  • Patent number: 9554707
    Abstract: Exemplary embodiments are directed to acquiring multiple sets of positron emission tomography (PET) data for different areas of a subject concurrently with acquiring portions of a single magnetic resonance field of view. Positron emission tomography (PET) images and magnetic resonance (MR) images can be acquired using a combined PET-MRI scanner, wherein, for example, a first portion of MR data from a MR field of view can be acquired concurrently with a first acquisition of PET data, a position of the MR field of view can be adjusted in response to a change in a location of a bed in the combined PET-MRI scanner, and a second portion of MR data from the MR field of view can be acquired concurrently with a second acquisition of PET data.

  • Patent number: 9556390
    Abstract: A method includes providing a gasifier with a fuel source comprising a heavy oil, a light oil, and recovered soot. The gasifier may gasify the fuel source to generate a syngas and soot. The method also includes recovering the soot in a first separation unit that may receive a portion of the heavy oil and separate the soot from an extraction oil used to recover the soot. The first separation unit generates soot bottoms that include the portion of the heavy oil and the recovered soot. The method also includes flowing a first separation co-fractionate to a second separation unit. The first separation co-fractionate includes the extraction oil and the light oil. The second separation unit may separate the extraction oil and the light oil, and direct the light oil towards the first separation unit.
