  • Patent number: 10292669
    Abstract: To improve performance in Photon Counting CT, pixel miniaturization, a reduction in circuit dead time, and dealing with scattered radiation and charge sharing are important. In addition, because the number of circuits increases, a reduction in power consumption of each circuit is important. Under these constraints, circuitry that deals with the scattered radiation is provided. Each pixel includes a circuit that determines whether radiation has been detected by another, adjacent pixel at the same time, and counters that count the radiation are switched on the basis of the result of the determination. On the basis of this result, counts of non-coincident events are primarily used, and coincident counts are used after being corrected, for reconstruction data.

  • Publication number: 20190021685
    Abstract: The present invention is directed to make a photon-counting CT apparatus capable of more accurate data acquisition. Such apparatus is provided with a reference detection unit and a time measuring instrument to measure temporal fluctuations in a rotational direction of an X-ray irradiation unit. The apparatus corrects temporal fluctuations in the rotational direction involved in data measured by the reference detection unit, using time measurement data which is output by the time measuring instrument. Using corrected measurement data measured by the reference detection unit, the apparatus makes corrections of fluctuations pertaining to the X-ray tube of the X-ray irradiation unit and pile-up. Data corrections with high accuracy are thus enabled.

  • 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.

  • 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.
