摘要： An energy difference picture processing method comprises the steps of using a semiconductor radiation detector; providing two discriminating levels; dividing X-rays, which have passed through objects, into two kind energy zones; counting X-ray photons to obtain an X-ray picture; assembling, with corresponding coefficients, S(H), S(L), {S(H)}.sup.x and {S(L)}.sup.y, which are exponential functions of the S(H) and S(L), respectively, where S(H) is a logarithmically converted version of a picture of counts in a higher energy band and S(L) is a logarithmically converted version of a picture of counts in a lower energy band; and performing addition, subtraction, multiplication and/or division on these terms to provide a picture in which a particular one of the materials constituting the objects is selectively extracted or removed.

摘要： Transmission images are obtained by radiating X-rays having two different energy levels onto a subject in one direction, and then transformed into logarithmic images, respectively. From these logarithmic images, a contrast ratio due to the two kinds of X-rays having different energies is obtained. From this contrast ratio, the term relating to the thickness of the subject is eliminated, thereby providing information only relating to the quality of the material. By collating the information with the previously measured data of materials, the material of the subject is identified.

摘要： Disclosed are a radiation detector and a method of manufacturing the same. The radiation detector includes a radiation screening member for cutting off radiation incident upon the marginal portions of the radiation incident surface of a semiconductor radiation sensor or a semiconductor radiation sensor array for outputting pulses in correspondence with radiation photons, as well as upon the boundary portions between adjacent sensors. In order to manufacture such a radiation detector, leads are provided by the wire bonding, soldering or bump contacting on the radiation screening member, and at least part of the radiation screening member is then fitted to the semiconductor radiation sensor or the semiconductor radiation sensor array so as to make it electrically connected to the electrodes of the semiconductor radiation sensor or the semiconductor radiation sensor array.

摘要： A radiographic diagnostic apparatus including an X-ray tube for generating X-ray radiation, a line slit for shaping the X-ray radiation into a fan beam, a linear X-ray sensor array for detecting the X-ray radiation, and apparatus for driving the components is provided. The focal spot of the X-ray tube and the line slit are disposed on a straight line that connects between a specified fixed point and the center of the linear sensor array of a line extending therefrom.

摘要： A radiation quantum-counting method and apparatus for producing high resolution radiographic images capable of discriminating soft tissue cancer having a lcm size. The high resolution image is generated by a plurality of radiation sensitive elements, each element including a semiconductor material having a pair of electrodes mounted on opposite faces thereof. Each element is highly sensitive and produces a rapid pulse count since the thickness of the semiconductor material is substantially 0.1-0.5 mm, and the semiconductor material has an effective atomic number greater than 30 and an energy band gap greater than 1.3 eV. As a plurality of radiation quanta emanate from the radiation source, they are received by the plurality of radiation sensitive elements which detect individual radiation quantum and produce a pulse signal for each detected quantum. Coupled to each radiation sensitive element is a pulse amplifier for amplifying the pulse signals. The amplified pulse signals are counted and used to produce radiographic image signals containing details of image gradation. The pulse count may also be stored in a memory and used to provide two-dimensional information when combined with other pulse count data derived when the spatial orientation between the objective body and the radiation source is changed.
