Outline of Final Research Achievements |
The purpose of this study was to develop a Hybrid SPECT reconstruction method by a combination of the asymmetric SPECT acquisition, IPDE (Interpolated Projection Data Estimation) method and modified DRAMA (Dynamic RAMLA) reconstruction algorithm. A Hybrid SPECT reconstruction method was evaluated to a two-dimensional Shepp-Logan head numerical phantom with statistical noise and a 3-D brain phantom. Quality of the reconstructed images was evaluated in terms of mean structural similarity (MSSIM) values. The Hybrid SPECT reconstruction method showed faster resolution recovery with lower noise than the asymmetric SPECT acquisition and IPDE method and yielded acceptable images in 2 or 3 iteration. The sensitivity of a gamma camera was also maintained virtually constant during the 3 years.
