What is the term used for tuning an energy window to the spectrum of a given isotope?

The term that describes tuning an energy window to match the spectrum of a specific isotope is referred to as "peaking." In the context of nuclear medicine and imaging, "peaking" involves adjusting the detection system's energy window settings to optimize the sensitivity and specificity for the particular gamma rays emitted by the isotope being used.

This ensures that the system effectively captures the gamma photons within the desired energy range while minimizing the detection of scatter or background noise from other energies. Proper peaking is crucial for maximizing image quality and obtaining accurate quantitative measurements during imaging procedures.

Calibration typically refers to the process of ensuring that the imaging system produces accurate and consistent measurements across a range of conditions, but it does not specifically involve tuning to the isotope's energy spectrum. Detuning would imply adjusting away from the energy of interest, and balancing often relates to the adjustment of various system parameters to achieve optimal performance rather than directly focusing on energy window settings.
