A multi-hole nuclear medicine system collimator, low-energy is a device used in diagnostic nuclear medicine imaging to filter gamma rays emitted from radiopharmaceuticals in the body. It is made of lead or lead-equivalent material with numerous small holes arranged to match the detector crystal, allowing only gamma rays traveling straight on to reach the scintillator for image formation.
This category of device is typically supplied as a detachable component for nuclear medicine gamma cameras and is regulated based on its role in imaging performance and safety. It is not a standalone diagnostic tool but functions as an essential accessory that must be compatible with specific detector heads, and its design ensures proper alignment and safe handling during use and maintenance.
