An evaluation of automated measurement of slice sensitivity profile of computed tomography image: field of view variations

This study aims to evaluate the automated measurement of slice sensitivity profile (SSP) on American Association Physicists in Medicine (AAPM) computed tomography (CT) performance phantom for variations thickness and field view (FOV). The AAPM CT was scanned using a Philips MRC 880 Scanner FOV. values were 1, 3, 5 mm. FOV 240, 300, 340, 400, 440 SSPs their fullwidth at half maximums (FWHMs) automatically measured from middle stair object phantom. To validate results, FWHM obtained compared those manual measurements. differences between FWHMs measurements set thicknesses are less than 0.3 mm, while 0.2 results closer SSP provides high accuracy precision both variations.
