A Novel Real-Time Fluorescent Optical Imaging System in Mouse Heart

Cardiovascular images. A novel real-time fluorescent optical imaging system in mouse heart: a powerful tool for studying coronary circulation and cardiac function.

With the advent of tissue regeneration and gene therapy for heart disease, evaluation of coronary circulation and cardiac function in vivo, especially in a disease model, is extremely important. Conventional methods such as microcomputed tomography, high-resolution magnetic resonance angiography, and high-resolution ultrasound have become invaluable tools in cardiovascular research. However, th...

Determination of experimental Tumor Volume of a mouse using optical imaging system in different processing stages

Real-time optical gating for three-dimensional beating heart imaging.

We demonstrate real-time microscope image gating to an arbitrary position in the cycle of the beating heart of a zebrafish embryo. We show how this can be used for high-precision prospective gating of fluorescence image slices of the moving heart. We also present initial results demonstrating the application of this technique to 3-D structural imaging of the beating embryonic heart.

Real-time imaging of tumor progression in a fluorescent orthotopic mouse model of thyroid cancer.

There is a need for a clinically relevant mouse model of thyroid cancer that enables real-time, non-invasive monitoring of tumor growth, progression, and drug response over time. Human thyroid cancer cell lines NPA (papillary) and KAK-1 (anaplastic) were stably transfected to express either red or green fluorescent protein. Cancer cells were injected into the thyroid glands of 8-week-old athymi...

Simulation of a Neutron Detector for Real Time Imaging Applications

Monte Carlo Method is used to simulate a double layer gadolinium-amorphous silicon thermal neutron detector. The detector fabricated in pixel array configuration has various applications including neutron imaging. According to the simulation results, a detector consisting of a gadolinium (Gd) film with thickness of 2-4 ~m, sandwiched properly with two layers of sufficiently thick (-30 ?µm) hydr...
