Background Previously, we proposed interpolated averaged CT (IACT) for improved attenuation correction (AC) in thoracic PET/CT. This study aims to evaluate its feasibility and effectiveness on cardiac PET/CT. Methods We simulated 18F-FDG distribution using the XCAT phantom with normal and abnormal cardiac uptake. Average activity and attenuation maps represented static PET and respiration average...
Previously we proposed interpolated averaged CT (IACT) as a low dose alternate of cine average CT (CACT) for improved PET/CT attenuation correction (AC) in oncology and cardiology applications. This study aims to evaluate the effectiveness of both average CT protocols in myocardial perfusion SPECT/CT. We simulated a patient injected with Tc-99m-sestamibi using the digital 4D Extended Cardiac Torso...
Previously we demonstrated the effectiveness of the interpolated average CT (IACT) for attenuation correction (AC) in PET in simulations and clinical patients. This study aims to evaluate the performance of IACT for thoracic lesions with different sizes, uptake ratios and locations. The XCAT phantom was used to simulate noisy 18F-FDG distribution based on the clinical count level with respiratory...
