  • Patent number: 9921172
    Abstract: A nuclear level sensing gauge for measuring the level of product in a bin utilizes a plurality of scintillators arranged in a serial fashion. A source of nuclear radiation is positioned adjacent the bin, and the scintillators, which may be bundles of one or more scintillating fibers or scintillating crystals, are positioned in a serial fashion adjacent the bin opposite the source of nuclear radiation, such that nuclear radiation passing through the bin impinges upon the bundles. Light guides carry photons emitted by the scintillators—which are indicative of radiation passing through the bin—to a common photomultiplier tube. The tube is connected to electronics which convert counts of photons from the PMT into a measure of the level of radiation-absorbing product in the bin.

  • Patent number: 9069089
    Abstract: Positron emission tomography (PET) systems suitable for use with dirty (positron+prompt gamma) emitters are provided. One or more prompt gamma detectors are added to the PET system, where the prompt gamma detectors are responsive to the prompt gammas provided by the dirty emitter, but are not responsive to 511 keV annihilation photons. The prompt gamma detectors can surround the imaging PET detector array and/or be disposed as end caps relative to a generally cylindrical PET detector array. The prompt gamma detectors need not provide spatial resolution, because coincidence events in the PET detector array are classified as 2-photon or 3-photon events depending on whether or not there is a time-coincident signal from the prompt gamma detectors. One application of this approach is dual isotope PET where distinct tracers labeled with clean and dirty positron emitters are simultaneously imaged.

  • Patent number: 8989845
    Abstract: A CT imaging system (12) generates structural data of a first FOV which is reconstructed by a CT reconstruction processor (52) into a CT image representation. A nuclear imaging system acquires functional data from a second FOV which is smaller than the first FOV. A first PET reconstruction processor (60) reconstructs the functional data into a PET image representation. A fusion processor (64) combines the PET image representation with a map extracted from the CT image representation to generate an extended FOV image representation. A spill-over correction unit (66) and a backscatter correction unit (68) derive spill-over correction data and backscatter correction data from the extended FOV image representation. A reconstruction processor (70) generates a spill-over and backscatter corrected functional image representation based on the spill-over correction data, the backscatter correction data, and the functional data.

  • Publication number: 20150038839
    Abstract: An imaging system includes radiation source (106) that emits radiation that traverses an examination region and a portion of a subject therein and a detector array (114) that detects radiation that traverses the examination region and the portion of the subject therein and generates a signal indicative thereof. A volume scan parameter recommender (120) recommends at least one spectral scan parameter value for a volume scan of the portion of the subject based on a spectral decomposition of first and second 2D projections acquired by the radiation source and detector array. The first and second 2D projections have different spectral characteristics. A console (122) employs the recommended at least one spectral scan parameter value to perform the volume scan of the portion of the subject.

  • Patent number: 8934959
    Abstract: Magnetic resonance (MR) imaging typically has excellent spatial resolution, but relatively poor temporal resolution. In contrast, positron emission tomography (PET) typically has excellent temporal resolution, but poor spatial resolution relative to MR. Resultantly, it is advantageous to use combined PET-MR imaging sequences to create hybrid or enhanced images that reap the benefits of both modalities. A contrast agent (80) that includes both a PET tracer (82) and MR contrast enhancement (86) can be used in such a combined modality setting. The contrast agent (80) also includes a targeting system (84) that allows the contrast agent (80) to pool in a region of interest.

  • Patent number: 8923952
    Abstract: A system and method for performing quantitative lesion analysis in molecular breast imaging (MBI) using the opposing images of a slightly compressed breast that are obtained from the dual-head gamma camera. The method uses the shape of the pixel intensity profiles through each tumor to determine tumor diameter. Also, the method uses a thickness of the compressed breast and the attenuation of gamma rays in soft tissue to determine the depth of the tumor from the collimator face of the detector head. Further still, the method uses the measured tumor diameter and measurements of counts in the tumor and background breast region to determine relative radiotracer uptake or tumor-to-background ratio (T/B ratio).
