<p>The present invention relates to a combined collimator for nuclear medicine which is mounted on a detector to guide gamma rays emitted from an isotope element integrated in a specific tissue of a body. A guide path to guide the gamma rays is formed by rotating a partition rotation plate which is composed of multiple pixels at a preset angle. The guide path for the gamma rays is formed by multiple lattice fixing plates which are arranged in parallel with preset intervals, each partition rotation plate which is arranged between the lattice fixing plates in parallel with a preset interval and forms a lattice shape with the lattice fixing plate, each hinge shaft which is fixed to the lattice fixing plate on both ends by passing through the middle part of each partition rotation plate and each lattice fixing plate, each micromotor which is embedded in each hinge shaft, and a control unit which controls the rotation of each partition rotation plate by the hinge shaft by the driving of each micromotor. A collimation effect about a parallel porous type, a diffusion porous type, and a concentration type is integrally obtained with regard to the partition rotation plates by only the software control. Thereby, the physical replacement of different heavy collimators is not required every test.</p> |
