Kinetic monitoring of in vivo metabolism of labelled tracers is based on singular value decomposition or Tucker Decomposition of magnetic resonance spectral image data. Data decomposition is used in conjunction with rank reduction to improve signal-to-noise ratio. Rank reduction can be applied in one or more of a spectral, spatial, or temporal dimension. Rank is generally reduced based on a number of expected analytes/metabolites or fit of measured data to a model.

Denoising of dynamic resonance spectroscopic imaging using low rank approximations in the kinetic domain

The System for Continuous Observation of Rodents in Home-cage Environment (SCORHE) was developed to quantify activity levels and behavior patterns for mice housed within a home cage that, optional, may be disposed in a commercial ventilated cage rack. The SCORHE home-cage in-rack design provides daytime and night-time monitoring with the stability and consistency of the home-cage environment. The dual-video camera custom hardware design makes efficient use of space, does not require home-cage modification, and is animal facility user-friendly. In various embodiments, a software application integrates the two video streams to extract several mouse activity measures.

An echo-based single point imaging (ESPI) system () providing high-resolution oxygen images of a sample is disclosed. The ESPI system () employs spin echo detection of the resonance from a spin probe and concurrent Single Point Imaging (SPI) for spatial encoding of the oxygen concentration within the sample. Images are derived by comparing spin echo intensities of two images reconstructed at two time points selected at identical time intervals on either side of a refocusing pulse, eliminating artifacts associated with sample magnetic susceptibility and field inhomogeneity effects.
