What should be the expected range for Energy Resolution in gamma cameras?

The expected range for Energy Resolution in gamma cameras is ideally between 9% to 14%. This range reflects the ability of the gamma camera to distinguish between different energies of gamma radiation accurately. A lower percentage in energy resolution indicates better performance, meaning the camera can more precisely resolve different energy levels.

Maintaining energy resolution within the 9% to 14% range is critical for obtaining high-quality images and accurate quantitative data in nuclear medicine. If the energy resolution is too wide, it can lead to inaccuracies in determining the energy of the detected photons, thereby affecting the diagnostic information derived from the imaging studies. This range is typically achieved with good quality gamma cameras that have been properly calibrated and maintained according to industry standards.
