
Biomedical Engineering, Thorax Centre, Erasmus Medical Centre Rotterdam, Rotterdam, The Netherlands
Ultrasound Med Biol 32:201-10. 2006..Consequently, this method may become a valuable tool for the quantification of both the morphology and stiffness of vulnerable atherosclerotic plaque components... - Intravascular palpography for vulnerable plaque assessmentJohannes A Schaar
Thoraxcenter, Erasmus Medical Center, Rotterdam, The Netherlands
J Am Coll Cardiol 47:C86-91. 2006..The clinical utility of this technique is yet to be determined, and more investigation is needed...
