Fig. 3

Relative count difference per VOI between SPECT corrected for dead time using DTCM1 versus DTCM3, in function of the observed wide-spectrum acquisition count rate (phantom, a; patients, b). The dotted line at 158 kcps corresponds to a DTCF equal to 1.1. Tumours are represented by the one tumour per acquisition having the largest difference between DTCM3 versus DTCM1
