Quality control of Gamma Camera with SPECT System is
highly valuable for assurance performance characteristic. We report the
performance characteristic of gamma camera by intrinsic calibration and
verification measurement. The study has been done using the data from Siemens
Symbia S Series gamma camera by using a point source 99mTc
at the Institute of Nuclear Medicine & Allied Sciences (INMAS), Khulna,
Bangladesh. From intrinsic calibration and verification flood series, the
integral uniformity for the central field of view (CFOV) has been found in
between 4.01% and 2.88% and for the useful field of view (UFOV) has been in
between 4.77% and 4.30%. The differential uniformity for the CFOV has been in
between 1.53% and 2.04% and for the UFOV has been in between 2.32% and 2.77%.
According to Operating Instruction Symbia System S Series manual, uniformity
can compensate for values exceeding 10%, however while integral uniformity
exceed 7%, have to contract Siemens customer service representative. In conclusion, these results show
that the intrinsic uniformity of the gamma camera under this condition is
within an acceptable range; thus the gamma camera working in INMAS is performed
well.
