Department of Radiology, Stanford University Medical Center, 300 Pasteur Drive, Room S 072, Stanford, CA 94305 5105, USA
Acad Radiol 16:646-53. 2009..We aimed to quantitatively and qualitatively assess the precision of a knowledge-based centerline-extraction algorithm in patients with occluded femoro-popliteal artery (FPA)...
- Femoropopliteal artery centerline interpolation using contralateral shapeDavid N Tran
School of Medicine, Stanford University, Stanford, California 94305 5105, USA
Med Phys 34:3428-35. 2007..13, which were almost always more accurate than the PCA algorithm. We conclude that the use of contralateral shape information, when available, is a promising method for the interpolation of centerlines through arterial occlusions...
- Knowledge-based interpolation of curves: application to femoropopliteal arterial centerline restorationTejas Rakshe
Department of Electrical Engineering, 318 Campus Drive, James H Clark Center, MC 5450, S 355, Stanford University, Stanford, CA 94305, USA
Med Image Anal 11:157-68. 2007..The results were consistently better than those using the MMSE method. Multivariate regression analysis found that OL and the root-mean-square error in the 2 cm proximal and distal to the occlusion accounted for most of the error...
