    摘要: A thickness-measuring device comprising (i) an X-ray tube unit including an X-ray tube, (ii) an X-ray detector unit including an X-ray detector having a sensor, and (iii) a means for driving the X-ray tube unit and the X-ray detector unit back and forth, in synchronism with each other, widthwise of an object whose thickness is measured and which runs through a pathline between the X-ray tube unit and the X-ray detector unit. A mask is set above the sensor of the X-ray detector to cover it partly; accordingly, the light-receiving area of the light receiver of the X-ray detector is smaller than the whole area of the sensor. Thus, the measuring area per unit time is reduced effectively.

    摘要: A conveyor (12) moves a workpiece (WP) past an x-ray source (14) to detect existence and location of any undesirable material included in the workpiece, such as bones, fat, metal, etc. Thereafter, the conveyor carries the workpiece further, wherein a cutter (22) segments the detected undesirable material from the workpiece into a segmented portion (SP) having a visually recognizable shape, such as square, round, triangular, etc. A worker stationed downstream of the cutter along the conveyor may then easily spot the segmented portion (SP) in a recognizable shape and offload the segmented portion from the conveyor, while leaving the rest of the workpiece (WP) on the conveyor for further processing. Alternatively, a pickup device (24) may be used to automatically offload the segmented portion from the conveyor. A computer (18) keeps track of the locations of the workpiece and the segmented portion at all times.

    摘要: A method and apparatus is disclosed for mapping the relevant material properties of a log, such as knot location and extent. The outer shape of the log under bark is also revealed using this method, and the boundary between the heartwood and sapwood is accurately mapped. The apparatus includes three x-ray sources and arrays of x-ray detectors, for measuring the attenuation of the wood in the log. Deviations in attenuation are related to changes in density, which are indicative of knots and other defects. Accurate estimates of shape, density and knot location render improved sawing decisions at the headrig of a sawmill, which improve the yield of high quality lumber from a given log. The techniques may also be used in a system for sorting logs according to quality.

    摘要: The present invention provides a method and apparatus for non-contacting morphomtry of three-dimensional surface of an object such as a human body in a shorter time period and with higher precision, wherein the present non-contacting morphometry of three-dimensional surface of an object involves a plurality of measuring video heads, Ai, Bi, Ci and Di and a controlling unit for controlling the measuring time of the measuring heads and for processing and storing the obtained data from the measurements. The present method comprises the steps of: placing the object to be measured so that one axis thereof lies along and with an imaginary central axis; placing the object to be measured so that the measuring heads are arranged on each of n (nnull1) planes intersecting the imaginary central axis where the optical axis of each measuring head faces the imaginary central axis and each annular slice of the surface of the object is covered by the sight fields of the m (mnull3) measuring heads; operating simultaneously one group of a plurality of measuring video heads, the sight field of each of which does not substantially overlap with the sight field of the other in the group, and thereafter, operating other group of a plurality of measuring video heads, the sight field of each of which does not substantially overlap with the sight field of the other in the group. The nnullm sets of data thus obtained in the foregoing steps are processed to obtain three-dimensional data.

    摘要: An X-ray computed tomography apparatus monitors the density of a contrast medium injected into a subject with a CT value by a preparation scan so as to adjust the main scan start timing. A guidance output unit outputs guidance to the subject. A control unit compares the CT value of tomographic image data obtained by the preparation scan with the first threshold, supplies guidance data to the guidance output unit to output the guidance to the subject when the CT value has reached the first threshold. The control unit compares the CT value of the tomographic image obtained by the preparation scan with the second threshold different from the first threshold, and starts executing the main scan or preparing the execution of the main scan when the CT value has reached the second threshold.
