  • Patent number: 11033246
    Abstract: A radiographic imaging apparatus for capturing a radiographic image by emitting radiation onto an object to be imaged comprises: a storage device for storing therein imaging conditions for a radiographic image; a control device for controlling several sections in the radiographic imaging apparatus to perform preparation for the image capture based on the imaging conditions loaded from the storage device; and an input device for accepting an input by an operator, wherein the input device is configured to accept an input of a result of a decision by the operator as to whether or not to modify the imaging conditions loaded from the storage device, and the control device controls several sections in the radiographic imaging apparatus to start the preparation for the image capture before the input device accepts the input of the result of the decision.

  • Publication number: 20190130598
    Abstract: A CT apparatus comprises: a gantry; a table on which a subject to be examined is laid; a sensor section for acquiring distance data for determining a distance between a body part to be imaged of the subject and the sensor section; a height-data generating section for generating height data containing data of a height of the body part to be imaged of the subject based on the distance data; and a detecting section for detecting said body part to be imaged based on the height data, wherein the sensor section has a field-of-view region RV representing a region in which it is possible to acquire the distance data, and the field-of-view region RV is defined so that a portion of the table on a side of the gantry falls within the field-of-view region RV and a portion of the table on a side opposite to the side of the gantry falls outside the field-of-view region RV.

  • Publication number: 20060104422
    Abstract: An object of the present invention is to concurrently perform the horizontal movements of a cradle and a table in a desirable manner and to desirably prevent interference of the table with a gantry. A microprocessor controls and interlocks a horizontal cradle movement mechanism and a horizontal table movement mechanism. The microprocessor concurrently performs the horizontal movements of the cradle and table. If an operator tries to vary a table height or a tilt angle, the microprocessor performs arithmetic operations to check if the table will interfere with the gantry at a current scan-time position, at which the table should be located during scanning, in the varied state. If the interference is predicted, the table is pulled out of the bore of the gantry until it reaches a position at which the table will not interfere with the gantry.

  • Patent number: 4128378
    Abstract: Equipment for producing a high voltage rectifying unit wherein there is a resin ingredient tank and a curing agent tank for storing separately the resin ingredient and the curing agent, a closed mixer for mixing the resin ingredient and the curing agent, a vacuum chamber for injecting a mixed thermo-setting resin composition into the high voltage rectifying unit, a chamber for defoaming the injected resin composition, a furnace for curing the injected resin composition by heating, and a carrier apparatus covered to isolate the external atmosphere which may carry the resin composition-injected high voltage rectifying unit from the defoaming chamber to the curing furnace, whereby the procedures from vacuum injection to curing can be carried out continuously and automatically.
