Figure 1:
Impact of PMT Gain on Uniformity and Imaging: The figure demonstrates how PMT gain affects uniformity and image quality. Image A shows excellent uniformity with Tc-99m under optimal gain, while Image B highlights hot spot defects with I-131 due to high PMT gain (Image E). After recalibration to normal levels (Image F), uniformity is restored, as shown in Image C. Image D depicts a thyroid scan with defects caused by the non-uniformity in Image B, underscoring the need for proper PMT gain calibration.
