| Research Abstract |
Three-dimensional (3D) PET with 82Rb yields myocardial image data with much spillover fraction from the blood. To calculate the regional myocardial blood flow (MBF) with 82Rb myocardial 3D PET, we developed a new algorithm to suppress the spillover using a non-uniform least squared fitting with a weighted function using a blood time-activity curve.
