HRRT Performance Measurements: Resolution Measurement - NEMA Modified
The spatial resolution (FWHM and FWTM) of the point source response function
in all three directions is determined by forming one-dimensional response functions,
along profiles through the image volume in three orthogonal directions, through the
peak of the distribution. The width of the response functions in the two directions
at right angles to the direction of measurement is approximately two times the FWHM.
Each FWHM (and FWTM) is determined by linear interpolation between adjacent pixels
at half (or one-tenth) the maximum value of the response function. The maximum value
is determined by a parabolic fit using the peak point and its two nearest neighboring
points respectively. Values are converted to distance in millimeters by multiplication
by the pixel size.
