Determination of spatial resolution using TC99M on Spect with distance detector variations
Journal Title: International Journal of Allied Medical Sciences and Clinical Research - Year 2019, Vol 7, Issue 1
Abstract
It is very important to pay attention to the spatial resolution of the SPECT tool regularly every week to ensure the SPECT plane works optimally so that it can produce more accurate image quality. Using the MATLAB program can help to determine the FWHM value and spatial resolution. In the MATLAB program to calculate the value of FWHM using the ESF and PSF methods, the FWHM values obtained the value of spatial resolution. In this research, several detector distances are used to obtain the best spatial resolution values. the spatial resolution obtained is 0.01 lp/mm0.04 lp/mm with different distances. The most optimum value is obtained at a distance of 20cm from the detector with a spatial resolution value of 0.04 lp/mm. Quality Control of spatial resolution of images through FWHM calculations can be calculated using the ESF and PSF methods in the Matlab program
