Determination of Gamma Camera's Calibration Factors for Quantitation of Diagnostic Radionuclides in Simultaneous Scattering and Attenuation Correction.
Asgari A, Ashoor M, Sarkhosh L, Khorshidi A, Shokrani P. Asgari A, et al. Curr Radiopharm. 2019;12(1):29-39. doi: 10.2174/1874471011666180914095222. Curr Radiopharm. 2019. PMID: 30215339
The equations for bone phantom were RTc = -30d + 300 and RSm = - 10d + 100, and the relative errors were 5.4% and 5.6%. The R and d are in terms of cpm/mCi and cm. Besides, the collimators' impact was evaluated on the camera response, and the relevant equations were obtain …
