Abstract: A computer-implemented method of analysing nuclear magnetic resonance, NMR, data of a target object is provided. The method comprises receiving NMR data of the target object, and analysing the received NMR data using a model of the diffusive behaviour of 5 particles within the target object. The model includes a time parameter and a space parameter, the time parameter describing temporal characteristics of the diffusive behaviour of particles in the model and the space parameter describing spatial characteristics of the diffusive behaviour of particles in the model. The model is constrained such that the value of the time parameter and the value of the space parameter 10 are related according to a correlation function. An apparatus for analysing nuclear magnetic resonance, NMR, data of a target object is also provided.

Abstract: Disclosed herein is an example method and system for characterizing a biological structure in terms of bio-markers derived from diffusion weighted magnetic resonance imaging (DWI) data of biologic material. A first set of DWI data may be obtained using a fixed diffusion encoding gradient and a plurality of diffusion time resolutions, and a second set of DWI data may be obtained using a fixed diffusion time resolution and a plurality of diffusion encoding gradients. The first and second sets may be analytically fit with a fractional power-law diffusion model parameterized by fractional exponents each uniquely corresponding to one of a plurality of bio-markers of the biologic material. Fractional exponents may be determined from the analytical fitting of the first and second sets of DWI data, and an image of the biologic material may be generated and displayed.

Abstract: The invention disclosed herein provides an example method and system for characterizing a biological structure in terms of bio-markers derived from DWI data. The methodology includes estimating bio-markers in a fixed diffusion time protocol, estimating bio-markers in fixed diffusion encoding gradient strength protocol, calculating parameters of a model, and using the parameters to characterize a biological structure. Using the techniques and methods described herein, the data may be used to identify structural degeneration, structural integrity and response to therapeutics.

Abstract: Blood component processing systems and methods are coupled to a blood component processing device. The systems and methods include a fluid circuit that comprises at least one fluid pressure actuated pump station, at least one fluid flow path communicating with the pump station, and at least one valve in the fluid flow path. A control module is sized and configured to interact with the fluid circuit. The control module includes an actuator to selectively apply fluid pressure to the pump station in concert with operation of the valve to pump fluid through the fluid flow path in response to a control program. A controller coupled to the control module includes the control program and a fluid circuit integrity test function.
