Abstract: A lock device body includes a brake member fastening a rod to lock the rod, a piston that press-opens a pair of pressure-bearing sections of the brake member by using an expansion member to unlock the rod, and an operation element for manually operating the piston, the operation element includes a shaft threaded in a screw hole, a pressure plate formed on one end of the shaft and located in the pressure chamber, and a sealing member disposed on the pressure plate. When the shaft is threaded into a lock release position, an operation end becomes an unextending state while the pressure plate displaces the piston to the lock release position, and, when the shaft is threaded back to a lock position, the operation end extends from the screw hole to the outside while the sealing member seals the screw hole to isolate the screw hole from the pressure chamber.

Abstract: A print control apparatus includes a generating section, a converting section, a calculating section, and a selecting section. The generating section generates intermediate data by analyzing print data, the intermediate data being data in a stage preceding raster data that is a group of pixels. The converting section converts the intermediate data generated by the generating section into the raster data. The calculating section calculates an expected processing time, the expected processing time being an expected time to be spent on converting a predetermined amount of intermediate data generated by the generating section into raster data. The selecting section selects, as a printing speed of a print mechanism unit, any one of plural predetermined speeds by using the expected processing time calculated by the calculating section.

Abstract: An apparatus for multi-energy tissue quantification includes an x-ray imaging system comprises an x-ray source configured to emit a beam of x-rays toward an object to be imaged, a detector configured to receive the x-rays attenuated by the object, and a data acquisition system (DAS) operably coupled to the detector. A computer operably connected to the x-ray source and the DAS is programmed to cause the x-ray source to emit x-rays at each of a first kVp and a second kVp toward the detector, acquire x-ray data from x-rays emitted at the first and second kVp through a region of interest (ROI), and perform a first multi-material decomposition based on the acquired x-ray data. The computer is also programmed to quantify a volume fraction of a first material in the ROI based on the first multi-material decomposition and display the volume fraction of the first material to a user.

Abstract: The present invention is directed to realize an X-ray CT apparatus and a scan control method of performing contrast imaging by a helical shuttle scan with a smaller exposure amount. An X-ray CT apparatus for performing contrast imaging by repeating a reciprocating helical scan on a region in a subject repeats the helical shuttle scan (solid-line arrow) including, in shuttle (broken-line arrow) of a helical shuttle scan using an X-ray of a first X-ray dose, a helical scan using an X-ray of a second X-ray dose higher than the first X-ray dose. The start timing of the helical scan using the X-ray of the second X-ray dose is determined on the basis of a change in the CT number of a region of interest of an image captured by a helical scan using the X-ray of the first X-ray dose.

Abstract: The present invention attempts to reduce an amount of a contrast medium or a patient dose and improve diagnostic efficiency. The conditions for a main scan are designated so that a first scan of scanning a subject with a tube current of a first tube current value fed to an X-ray tube will be performed in order to examine the blood flow in a subject's blood vessel into which a contrast medium is injected. Moreover, the conditions for a main scan are designated so that a second scan of scanning the subject with a tube current of a second tube current value fed to the X-ray tube will be performed in order to image the subject's blood vessel into which the contrast medium is injected. Images of the subject are constructed based on projection data items produced by scanning the subject under the sets of conditions for a main scan.
