  • Publication number: 20250082209
    Abstract: A biological information measurement device includes a pulse acquisition mechanism configured to detect a pulse of a human body, a pulse interval calculation mechanism configured to calculate, based on the pulse, a pulse interval between one beat and a beat immediately before the one beat, and a display mechanism configured to display a level indicator visually indicating at least one of the pulse interval or an amount of change from another pulse interval immediately before the pulse interval. The level indicator indicates, per beat of the pulse detected, the pulse interval or the amount of change.

  • Patent number: 8787647
    Abstract: An image matching device in which, in automatic positioning calculation using an ICP method, a solution is converged to an optimal solution while avoiding reaching a local solution, and a patient positioning device using this matching device. The device includes a CT image data reading unit reading first and second CT image data, a point group data generation unit generating first and second point group data in a three-dimensional space by binarization processing and edge-extraction processing on sliced images of the first and second CT image data, respectively, a point group data resolution conversion unit thinning-out point group data so as to extend a point-group-data array pitch, and an ICP calculation unit obtaining, using an ICP method, a conversion amount for the second point group data so that an error function of the first point group data and the second point group data outputted from the point group data resolution conversion unit is minimized.

  • Publication number: 20100246915
    Abstract: There is provided a patient registration system according to the present invention, including: a CT data capturing device; an X-ray television imaging device; and an image processing device for generating a two-dimensional DRR image based on the captured CT data, and then calculating an amount of displacement between a first diseased site position when the CT data is captured and a second diseased site position when the X-ray television image is captured.

  • Patent number: 5876281
    Abstract: A pulse air jet generator being used for an air shower apparatus. An air flow restricting member, which is so configured as to cross an air flow blown off from an air blowoff nozzle intermittently at part of the rotational locus thereof and to rotate by the air flow, is provided on the air blowoff side of the air blowoff nozzle, and the weight of a rotating portion including the air flow restricting member is unbalanced so that the air flow restricting member is reset to a position corresponding to that of the air blowoff nozzle by the dead weight when the air blowoff is stopped. The air blowoff nozzle is disposed in an annular frame fixed on an air blowoff portion at a position shifted to the outer peripheral side from the center of the annular frame, the rotational center of the air flow restricting member is positioned at the center of the annular frame.
