[Video] FLUOSTAR
A realistic replica of an aneurysm that developed in a cerebral blood vessel (internal carotid artery). A three-dimensional geometric shape is reconstructed in actual size from patient CT images, etc., and a model is molded using a thin film of silicone rubber using rapid prototyping technology. A pulsatile functional model with the flexibility of vascular walls in healthy adults. Here, we introduce an example of spatiotemporal measurement of patient-specific blood flow patterns using FLUOSTAR fluorescent particles and 3D stereo PIV technology.
Comparison of Fluostar fluorescent particles (upper row) and non-fluorescent particles (lower row). The images are original and have not undergone any processing to improve image quality. The measurement system used was a standard high-speed camera and a high-speed pulse laser (Nd:YLF, 5mJ/pulse). As you can clearly see from the video, Fluostar fluorescent particles enabled real-time visualization of complex flow behavior near walls for the first time. This shows that wall parameters such as wall shear stress can be accurately quantified. With non-fluorescent particles, the overall flow pattern can be understood from the influence of wall scattering, but it is not possible to get into the important flow near the wall.
Excellent water affinity
Hydrophilic groups are added to the surface of Fluostar particles, which naturally blends with water without forming agglomerations during particle premixing. Enjoy the amazing affinity with water.
