    Abstract: A method comprising collecting magnetic resonance imaging (MRI) scanner data corresponding to a region of interest, establishing a spectral peak profile associated with at least one metabolite in the region of interest, wherein the spectral peak profile comprises a term in the FID vector signal included in the collected MRI scanner data, selecting at least three counter indices and corresponding points on the spectral peak profile to compute a linear fractional transformation (LFT), computing an N-dimensional vector outlining a spectral circle in a complex plane by applying the LFT to each counter index included in a set of equally-spaced counter indices associated with a three-dimensional spectrum representation of the collected MRI scanner data, shifting the spectral circle to eliminate a baseline offset for a magnitude spectrum associated with the complex plane, rotating the shifted spectral circle to produce a rotated spectral circle.

    Abstract: A declogging assembly (20) is configured for use with a suction conduit (10). The suction conduit has a head (14) at a first end (15) and a vacuum tube connection (16) at a second end (17). The assembly includes a body (30). The body defines a first aperture (32), a second aperture (34), and a third aperture (36). The assembly also includes a plug (40) disposed within the body (30). The plug has a surface (42) configured to contact the head (14) of the suction conduit (10) so as to move the plug from a first position, in which the first aperture (32) is in fluid communication with the second aperture (34), to a second position, in which the first aperture (32) is in fluid communication with the third aperture (36). The assembly (20) also includes a biasing member (50) configured to bias the plug into the first position.
