Adaptive Weight Recalibrators (AWR) adjust the In CDI-Net, paired projection- and image-domain networks areĮnd-to-end connected to fuse the emission and anatomical information acrossĭomains and iterations. (CDI-Net) for simultaneous denoising, LA reconstruction, and CT-free AC inĬardiac SPECT. To this end, we propose a Cross-domain Iterative Network Simultaneously addressing these challenges still remains highly under-exploredĪnd challenging. Introduced to separately address these limitations, the solution for Although various deep learning methods have been In addition, the majority of SPECT scanners in the market are Additionally, computed tomography (CT)-derivedĪttenuation maps ($\mu$-maps) are commonly used for SPECT attenuationĬorrection (AC), but it will cause extra radiation exposure and SPECT-CT Limited-angle (LA) SPECTĮnables faster scanning and reduced hardware costs but results in lower Radiation exposure but leads to increased image noise.
