The width of the measured spectrum for a particular gamma peak directly relates to energy resolution. Energy resolution refers to the ability of a gamma camera to distinguish between gamma rays of different energies. A narrower peak indicates better energy resolution, meaning the system can effectively differentiate between photons of slightly different energies. Conversely, a broader peak means that there is a greater overlap and uncertainty in energy measurement, which can lead to less accurate peak identification.

In the context of gamma cameras, energy resolution is crucial for accurately identifying and quantifying radioisotopes used in nuclear medicine, thus enabling better diagnostic capabilities. By effectively interpreting the width of the gamma peak, practitioners can assess the camera's performance in terms of its ability to resolve energy differences, ensuring optimized imaging and diagnostic outcomes.
