Characterization for high dynamic range imaging [PDF]

, 2008
In this paper we present a new practical camera characterization technique to improve color accuracy in high dynamic range (HDR) imaging. Camera characterization refers to the process of mapping device-dependent signals, such as digital camera RAW images,

Computed Tomography‐ and Photoacoustic Imaging‐Active Bioresorbable Electrospun Bismuth Nanoparticle‐Infused Small‐Diameter Vascular Grafts

Advanced Healthcare Materials, EarlyView.
A polymeric graft loaded with radiopaque bismuth nanoparticles is expected to undergo gradual polymer resorption and nanoparticle release. This design enables noninvasive, multimodal monitoring of device integrity, patency, and degradation using computed tomography alongside ultrasound and photoacoustic imaging over 12 weeks.

Self‐Assembling Copolymers Encapsulating Single Endothelial Cells Induce Endogenous ECM Deposition and Vascular Regeneration

Advanced Materials, EarlyView.
This study presents the first demonstration of stable sub‐50‐micron single‐cell GPM vesicles fabricated through the intrinsic self‐assembly of an amphiphilic copolymer. Hierarchical assembly of cell containing GPM vesicles into microspheres enable tunable, sustained cell delivery with immune protection.
