Answer the fоllоwing questiоns аbout how you would design а collimаtor for a standard Anger-type gamma camera, to address the following needs: If you wish to make a collimator more sensitive, what design parameter change(s) would you make? If you wish to make a collimator with better spatial resolution, what design parameter changes would you make? Why can you not simultaneously improve sensitivity and spatial resolution? If you wish to make a collimator work for gamma ray energies above 180 keV, what one design parameter change must be made (relative to a low-energy collimator designed for gamma rays up to 150 keV)?
