摘要:
One dimensional X-ray image sensor (3) is comprised of a plurality of unit detecting devices (3u) aligned in a row and a filter (4) which covers a portion thereof and is made of a material having an X-ray absorption coefficient equal to or nearly equal to that of a target material (7,8) to be inspected. Also, an X-ray inspection apparatus including the one dimensional X-ray image sensor is disclosed. It includes further a data processor (28) for correcting measured values using data measured in regard to the filter.
摘要:
A three-dimensional picture image pickup apparatus picks up a plurality of two-dimensional picture images of the objective (1) naturally from different directions sequentially at a predetermined time interval regardless of a depth of the objective or the light source etc. The picture images are reproduced sequentially at the predetermined time interval by a picture image reproducing device (41) and deflected into a plurality of directions by a picture image deflection device (42) to display a three-dimensional picture images.
摘要:
Radiation transmission intensity information obtained from a radiation source (41) of two different energy levels or energy bands is used to perform an energy subtraction calculation and to quantify the constituent substances of the object (45) being analyzed in a single operation using a single subtraction calculation equation. When three substances (11-13;21-23;31-33) are overlapping in the direction of radiation transmission, using the transmission intensity information from a radiation source with only two energy levels, the effect of one substance is eliminated while identifying and quantifying the other two by applying an energy subtraction calculation process. Based on the calculated result for the area containing the first and second substances, the density of the third substance can be obtained.
摘要:
Disclosed are a radiation detector and a method of manufacturing the same. The radiation detector includes a radiation screening member (4) for cutting off radiation (1) incident upon the marginal portions of the radiation incident surface of a semi-conductor radiation sensor or a semiconductor radiation sensor array (2) for outputting pulses in correspondence with radiation phontons, as well as upon the boundary portions between adjacent sensors (7a). In order to manufacture such a radiation detector, leads (3a) are provided by the wire bonding, soldering or bump contacting on the radiation screening member, and at least part of the radiation screening member (4) is then fitted to the semiconductor radiation sensor or the semiconductor radiation sensor array (2) so as to make it electrically connected to the electrodes (3) of the semiconductor radiation sensor or the semiconductor radiation sensor array (2).
摘要:
In the energy separated quantum-counting radiography of the present invention, the radiation rays having penetrated through an object body are detected as pulses and the pulses are counted for each radiation ray energy group, namely, each pulse wave height group at a time, thereby to obtain speedily a high resolutive radiation image with regard to various materials of the object body.
