Abstract: Provided are a permanent-magnet motor rotor, a permanent-magnet motor and a method for processing a permanent-magnet motor rotor, relating to the field of motor technology. The permanent-magnet motor rotor includes a rotatable shaft, a silicon steel sheet member and a plurality of magnetic tiles. The silicon steel sheet member is sleeved on the rotatable shaft. The plurality of magnetic tiles are secured around the silicon steel sheet member at intervals. Two circumferential ends of each of the plurality of magnetic tiles are inclined with respect to the axis of the each of the plurality of magnetic tiles and inclined in directions opposite to each other to form two beveled surfaces. Beveled surfaces, facing to each other, of two adjacent ones of the plurality of magnetic tiles are disposed in parallel.

Abstract: The present invention provides a detector and an emission tomography device including the detector. The detector comprises: a scintillation crystal array comprising a plurality of scintillation crystals; and a photo sensor array, coupled to an end surface of the scintillation crystal array and comprising multiple photo sensors. At least one of the multiple photo sensors is coupled to a plurality of the scintillation crystals respectively. Surfaces of the plurality of the scintillation crystals not coupled to the photo sensor array are each provided with a light-reflecting layer, and a light-transmitting window is disposed in the light-reflecting layer on a surface among the surfaces adjacent to a scintillation crystal coupled to an adjacent photo sensor. The detector has DOI decoding capability. No mutual interference occurs during DOI decoding, and decoding is more accurate.
