WebJun 15, 2015 · To find the full width half max, it is then probably easiest to look for a point closest to 1- (1-Min [yy])*0.5 in yy. The first thing that came to mind was using Nearest [yy,1- (1-Min [yy])*0.5,1] which indeed returns a value of yy closest to half of the FWHM. But I'm having some trouble finding the actual position of this point in the data. WebFeb 3, 2015 · Methods. Three mathematical methods (direct calculation, global interpolation using gaussian and local interpolation using splines) for calculating FWHM from a line source (planar scintigraphy) were tested and compared. A NEMA Triple Line Source Phantom was used to obtain static images both in air and with different scattering levels.
