Patent
Tohoku University and Mitaya Manufacturing Co. | Date: 2017-03-08

The present invention provides an evaluation aid which can be used as a phantom (imitation lesion) when a digital X-ray dynamic image thereof is taken and then evaluation is carried out through the digital X-ray dynamic image, and especially an evaluation aid which can be used for evaluating image qualities of a digital X-ray dynamic image for X-ray absorption parts having different X-ray absorption ratios, and an evaluation device provided with such an evaluation aid. The evaluation aid of the present invention is adapted to be used for taking a digital X-ray dynamic image thereof through which evaluation is carried out, and contains a fixed plate (plate-like body) including a plurality of regions having different X-ray absorption ratios; a rotating disk (movable body) having a plurality of wires (wire rods), the rotating disk capable of rotating (moving) with respect to the fixed plate so that the plurality of wires traverse X-ray with which the fixed plate is irradiated; and a driving motor (driving portion) which rotates (moves) the rotating disk with respect to the fixed plate. It is preferred that thicknesses and/or constituent materials of the plurality of regions of the fixed plate are different from each other, so that these regions have the different X-ray absorption ratios.

An object of the present invention is to provide a novel medical application to regenerative medicine that uses pluripotent stem cells (Muse cells). The present invention provides a cell preparation for treating cerebral infarction and sequelae associated therewith that contains SSEA-3-positive pluripotent stem cells isolated from mesenchymal tissue in the body or cultured mesenchymal cells. The cell preparation of the present invention is based on a brain tissue regeneration mechanism by which Muse cells differentiate into nerve cells and the like in damaged brain tissue by administering Muse cells into cerebral parenchyma.

An object of the present invention is to provide a novel medical application to regenerative medicine that uses pluripotent stem cells (Muse cells). The present invention provides a cell preparation for treating chronic kidney disease that contains SSEA-3-positive pluripotent stem cells isolated from mesenchymal tissue in the body or cultured mesenchymal cells. The cell preparation of the present invention is based on a renal tissue regeneration mechanism by which Muse cells are made to selectively accumulate at a site of kidney disease and differentiate into cells that compose the kidney by administering Muse cells intravenously to a subject having the aforementioned disease.

An image display apparatus includes a projection unit configured to project an image and a plurality of concave reflectors in which contact surfaces with optical axes of the concave reflectors with respect to the optical axis of the projection unit are disposed at different angles from one another. A first concave reflector of the plurality of concave reflectors reflects at least a portion of an image projected by the projection unit to form a first image based on the image. A second concave reflector of the plurality of concave reflectors transmits a portion of an image projected by the projection unit and reflects a portion of the image to form a second image based on the image.
