Claims

[Claims for Utility Model Registration] (1) In an ECT device in which a detector or scintillation camera rotates around a subject by a support arm extending from a stand, a point source that emits parallel and narrow beams of light; , a rotatable first reflector;
A second reflector having a reflective surface parallel to the reflective surface of the first reflector.
An EC characterized by comprising a reflector.
T positioning mechanism. (2) In an ECT device in which a detector or scintillation camera rotates around the subject using a support arm extending from a stand, a light emitting point that generates parallel, narrow beams and is located on the detector rotation axis. source and
A first reflector that is movable back and forth and rotatably disposed on the detector rotation axis, and a second conical reflector that has a reflective surface parallel to the reflective surface of the first reflector on its inner surface. An ECT positioning mechanism characterized in that an annular light beam concentric with a light beam on a detector rotation axis is irradiated with a variable radial distance from the rotation axis. (3) The ECT according to claim 2 of the utility model registration claim, characterized in that the first reflector is a cone having a reflective surface on its outer surface and is displaceable perpendicularly to the detector rotation axis. Positioning mechanism.
