摘要： PURPOSE:To easily and rapidly install a neutron reflector by inserting the neutron reflector into the through-space provided in the upper supporting plate of a reactor core and supporting the reflector on the supporting plate in the upper part of the core by freely attachable and detachable supporting means. CONSTITUTION:A supporting fitting 3a is positioned in the central part on one side face of the neutron reflector 36. The supporting fitting 3a of the one neutron reflector 36 is inserted into the notch 3c of the supporting fitting 3b of the neutron reflector 36 adjacent thereto. Leaf springs 4 are respectively provided on the two side faces on both sides of the corer of the neutron reflec tor 36 facing the side face of the beam of the grid of the upper supporting plate 32 of the core. The leaf springs 4 support the neutron reflector 36 in a horizontal direction to restrain the movement thereof. The neutron reflector 36 is pressed to the wall surface of the grid of the upper supporting plate 32 of the core by the spring effect of the leaf springs 4, by which the movement in the horizontal direction is restrained. The easy installation of the neutron reflector to the periphery of the core is possible in this way.

SOLUTION: The radiation imaging apparatus comprises the detector 21 having discrete detection pixels corresponding to pixels and a collimator 30A having a plurality of radiation paths 31. A plurality of detectors 21 face one radiation path 31. A rotational step width is set about a rotational central axis X1 by an angle of θp between the detector 21 at the center of the radiation path 31 and a line connecting adjacent two detectors 21. When a planar projection image with respect to one direction is created, one is obtained by taking projection images with respect to a plurality of predetermined angular positions (the three angular positions, -θp, 0 and +θp) in the circumferential direction about the rotational central axis X1.

摘要： PROBLEM TO BE SOLVED: To reduce the time required for transmission imaging in a nuclear medical diagnostic system and a transmission imaging method for performing transmission imaging using an external radiation source by ensuring a wide field of view using a point radiation source as the external radiation source. SOLUTION: The nuclear medical diagnostic system comprises an imaging apparatus formed with a hole part to which a bed is inserted and an attenuation correction data creation apparatus. The imaging apparatus comprises a plurality of radiation detectors arranged around the hole part and a plurality of gamma-ray generation means arranged in the longitudinal direction of the bed between a radiation detector which is arranged closest to the hole part and the hole part. The plurality of gamma-ray generation means each have a gamma-ray source which is a single-photon emission nuclide and have a structure for emitting gamma rays by either one gamma-ray generation means alternately toward the outside and the hole part. The attenuation correction data creation apparatus creates attenuation correction data on the basis of a detection signal output from the radiation detectors upon the incidence of the gamma rays emitted by the gamma-ray generation means.

摘要： PROBLEM TO BE SOLVED: To provide a medical care system which reduces an exposure dose to a physician in an interview after taking a photograph using a radiopharmaceutical. SOLUTION: The medical care system comprises a medical care server 1 which stores medical care data showing inspection results of imaging using the radioactive medicament and a medical care client 10 which acquires the medical care data from the medical care server 1 to present them. The medical care client 10 has a monitor for indicating the medical care data and a microphone which collects the voice of the physician or a subject. Thereby, the physician can reduce the exposure dose to the physician since it is not necessary to have an interview in the close vicinity to the subject. Also, descriptions of specifying, etc. of an affected part in the interview can be provided more efficiently by displaying a pointer on the monitor. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a circuit simulator capable of accurately analyzing electric characteristics based on the parts arrangement of an electronic/electric equipment and a wiring method among respective parts. SOLUTION: The geometric shape of a part or all of wiring used for a circuit constituting the electric equipment is inputted (21, 22) and an inherent mode related to current distribution in the wiring is calculated based on the shape of the wiring (23). A conductance relation describing the electric characteristics of the wiring part of which geometeric shape is inputted is derived based on the inherent mode calculation (24) and the circuit equation of the whole circuit to be analyzed is derived simultaneously with the conductance relation of another circuit element (25). The circuit equation is numerically solved to calculate the current/voltage characteristics of the circuit to be analyzed (26).
