摘要： By simultaneously administering a chemical using a nuclear species releasing a single photon (a first chemical) and another chemical using a nuclear species releasing a positron to a subject, the cumulative distributions of the respective chemicals are monitored. A plural number of γ-ray detectors, which are circularly located, and a collimator covering some of the γ-ray detectors and rotates along the front face of the γ-ray detectors are provided. Also, an energy discriminating means for discriminating signals having a single photon γ-ray energy (first signals) from signals having annihilation γ-ray energy (second signals) among all of the signals detected by the detectors is provided. Further, the cumulative position of the first chemical is specified based on the signals corresponding to the γ-ray detectors covered with the rotating collimator from the first signals. On the other hand, the cumulative position of the second chemical is specified by determining the signal almost simultaneously observed form the second signals and the positions thereof on the detectors.

摘要： In a particle radiotherapy apparatus which has a passage for allowing movement of a particle beam, this invention provides a particle radiotherapy apparatus with high sensitivity for detection of annihilation radiation pairs even if there is a difference between a point where the particle beam loses energy and a position of a detector ring in a body axis direction of a patient. For the purpose of solving such a problem, the particle radiotherapy apparatus according to this invention includes an elliptic detector ring which is vertically long and is reversibly tiltable. Consequently, annihilation gamma ray pairs are detected with the single elliptic detector ring. Then, annihilation gamma ray pairs occurring inside the elliptic detector ring will be detected. In other words, all annihilation gamma ray pairs will impinge on the single elliptic detector ring at substantially right angles. This inhibits lowering of sensitivity for detection.

摘要： The invention includes disposing guide slit plate mechanisms fixed relative to one another, namely, parallel to and spaced apart from one another by a prescribed distance; fitting metal foils, which serve as X-ray absorbing substance provided between the guide slit plate mechanisms, parallel to primary X-rays; inserting both ends of the metal foils into the guide slit plate mechanisms; inserting, when applying tension evenly, a rod, which is sheathed in an elastic body, into holes formed in the metal foils on the tip sides of the metal foils beyond the inserted portions; and adopting a structure that ensures that the cross sectional shape of the elastic body sheathing the rod has a sufficient wall thickness in a direction in which the elastic body is compressed when tension is generated, and thereby eliminating any difference in the tension even if a spring constant k that is determined during compression is small and the amounts of compression are different.

摘要： Parameters T1, T2, and K required by a scintillator array identification mechanism in a two-stage scintillator γ-ray detector (depth of interaction (DOI)) are accurately and easily determined. The parameters required by the scintillator array identification mechanism are determined with reference to a first signal count ratio, which is obtained by irradiating a γ-ray on each scintillator array with luminescence pulses in an incident depth direction of the γ-ray having different attenuation time during an inspection stage of the γ-ray detector single unit. Furthermore, a second signal count ratio is obtained by irradiating the γ-ray on a front surface of the γ-ray detector single unit, and then a third signal count ratio is obtained by irradiating the γ-ray on the front surface after the γ-ray detector single unit is installed in a PET device.

摘要： In a method of manufacturing a radiation detector according to this invention, a lattice frame 40 is stored in a receptacle 50, and scintillators 1SF and 1SR are also stored therein. The lattice frame 40 and scintillators 1SF and 1SR are once taken out of the receptacle in a state of trial assembly as a two-stage scintillator block in trial assembly 54. The lattice frame 40 and scintillators 1SF and 1SR in trial assembly are stored in the receptacle 50 into which an optical binding material has been poured. This method can reduce trouble occurring in manufacture to realize a radiation detector simply.

摘要： A hollow grid that can be manufactured easily, capable of inhibiting the generation of moire fringes, and absorbing less transmitted X-rays is provided. The hollow grid uses no intermediate material that is capable of transmitting the X-rays. X-ray shielding members are located at intervals of an integral multiple of a pixel pitch of a two-dimensional radiation detector. The X-ray shielding members are held by adhering to the upper and lower wrapping members. Therefore, through a sensitivity correction, the structure, in which the generation of moire fringe is difficult, is provided. Since the hollow grid is assembled by means of an assembling jig, the intervals of the X-ray shielding members can be formed easily with high precision. The quality variation of the completed hollow grids is small, and the product precision is high.

摘要： The rotary cathode X-ray tube equipment of the present invention is constructed so as to permit radiation of X-ray from all directions with respect to the whole circumference of a subject, and is used for x-ray CT. The equipment of the invention is constructed to prevent an X-ray radiation window 40 of a low strength from being influenced by atmospheric deformations of a vacuum vessel 1 or by machining and assembling errors, for example by using a joint portion disposed between the X-ray radiation window and an inner ring and having both a surface perpendicular to a rotational axis of a rotary member and a cylindrical surface parallel to the rotational axis, a face seal formed on the surface of the joint portion perpendicular to the rotational axis, and an axial seal formed on the cylindrical surface of the joint portion parallel to the rotational axis.
