  • Gamma camera, spect device, pet device, and method for generating measured gamma ray images
    Patent number: 9870608
    Abstract: A unit (33) for generating count images for separate energy windows generates main measured count images and auxiliary measured count images on the basis of gamma ray (6) count information measured by a detector head (10). A main measurement window direct ray count rate estimation unit (42) estimates a count rate for direct gamma rays in a main measurement energy window, doing so by subtracting a scattered gamma ray count rate for an auxiliary measurement energy window, which has been estimated from an auxiliary measured count image and detector response data by an auxiliary measurement window scattered ray count rate estimation unit (41), from the main measured count image.

  • INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND INFORMATION PROCESSING PROGRAM
    Publication number: 20170300985
    Abstract: The system controller identifies, for each candidate user, a target item to be sold by a target seller and a comparison item to be sold by another seller than the target seller. The system controller then compares, for each candidate user, transaction terms between the above identified target and comparison items. The system controller changes the transaction terms of the target item so that they become more favorable than or comparable to the transaction terms of the comparison item. The system controller determines, with priority given to candidate users for which a value corresponding to the difference between pre-change transaction terms and post-change transaction terms of the target item is relatively small, a plurality of target users to be notified of the post-change transaction terms.
