A Nuclear Medicine (N-M) imaging system gantry comprising:

• at least one stationary stator;
• at least one rotor rotatably mounted on said stator and including at least one detection unit having at least one Multi-Pixel Photon Counter (MPC);
• and
• at least one rotor driving assembly comprising:
• at least one motor;
• and
• a flat driving belt mounted on a peripheral flat surface of said rotor and driven by said motor;
• wherein said rotor driving assembly comprises at least one driving belt tensioning system;
• and
• wherein said N-M imaging system comprises at least one controller in communication with at least said rotor driving assembly and a level of friction between said belt and said peripheral flat surface is controlled by said controller.
