A prosthesis includes a tubular graft, a prosthetic valve component, an inflow stent, an outflow stent, and a plurality of body stents disposed between the inflow and outflow stents. Each stent is a sinusoidal patterned radially-expandable ring having a first set of crowns and a second set of crowns, with the first set of crowns disposed closer to an inflow end of the tubular graft than the second set of crowns. The prosthesis is configured to be resistant to backfolding and/or buckling during deployment thereof.

A method of extracting particles from a two-dimensional (2D) hologram recorded as part of a digital inline holography system includes reconstructing a three-dimensional (3D) optical field from the recorded 2D hologram. In addition, particles are extracted/segmented from the 3D optical field, wherein segmented particles are identified by particle location in three-dimensional space and a cross-sectional area of the segmented particle. Based on the identified particle location and cross-sectional area, extracted particles are removed from the 2D hologram to generate an updated 2D hologram. These steps are repeated iteratively until a threshold is met.
