WebStudies have shown that 1% planar non-uniformity can generate as much as ___% non-uniformity in reconstructed images. 20%. T/F You can use a gallon-size bleach bottle for Uniformity testing. True. To test Uniformity using a gallon-size bleach bottle, add _____mCi of 99mTc diluted with water to fill the bottle. WebRegular analyses of uniformity by a computer can facilitate detection of radial deterioration prior to any visible change. Uniformity can be different for different radionuclides and window settings It is thus important to ensure that uniformity is consistent for all radionuclides used on the gamma camera. Further, if non-standard or
