A method to assess image quality for Low-dose PET: analysis of SNR, CNR, bias and image noise.

Initial results with the given data of 16 patients diagnosed as TB demonstrated that 5 × 10(6) counts in the scan could be sufficient to yield good images in terms of SNR, CNR, bias and noise. In the future, more work needs to be done to validate the proposed method with a larger population and lung cancer patient data.
