  • Reverse Data Reconstruction For Optimal Time Sampling Of Counts In Physiological List-Mode Nuclear Imaging

  • US Patent:
    8437836, May 7, 2013
  • Filed:
    May 29, 2009
  • Appl. No.:
    12/995685
  • Inventors:
    Daniel Gagnon - Twinsburg OH,
    Sameer Tipnis - Mayfield Village OH,
    Raymond Muzic - Mentor OH,
  • Assignee:
    Koninklijke Philips Electronics N.V. - Eindhoven
  • International Classification:
    A61B 6/00
  • US Classification:
    600436, 600407, 600410, 382128, 382131, 382132
  • Abstract:
    A diagnostic imaging device includes detector elements () for detecting y-rays indicative of nuclear decay events. Pairs of concurrently detected γ-rays define lines of response (LORs) which are collected, time stamped, and compiled in list-mode. In tissue perfusion studies, it is beneficial to use the data that concurrently maximizes contrast and signal-to-noise ratio in the reconstructed images. Using the list-mode data, events in an adjustable temporal window () are reconstructed and the reconstructed images are analyzed to determine a figure of merit based on contrast and signal-to-noise properties of the image. By iteratively adjusting the temporal window, extending its start point () backwards in time, and repeating the reconstructing, analyzing, and adjusting steps, an image with an optimal figure of merit is obtained.
  • Pixellated Micro-Columnar Film Scintillator

  • US Patent:
    2004004, Mar 4, 2004
  • Filed:
    Aug 27, 2002
  • Appl. No.:
    10/228394
  • Inventors:
    Vivek Nagarkar - Newton MA,
    Sameer Tipnis - Waltham MA,
  • International Classification:
    H05G001/64
  • US Classification:
    378/098800, 250/483100, 250/367000
  • Abstract:
    A method of fabricating an apparatus for an enhanced imaging sensor consisting of pixellated micro columnar scintillation film material for x-ray imaging comprising a scintillation substrate and a micro columnar scintillation film material in contact with the scintillation substrate. The micro columnar scintillation film material is formed from a doped scintillator material. According to the invention, the micro columnar scintillation film material is subdivided into arrays of optically independent pixels having interpixel gaps between the optically independent pixels. These optically independent pixels channel detectable light to a detector element thereby reducing optical crosstalk between the pixels providing for an X-ray converter capable of increasing efficiency without the associated loss of spatial resolution. The interpixel gaps are further filled with a dielectric and or reflective material to substantially reduce optical crosstalk and enhance light collection efficiency.
