The objective of this study was to the created surface of quantitative uptake value with radioactive tracer PET/CT in normal Thai brain. The surface was generated from the matrix of quantitative uptake value by MATLAB software. Data of PET/CT image was modified to High dynamic range imaging file format by MRI convert and merge together with ana75-2.mat, in this step surfacedata.mat was obtained. The surface data was taken to create a surface of quantitative uptake value to observing the distribution of radiopharmaceuticals in the region of interest.
