  • Patent number: 10531846
    Abstract: The present technology describes various embodiments of positron emission tomography (PET) systems for use with mammography machines and associated devices and methods. In several embodiments, a PET system includes a tissue platform and one or more PET detection panels removably coupled to the mammography machine. The panels are configured to generally surround the tissue platform and obtain an approximately 360 degree data sample of tissue. The system can further include an output device configured to output the data sample for image reconstruction. In some embodiments, the system is configured to provide high resolution images, quantitative image accuracy, dynamic imaging, and/or biopsy guidance.
    Type: Grant

  • Patent number: 6771802
    Abstract: An imaging probe system includes a portable imaging gamma ray probe and a computer, and is used to locate and examine the distribution of radiation concentrated in animal tissue. The imaging probe system can operate in an imaging mode, a non-imaging mode (simple counting mode), or both simultaneously. The imaging probe system may include smart algorithms that analyze subdivisions of the images and indicate to the user via an audio indicator, a visual indicator, or both, the presence of one or more high-density concentrations of radiation within the image. The determination of such concentrations is governed either spatial resolution requirements of the subdivided image, or based on statistical variations of the cumulative number of particles detected. The imaging probe can also display the count of the detected radioactivity.
