Dead time corrections for the 99mTc window measurement of the phantom. Sensitivity (CTc) in kcps/MBq vs. A (MBq) for the second extrinsic phantom measurement, detector 1, 99mTc energy window. Dead time values τTc (i.e., from photopeak windows) from different measurements were used for correction: blue diamonds, uncorrected; red squares, τTc measured in the intrinsic point source measurements (from Table 2); green triangles, τTc from the first extrinsic point sources measurements (Table 4); and cyan circles, τTc from the first scatter phantom measurement (also Table 4)
