High Spatial Resolution Lipid Imaging

Photoplethysmographic imaging of high spatial resolution

We present a new method of formation photoplethysmographic images with high spatial resolution from video recordings of a living body in the reflection geometry. The method (patent pending) is based on lock-in amplification of every pixel of the recorded video frames. A reference function required for synchronous detection of cardiovascular pulse waves is formed from the same frames. The method...

Accelerated High Spatial Resolution Diffusion-Weighted Imaging

Acquisition of a series of anisotropically oversampled acquisitions (so-called anisotropic "snapshots") and reconstruction in the image space has recently been proposed to increase the spatial resolution in diffusion weighted imaging (DWI), providing a theoretical 8x acceleration at equal signal-to-noise ratio (SNR) compared to conventional dense k-space sampling. However, in most works, each D...

Ultra High Spatial Resolution Ion Imaging with a NanoSIMS Ion Microprobe: Applications

Introduction: Ion imaging technique with secondary ion mass spectroscopy (SIMS) is a powerful tool to visualize the distributions of isotopes and/or elements in samples, and is becoming common to variety field of sciences including material science [1], cosmochem-istry [2] and biology [3]. The CAMECA NanoSIMS 50L ion microprobe represents the in-situ microanalysis by SIMS, combining ultra high ...

Photoacoustic lymphatic imaging with high spatial-temporal resolution.

Despite its critical function in coordinating the egress of inflammatory and immune cells out of tissues and maintaining fluid balance, the causative role of lymphatic network dysfunction in pathological settings is still understudied. Engineered-animal models and better noninvasive high spatial-temporal resolution imaging techniques in both preclinical and clinical studies will help to improve...
