    • In one illustrated embodiment two detector arrays are arranged in parallel and only one detector array is impinged upon by the primary radiation beam, the second detector array detecting only the scatter radiation due to the primary beam. Preferably, the second detector array is arranged so as to receive substantially a maximum intensity essentially equal to the scatter radiation impinging on the first detector array. In one example, the output of the second detector array may be simply subtracted from the output of the first detector array so as to obtain an accurate measure of the transmitted primary radiation. In an alternative embodiment, a single detector array is shifted to a second position for detecting only scatter radiation substantially corresponding to the scatter radiation mixed with the transmitted primary radiation.
    • 在一个示出的实施例中,两个检测器阵列平行布置,并且仅一个检测器阵列被主辐射束照射,第二检测器阵列仅检测由于主波束的散射辐射。 优选地,第二检测器阵列被布置成基本上接收基本上等于入射在第一检测器阵列上的散射辐射的最大强度。 在一个示例中,可以简单地从第一检测器阵列的输出中减去第二检测器阵列的输出,以便获得传输的一次辐射的精确测量。 在替代实施例中,单个检测器阵列被移动到第二位置,用于仅检测基本对应于与所传输的一次辐射混合的散射辐射的散射辐射。

    • A computer tomography apparatus has an annular anode which surrounds a detector ring disposed coaxially relative thereto and having a cathode ring also disposed coaxially relative to the anode. The cathode ring has a series of cathodes which are respectively enabled step-by-step to emit electrons onto the anode so as to displace the focus. Each cathode has a deflector unit associated therewith which deflects the focus for that cathode along the circumference of the anode. One or more cathodes with associated deflection units, and an anode section, can be constructed in combination as a module. The number of focus positions is thereby increased, and the time for acquiring a set of image data is significantly reduced.

    • In radiotherapy, for example, a computer-tomogram is to be formed with a conventional relatively low dosage but with sufficient information content to enable the working out of an irradiation plan with a specific selected isodose distribution. Since the normally measured attenuation coefficients are not valid with respect to substantially harder x-radiation or gamma radiation, the present disclosure teaches the introduction of test bodies into the spacial region to be scanned in generating the computer tomograph, such test bodies having the same percentage contents of the same elements as are present in the particular body volume to be examined and having a density which is adapted as far as possible to such body volume, the density however being graduated such that graduated attenuation coefficients are recorded for the test bodies in the resultant computer tomogram. Thus it is possible to find a test body section whose attenuation coefficient is identical with that of the body tissue to be subsequently subjected to radiation therapy. Since this test body section also quantitatively manifests the same elements, the attenuation coefficient of the test body agrees with that of the body tissue to be treated even in the case of radiation energies and types of radiation used in radiotherapy. Thus, by examining the attenuation coefficients of the corresponding section of the test body with the particular type of radiation to be used for radiotherapy, the matrix of attenuation coefficients contained in the computer tomogram may be transcribed into a matrix for the type of radiation to be used for the radiation therapy. This applies not only to x-radiation or gamma radiation, but also any random type of ionizing radiation, such as, for example, electron, proton and neutron radiation. As a further development, two identical test bodies may be arranged on opposite sides of the body during scanning so that the difference between the attenuation coefficients associated with these two test bodies is a measure of the hardening of the x-radiation on passage through the body of the patient. This information enables a refinement in the precision of the remaining attenuation coefficients of the computer tomograph. As a specific example, each test body may contain several hermetically sealed samples of the body substance to be examined, the samples having a known but graduated density.

    • A combination lock wherein the tumblers can be moved to predetermined positions, preparatory to retraction of the locking bolt from extended position, by an electric motor which is controlled by a microprocessor. The microprocessor receives signals from a keyboard or from a disc and can start the motor for the purpose of aligning the normally scrambled tumblers only in response to reception of a predetermined sequence of signals. A manually operated knob can be coupled to a driver for the tumblers in order to change the positions of the tumblers and/or to move the locking bolt between extended and retracted positions independently of the motor. The microprocessor is programmed to start the motor only in response to reception of a predetermined sequence of signals in accordance with a selected combination.

    • A shock wave source has a coil carrier, a planar or concave coil, a membrane consisting of electrically conductive material and a foil consisting of electrically non-conductive material. The membrane is disposed between the coil and the foil so as to be held tightly therebetween but having a perimeter which is capable of substantially unrestrained movement. Upon the application of a high voltage pulse to the coil, the resulting field causes the membrane to be rapidly repelled, however, only the mechanical forces of the membrane act on the foil, with no electromagnetic forces generated by the coil acting on the foil. The resulting pressure pulse is intensified to form a shock wave pulse in a transmission medium adjacent to the foil. The substantially unrestrained perimeter of the membrane disposed between the coil and the foil permits an initial pressure pulse of short duration to be generated, which provides the further advantages of a short approach path, a small focus zone, a high focusing factor, low electrical and thermal stress on the shock wave source and a low acoustic energy output into the body of a patient receiving treatment using the shock wave source.
