Abstract: 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.

Abstract: A wearable Doppler blood flowmeter can be used with an inflatable cuff to measure blood flow, such as for assessing peripheral artery disease (PAD). The present approach can include techniques such as providing or using a wearable acoustic Doppler blood flowmeter, without requiring the intricate manipulation of a handheld Doppler probe. The system can select a pair of acoustic transmitter and acoustic receiver from a set of more than two transducers, including one or more of different locations, orientations, or spacings, such as to vary a targeted region. The RF echo response signal can be translated to an audio response signal. An audio response signal injection circuit can adaptively inject a noise or other enhancement signal, such as to help improve perceptibility of an audible characteristic of pulsatile arterial blood flow. A trained machine learning model can be employed to select or adjust operating settings, to assess diagnostic information, or both.
