PLEASE USE MATLAB$($OR EXCEL$)$ FOR THE FOLLOWING

Calculate the resolution of a SPECT system for $99mTc$ given the following characteristics. The crystal is $1\mathrm{.}5$

$cm$ thick. The intrinsic resolution of the crystal and electronics is $7mm.$ The collimator is made of lead with

round holes and has the dimensions in which the length of the holes that are between septa is $24mm($i$.$e$.,$ the

thickness of the collimator$),$ the thickness of the walls of each septa is $0\mathrm{.}2mm$ and the distance between

individual septa is $2mm.$ The distance of the radioactive source to the collimator surface is $12cm.$
