Fig. 2From: Feasibility of positron range correction in 82-Rubidium cardiac PET/CTAxial view of the NEMA NU-4 phantom for the uniform, cold and rod region, shown for 40 iterations with no PRC, TD 2 and TDSV 41. All images are shown with the same intensity window. PRC = positron range correction; TD = tissue-dependent; TDSV = tissue-dependent spatially variantBack to article page
