AB  - This paper proposes a new sequential weighted least squares (SWLS) method for 
      positron emission tomography (PET) reconstruction. The SWLS algorithm is 
      noniterative and can be considered as equivalent to the penalized WLS (PWLS) 
      method under certain initial conditions. However, a full implementation of SWLS 
      is computationally intensive. To overcome this problem, we propose a simplified 
      SWLS as a reasonable alternative to the SWLS. The performance of this SWLS method 
      is evaluated in experiments using both simulated and clinical data. The results 
      show that the method can be advantageously compared with the original SWLS both 
      in computation time and reconstruction quality.
